I think the M8 will be the last of the air cooled built in mass. The pan American revolution engine will likely start crossing platforms. The sportster died in Europe due to their emissions. Great place for the revolution to debut
I just finished all upgrades to my 14 SGS 103 to 110. It’s done! All air cooled with love jugs. Runs just as I hoped it would. I pull a trailer and wanted low end power. It pulls like a train😊. Anyhow, if I were in market, I would prefer a total water cooled scooter like the challenger. I hope H-D will offer a full dressed challenger… challenger. I would seriously consider it. Hell, I would buy a challenger if it had lower fairings with speakers along with the tour pack.
Great video, I had just learned about the twin cooling. Wonder why it has not crept down into all the touring models? They really did a good job hiding the coolers. If I were looking at a Street or Road glide special I would consider. But its a big $$ jump up from the base model.
It doesn’t work, my 2014 cooling system failed twice and most people I know with this same setup have had water pump failures, right up to present day. It’s a similar situation to hydraulic clutches, Harley just can’t get them to work. They finally gave up on the hydraulic clutches and should give up on the liquid cooling.
A couple of years ago we were on a 2 week crosscountry trip. One RG, my Ultra Ltd and a 2014 CVO Ltd twin cooled. All three bikes had Trask turbos installed. All of us were pulling 300 lb camper trailers. The second day in on a Sunday, the CVO water pump failed. We were an hour or so to a dealer so we headed there, keeping an eye on temps but of course they were closed. We were sitting in the parking lot trying to decide what to do when a bike pulled in and asked if we were ok. Told him our situation and he said "just ride it, wont be a problem". We were a little skeptical until he told us he was the head mechanic at another HD shop. We didnt have much choice so we carried on, again watching out for temps and knocking. Following day we tried to find new water pump but they were out of stock because a lot of people were having failures. Long story short, we continued our 2 week trip and put about 5000 miles on the CVO without the water pump working with no issues at all. Got home and replaced the old pump with the new upgraded pump. Bike is still running like a champ.
Bought a 2014 Ultra Limited brand new. 40,000+ miles on it now, no coolant or water pump problems so far. Traded in a Gold Wing for it. I do have to admit, the Gold Wing was almost as reliable as the Harley. But not quite.
I own a 15 CVO RG Ultra that is twin cooled. I live in western Arizona where Temps can be very extreme. I love the liquid cooling simply because of being in situations (city traffic and lights) when my cooling fans engage and I know my motor is in need cooling and traffic doesn't permit it. Its a nice advantage and I'm at 75,000 miles and I've never had an issue with the cooling system 👍👍👍
2014 Ultra Limited - H2O Pump went out @ 30k (P1019). Was 100+ miles away, called mech said it was fine to ride home, just keep it under 3k RPM's. $500 later = fixed ($300 upgraded part / $200 labor). There was a recall for later Rushmore models and if you find that your H2O pump fails (and it will) do not replace it with OEM, get the upgraded 2017/2018 part. As to selling these twin cooled bikes to the "look at me ppl", have owned & ridden many HD air/oil-cooled bikes over the years & at my age now can afford + appreciate my rolling couch - I still ride in the rain / heat / etc... but now do it in style and comfort!
I live in Perth West Australia 🇦🇺 and rode my 03 fatboy on 42 degree Celsius for 600km no power loss and no issue of what so ever, no need for extra headaches of radiator, thermostat,water pump, coolant and extra $$$ in maintenance Ride safe everyone
Yep. Rode north from Blue Mountains for 2000km middle of summer on my stock Sporty. No issues. I have nothing against water cooling. But everything I own is air cooled. Even my car, which my brother drove from Sydney to Perth and back in 45°C days through summer.
I had a 2007 Street Glide with the 96 twin cam and then purchased the 2015 Ultra Limited 103 twin cooled and now have a 2021 Ultra Limited 114 twin cooled. To be honest with you I didn't give much thought about it. I didn't feel that much difference between all three of my bikes. I just installed the Harley Davidson cool fan a couple of weeks ago will see if it helps with heat. Thank you for sharing the video.
When my 15 Limited water pump failed at 8k I still road it in the heat for almost a month before I brought it in for the new #p/n pump and so far so good currently at 40k no problems.
I bought a used 206 Ultra Limited last year. The salesman didn't really give me much help as to what all the features were. I soon found out that I knew more than he did. I checked my coolant reservoir a couple of times and found it to be a bit low when I thought it was running a bit different. A couple of months ago, right before Thanksgiving, I noticed a puddle of coolant under the bike after I had parked it for a short time. I have the extended warranty and took it to my dealer. They checked it and said it had been overfilled. They didn't charge me but I know I didn't overfill it. So what I'm trying to say is that I'm not quite sure about the "wet head yet. Love your videos, I'm learning a lot about my bike and the 103 in it.
On my 2012 ultra limited, I run a dual fan oil cooler, remote filter, and jug fans. I live in Texas and ride a lot in the southwest. Runs nice and cool. I completely rebuilt the bike in 2022 instead of buying a new one. Did not want tc heads. I'm glad I did that. Now I have exactly what I want for a lot less money. Ride safe, everyone!!!
Yes I own one and confirm it is much cooler to ride on hot days. I also own a 103HO that has limitations in heavy traffic so bring on the twin cooled engines in my opinion.
Thanks for sharing, I've got a future video coming on that twin cam and why it's so dang hot. They were running those things so lean out of the box they were on the verge of melting down. Honestly quite impressive they actually ran starving for fuel so bad.
I love my Tri Glide. I also added Love Jugs formore cooling. The fans run after the bike shuts down after a long ride normally, but when I kick in the Love Jugs fans, the internal fans don't keep running after shutting down.
My2cents...I will have to beg to differ with you on the ability of the bike to run without the water pump ect... lots of us have been doing high compression builds...to the point compression release are required or extremely helpful to save the starter/battery ect. You can run as far as you need to at normal speeds ... for example ...one of my bike was a 96ci took it out to 107 port polished everything and everything thing else ... standard oil pump ... no oil cooler...it did require compression releases ...did parade duty no problem ... can't see where it would be a problem except for warranty if they knew ...yall have a good one ... thanks for the content...
I just bought a used 2019 Ultra and love it. I have been a Harley customer since 1975. This is my first experience with liquid cooling. I live in Phoenix AZ and need all the cooling I can get.
I own a 2014 Ultra Limited and love the twin cooling system and as a plus I run Amsoil 100% synthetic base stock oil in all three holes which brings my engine temp down 12 more degrees and more compression. Now that's what I call COOL!!!!.
Just got home from a 4300+ mile trip to the Gaspe Peninsula. As we we leaving from New Brunswick, the check engine light and temp light came on after about 7 miles on a cool morning. Since the town we stayed in had decent resources, we turned around and waited for the Canadian Tire to open, and while we waited, had a quick look at the coolant overflow tank, which showed low level. So we bought a jug of coolant, topped off the tank, and headed back to the moose-infested riding day, which was beautiful--no issues. Next morning, took off again, and just before our first gas stop at about 180 miles, the temp and CEL came on again. Had a look at the coolant tank again, which was full to the top this time. So, we drained out enough to get it back to the full line, and then took off again, without issue. Next morning, both lights came on again after about 3 miles, and from then on for the next 1000+ miles home, both lights were on within a few miles of every startup, and never again went off. Along the way, I forced the fans to kick on a few times, just to see if any heat would come out of the lower fairing vents--ambient air only, every time, so yeah, the pump was shot. Never leaked a drop, and never ran poorly, and after reading several real-world accounts like this before making our way home, we soldiered on. 90+ degree heat, Chicago traffic, road construction, rain, and heavily loaded 2-up, the bike just didn't seem to care. Mind you, I made sure to coast with the clutch in when slowing down a lot, tried my best to not let it idle very long, activated the EITMS, ran the best fuel I could get, avoided full throttle, kept the speeds in check (70 and below, except when passing big trucks). I'm going to pick up the new pump upgrade kit this morning in about an hour, and wanted to share this story to hopefully help others who might overreact when this happens to them. 2014 FLHTK, 62000+ miles as of last evening. YMMV
Love my 2015 ultra limited ride two up in the pacific northwest with no issues of power loss from heat. Pulls every grade from the coast range to Mt Hood like a champ. Such a comfortable ride. Enjoy your content hell helpful.
Me and my 02 FLHRCI I've been riding since 11/01 are joined at the hip. No coolers of any kind. Bike just hums along beautifully mile after mile and year after year. I see guys on Ultra's and I always think glad I'm not cleaning that thing. Basically, "mow and blow" cleaning keeps my rig looking like new after all these years.
I haven't mounted my oil radiator yet on my 2000 heritage due to a defect in the construction in my opinion, too narrow channels in the transition between hose connection and adapter / radiator. The channels from oil pump to filter are nearly 8 mm but the connection is only 6 mm, a bit much considering that my bike has a high flow pump and a better camplate with greater flow installed, i have to change some parts first and also i had to leave the adaptor to a friend that can help me by welding on some more material so i can drill out holes and thread them for larger couplings before mounting. A side-mounted that i bought is also preferred instead of a central-mounted one that obstructs air flow, there are low-mounted solutions, but there you have the splash from the front wheel instead.
I own the twin cooled and major reason why I picked the Road Glide Ultra over the special. If I’m spending 30 grand I want the best cooling possible. Well done on your explanation 👍
From what I understand - and I’m no expert, as the newest bike I’ve owned is my current ‘74 shovelhead - is this: panheads run cool, shovels kinda hot, evos run cool, twin cams run hot as hell, and Milwaukees run fairly cool. So I can see the reasoning to try and cool down the twin cams, particularly the heavy touring bikes.
Ironically on the Twin Cooled bikes they didn't do it for emissions or performance, it was purely rider comfort. Although they could of put some compression in it for power with the cooler heads.
I just bought a new Tri Glide a month ago. I have no problem with the liquid cooling on my bike. Those engines need all they can get to keep cool. I have a two year warrentee on the Trike so I am not going to worry about it for now. Personally I think it is cool when you stop, turn off the engine and hear fans still running to cool down the liquid.
I have a 2016 road glide ultra that has the liquid cooling system. I like it very well but I did have the water pump to go out. I replaced it and upgraded to the m8 water pump which is more durable and beefy. I’ve had no problems since.
I have a 2014 ultra-limited twin cooled bike I love it no problems I just have the dealer service it . It does have a shut switch that kills the rear cylinder when you stop. You can disable that feature.
I am still on the fence with the whole cylinder shut down thing. GM and Dodge have hell with it on their vehicles, I have a truck that it's disabled on. On a Harley it would have literally be in stop and go traffic in extreme situations for me to use it.
I think Harley Davidson should've used a liquid cooling on the cylinders also. They can put fins on the liquid cooled engine and make it look more like their air cooled engines. In fact some of the Japanese motorcycle manufacturers have done that. I think it was Honda in the 80s that said they left fins on her liquid cooled engines for two reasons. The first was the look. The second was it allowed them to run a smaller radiator. And I agree with you the big oil coolers on the newer softails could be replaced by a radiator.
I've been saying that same thing for years! Kawasaki, Yamaha, Suzuki and Honda have done that same thing for years! Kawasaki and Honda even went as far a single crank pin with over head cams they loped very very close to a Harley. Enough that Harley tried to patent the sound which was denied. Honda went back to dual crank pins which is more efficient but the dual crank pin sounds raspy to me. Kawasaki still uses the single crank pin but the new 52 degree 1700 vulcan motor just doesn't sound as close as it used to with the 1500 and 1600. The 900 sounds decent but it's not nearly the sound they used to get with the bigger inch Kawi's.
I feel the same way .I have a 2003 V Rod with 140,000 and never had a issue with the cooling system. I have no issues with Harley adding a complete cooling system. Mind you I would never own a new Harley lol Used when they drop under the 15g mark
Hello, I own a 15 Ultra and the cooling pump just went out at 21900 mi. I’m replacing it myself. The instructions are good except for where to move the wiring and plugs that the fans plug into. I have viewed the videos where there has been trouble getting the 2 black color screws out at the bottom of the lower fairings. I got mine out with no trouble, but went easy and slow using hand tools. Wouldn’t recommend using any kind of power drive tool. Harley used a lot of blue thread locker on them. Before reinstalling them I tapped out the inserts just enough to remove thread locker inside them. If you don’t, the screws are tight going back in. I’m going to use a small drop of blue thread locker about midway of the screws before installing them.
I just came across this video 2 yrs after its debut. I own a 2015 Road Glide CVO now with a 117” Stage 4 upgrade since I hit 95K miles. My bike currently has 137K miles since new. I’m the original owner. I’m now on my 3rd liquid cooled pump as of last weekend. The original one lasted 76K miles. It was replaced under extended warranty with the new and “improved” version. Which lasted 61K miles until last weekend. After my dealership installed my 3rd liquid cooler the mechanic took it for a test ride and immediately returned back to his shop after hearing transmission noises. Turns out the bolts holding the transmission together loosen over time allowing all the transmission fluid to drain out from its seal. So my bike remains at the dealership waiting on parts, as I wait for another huge repair bill since I’m no longer under extended warranty. It’s times like this I hate being a beta-tester for HD, since it’s now on my dime.
@@GixxerFoo so I pulled the trigger and bought a 2020 FLHTK with 4450 miles on it . May as well say it's brand new. Thanks again for all your great videos!!
Thanks! Will do! Twin Cooling was much needed on the Harleys, it makes a big difference in the heat you feel. Although your wallet feels the cost difference on the Twin Cooled models.
@@GixxerFoo it is a 2014 and has about 29k on it. I need to check the water pump as it seems like the EITMS kicks on with very little ride time. I think it is designed to kick on around 270°F cylinder temp. If I listen closely, I can sometimes hear the radiator fans kick on but they are very quiet.
@@1957eberhart I gotta budget for a tuner before I can do that. It has slip-ons but I do want to get an intake, delete cat, and tune. Probably just do an fp3.
Harley did something similar years ago. My XR1200 has oil cooled heads with a small oil cooler mounted on the left side. This allowed higher compression on the XR compared to the other 1200's.
I’ve got a 2014 Twin Cooled Mt Rushmore CVO Limited. I have 15000 miles on it and have never had any trouble with it. I have a K&N filter element in the SE air filter housing and a complete “cat less” FullSac exhaust system. I’m also running the XEID plug and play fuel enricheners. I have never had a situation in traffic where my engine got really hot. In fact, my radiator fans hardly ever kick on.
I have a 15 limited. It still puts off a lot of heat. Even after getting rid of the cat. The biggest down side to it is you can't remove the lowers on hot days. It's been in the upper 90's here the last couple weeks and hitting the low 100's starting Sunday.
There are two versions of the m8 both twin cool one uses coolant and radiators the other oil which is linked to the oil system both cool the exhaust area in the heads
I had a 17' RGU twin cooled M8..definately ran cooler during hot days..unfortunately the M8 motor was a flop..too many issues..really did like that bike 😣 ride safe
Two years ago I was in San Francisco and my water pump went out at sixty thousand miles. I rode it to Seattle and replaced it with the updated brushless pump like the N8 have no problems at eighty one thousand miles. 2014 limited.
@@rgh622 Yes I rode from san Francisco to Seattle with the water pump not working . I deleted the cat at ten thousand miles so my motor runs a lot cooler and the passenger right foot does not get fried.
Ive been enjoying my twin cooled 2014 ultra limited. I came from a switch back. Both had an intake and V&H propipe. But I was surprised the big ultra felt more peppy than my much lighter switchback.
Nice you got the latest model, a friend of mine just traded his 2018 Street Glide for a Twin Cooled '21 Ultra. Lol now we get to go back and build his Ultra like we had his Street Glide, he had a lot of goodies on the Street Glide.
My buddy had a 2014 street glide that shut the rear cylinder down when it got hot, it had lower fairings but I think only the big Ultra classics had the liquid cooled heads. My 12 street glide womped his 14.
I was never really sold on that "parade mode" with the rear cylinder shut down feature. It's a great concept, I just wasn't a huge fan of it after seeing the carnage from GM trucks with the cylinder shut down lol.
@@GixxerFoo agree, that's about the stupidest thing ever, it's obvious they got global warming assclowns coming up with ways to slow down fake global warming but don't get the concept of how an engine truly works. Just like the moron that came up with the EGR for diesel engines, I did the delete on mine and I'm getting 10 to 12 mpg more and it runs better.
Hey Gixxer hope all is well, yah I run a 2016 Limited and have no complaints at all. I get the cooling adds extra parts and earlier models had issues but you can put an M8 pump and t stat on if you want to upgrade the system and it's not to expensive for piece of mind. But so far so good no complaints here. And on the internet you can find the manufacturer of the Harley coolant Ok here it is Peak Global Lifetime 50/50 (from another post and he got his info from the MSDS sheet) and save some cash there 20 at HD or 9 form Napa. Love all the vids brother keep them coming. R,O
I have a 2015 ultra road glide w/ 32000 miles the water pump went out had to ride 40 miles to get back home was 80 deg outside didn`t have any trouble on the way home replaced pump with upgrade m8 water pump. had to reroute some hoses and put on a new bracket but all went well! have not had any problem so far.
The oil cooler was sacrificed to make room for the coolant pump. An oil cooler kit by DK customs (Jams) would add a real benefit to running cooler and an added benefit of routing oil through the oil filter before going through the cooler, unlike the stock oil cooler (on oil/air cooled engines) that runs the unfiltered oil through the cooler then through the filter. Something to think about for the standard M8.
Great point! I was surprised they would run oil unfiltered through the cooler on the M8, that's just asking for trouble. It's a shame they keep the oil cooler on the twin cooled bikes since the rest of the engine is still oil cooled.
I note the engine temp on my 2014 ultra limited is a touch higher than a none twin cooled equivalent, I have the latest Pierburg pump upgrade and feel the lack of an oil cooler is a factor in this.
I would like to see Harley develop a water cooled, OHC, not pressed crank motor. I think they have iterated the current motor as far as possible. Great explanation!
Thank you! Kawasaki and Honda made single pin crank overhead cam cruisers that appeared air cooled and were very reliable. They even sounded like a Harley with the single crank pin. Lol Harley tried to patent their sound cause of it.
Things done, mainly the higher compression, is what produces the higher output........they were allowed to do those things because of the head cooling hmmmmm radiators in the lower fairings......air goes thru radiators to cool the coolant thru heat transfer, the air pulls away the heat.........then this hot air is directed onto the riders legs? might be nice for winter riding BTW never knew of this
I own several Harleys of early to late years, none liquid-cooled, I was looking to buy a revolution (water-cooled) but they stopped production. don't know why maybe you could tell us. my point, why discontinue a water-cooled bike, only to continue a partially cooled bike. any Harley set up right, (a good tuner, intake, & exhaust) will run a lot cooler and better, even my Panhead & shovel run cooler than any twin-cam or Evo I own. EPA has made things detrimental to HD's v-twins, so just bring back the water-cooled bikes. tks, keep em running!
Yeah I lost the water pump on my 2016 FLTRU on the way back from sturgis last year. However mine never got the upgraded pump as I never had an issue with it until that trip. Which shocks most people that I got the life out of it that I did? Happened at about 37,000 miles on mine. Got the new larger pump now and was done on my ESP which lmao is about one of three things harley would warranty on my bike because I work/upgrade shit all the time. I will say the couple break downs I had paid for the ESP so I did not lose any money on the ESP but would have gladly if I could have. I hate breakdowns. I did do as you said took an easy cruise to the local dealer an hour and half away. No issues to report from that and now currently 42,000 miles on it.
So I love ur videos absolutely amazing! However I wish u would have went into more detail about how it actually works and really get into it maybe a future video?
How does everyone feel about not having an oil cooler on these models ? Is anyone under the impression the oil temps get hotter than on non dual cool models ?
I have a 2021 RGL twin cooled, most of the time runs great! with that said, I have a problem with heat way hot!! on the right side have been told its the "cat" have you done a video on that yet?? if not your thoughts ?? new header?? if so tune??
Hi I’m Rick Ben ridding sence 1957 my first harley was a 48 pan then a 58 pan done some work on it fly pistons shovel intake valve’s 412 andrews cam lake injector carb wired distributer full advance it ran great and it was a chopped down chopper with a springer. Now I’m working on a 2008 Dina had it for awhile turned it into a trike didn’t like the ride so it’s back to two wheels. Im building the Moter to a 107 with bored 103 cyenders wet heads from 103 ported and built from short block Charleys 10.5 compression 222 woods cam cow k1000 radiator twin fans vance and hinze staggered exaust with crossover. Vance and hinze tuner 3 so what do you think.oh I😮I have no problem with a radiator with two fans setting out front comfort is my goal I’m 84 still working full time as a auto parts driver.
I own a 2014 ultra Limited with 103 twin-cooled motor I've been looking through your videos to see if you mentioned a S&S kit/ crate motor that would be suitable for this bike maybe you can refer me back to an old video would be great thanks
All the crate engines right now on the aftermarket are oil cooled, Harley-Davidson has 110 crate motors that are twin cooled. They really are missing out on an entire market there.
I bought love jugs for my 117 twin cam. Cylinder Temps use to jump up to 306 degrees in traffic. Now they hover around 257 degrees in traffic during warm days around 80 degrees out. But I would like to see a full water cooled engine for all softail models in the near future.
I have a 2014 limited and had the upgrade pump put on it and i have 54.050 miles on it and the pump was changed at 30.000 and no problems no where on the bike at 54.050.
I almost wish I hadnt got rid of my hotrodded nighster, these bigger bikes have major issues in all of them. it took me 9 months just to source the parts for my compensator job on my 09 heritage now its so damn hot gotta wait til fall to work on it so I dont get heat stroke lol
I’m adding water cooled heads to my 2008 dina using a m8 water pump and k1000 3 core radiator with 3 cors and two fans pulling air 107 inch 10.5 compression ported heads woods 222 cam and also Jim’s rear cylinder head fan
First Off Thank You For Your Knowledge... and also Your Honesty... I own a 2015 CVO Road Glide Ultra Twin Cooled. As for Heat I live here In Phoenix Arizona...And yes it's Hot Here sometimes over 115 Degrees. For me I don't ride if it's over 100. Even if it's 100 Degrees outside my bike Runs like a Deer with its ASS ON FIRE.... Just Ride it... Don't Complain About How Hot it is... Man UP....
Why not split the radiators? Just re-arrange the hoses. Harley does not offer oil coolers for these models, due to the cooling system taking all the forward area. Harley engineers should have considered this during the design stage. Im probably not the first to consider this practical upgrade. Ken
You did not answer my question about splitting the raditors. I presently have a 2015 Ultra Limited. Love the bike. It has 42,000 with no issues yet, except for the junk compensator, which I swapped for a sprocket. The rear wheel has rubber cushions and will take any shock load. Also went with the Hayden tensioner, execelent. A little rattle in the primary due to the clutch pack chattering in the basket. Liveable. I still think that by splitting the radiators would accomplish removing heat from the engine by cooling both the coolant and the oil. Doesn't anybody ever say "why not" or "how come"? Gotta think outside the box c'mon man.
7:00pm. I have a twin cooled CVO 2015. It had the early thermostat problem and now, at 28k miles, I'm getting the over-heating indicator again. Thermostat?
tengo una ultra limited 2019 114, 32.000 km., falló la bomba de agua.-...., la cambié y al cabo de 5.000 km ha vuelto a fallar.... (en menos de 7 días)..... no sé porque puede suceder....
I ride a 2021 Ultra and my complaint is when it's hot out 90 degrees or more the airflow from the radiator flows right onto the calf of my leg. The right side being the worst. It gets to the point where it's unbearable! I've installed Design Enginering's heat shield insulators which helped a lot, but the air flow from the radiator is the worst! It would be nice if someone made an aftermarket inner shield for the lowers that re-routes the radiator heat below the bike.
2015 Ultra Limited Low, purchased new. So far do problems what so ever. Only downside is 𝗰𝗮𝗻'𝘁 do a whole bunch to the engine as far as horsepower/torque goes. 🤷🏾♂️
I own a 21 triglide and I like the twin cooled my complaint is no oil cooler and no temperature gauge I plan on adding a ultracool oil cooler and plan on changing gauges to Dakota Digital
Did you do the upgrades?…….I’m thinking about doing the same with my 15’ FLHTKL………I’m just not sure about the fairing modifications that seem to require cutting the left lower fairing up to fit the cooler. Was wondering if there’s a way to avoid that?……..maybe relocating the oil filter to behind the primary like with a DK customs oil relocation kit? Not sure how to and which way to jump……..
You are making me think that "twin cooled" really means THREE methods of cooling the engine are being used simultaneously. (1) old fashion air cooling (2) oil cooling with an oil cooler located to be hit by wind (3) liquid coolant cooling that has a radiator set-up . Am I getting you wrong? Thank you.
What is your opinion of the Twin Cooled Harley-Davidson engines?
I think the M8 will be the last of the air cooled built in mass. The pan American revolution engine will likely start crossing platforms. The sportster died in Europe due to their emissions. Great place for the revolution to debut
I love my 2017 road glide ultra twin cooled
I just finished all upgrades to my 14 SGS 103 to 110. It’s done! All air cooled with love jugs. Runs just as I hoped it would. I pull a trailer and wanted low end power. It pulls like a train😊. Anyhow, if I were in market, I would prefer a total water cooled scooter like the challenger. I hope H-D will offer a full dressed challenger… challenger. I would seriously consider it. Hell, I would buy a challenger if it had lower fairings with speakers along with the tour pack.

It doesn’t work, my 2014 cooling system failed twice and most people I know with this same setup have had water pump failures, right up to present day. It’s a similar situation to hydraulic clutches, Harley just can’t get them to work. They finally gave up on the hydraulic clutches and should give up on the liquid cooling.
A couple of years ago we were on a 2 week crosscountry trip. One RG, my Ultra Ltd and a 2014 CVO Ltd twin cooled. All three bikes had Trask turbos installed. All of us were pulling 300 lb camper trailers. The second day in on a Sunday, the CVO water pump failed. We were an hour or so to a dealer so we headed there, keeping an eye on temps but of course they were closed. We were sitting in the parking lot trying to decide what to do when a bike pulled in and asked if we were ok. Told him our situation and he said "just ride it, wont be a problem". We were a little skeptical until he told us he was the head mechanic at another HD shop. We didnt have much choice so we carried on, again watching out for temps and knocking. Following day we tried to find new water pump but they were out of stock because a lot of people were having failures. Long story short, we continued our 2 week trip and put about 5000 miles on the CVO without the water pump working with no issues at all. Got home and replaced the old pump with the new upgraded pump. Bike is still running like a champ.
Bought a 2014 Ultra Limited brand new. 40,000+ miles on it now, no coolant or water pump problems so far. Traded in a Gold Wing for it. I do have to admit, the Gold Wing was almost as reliable as the Harley. But not quite.
I own a 15 CVO RG Ultra that is twin cooled. I live in western Arizona where Temps can be very extreme. I love the liquid cooling simply because of being in situations (city traffic and lights) when my cooling fans engage and I know my motor is in need cooling and traffic doesn't permit it. Its a nice advantage and I'm at 75,000 miles and I've never had an issue with the cooling system 👍👍👍
That's quite a few miles! That bike doesn't sit much at all, glad to hear it's working well for you out there!
2014 Ultra Limited - H2O Pump went out @ 30k (P1019). Was 100+ miles away, called mech said it was fine to ride home, just keep it under 3k RPM's. $500 later = fixed ($300 upgraded part / $200 labor).
There was a recall for later Rushmore models and if you find that your H2O pump fails (and it will) do not replace it with OEM, get the upgraded 2017/2018 part.
As to selling these twin cooled bikes to the "look at me ppl", have owned & ridden many HD air/oil-cooled bikes over the years & at my age now can afford + appreciate my rolling couch - I still ride in the rain / heat / etc... but now do it in style and comfort!
I bought a 2014 ultra limited new and love the twin cooling. Zero issues so far.
I live in Perth West Australia 🇦🇺 and rode my 03 fatboy on 42 degree Celsius for 600km no power loss and no issue of what so ever, no need for extra headaches of radiator, thermostat,water pump, coolant and extra $$$ in maintenance
Ride safe everyone
Yep. Rode north from Blue Mountains for 2000km middle of summer on my stock Sporty. No issues. I have nothing against water cooling. But everything I own is air cooled. Even my car, which my brother drove from Sydney to Perth and back in 45°C days through summer.
I had a 2007 Street Glide with the 96 twin cam and then purchased the 2015 Ultra Limited 103 twin cooled and now have a 2021 Ultra Limited 114 twin cooled. To be honest with you I didn't give much thought about it. I didn't feel that much difference between all three of my bikes. I just installed the Harley Davidson cool fan a couple of weeks ago will see if it helps with heat. Thank you for sharing the video.
When my 15 Limited water pump failed at 8k I still road it in the heat for almost a month before I brought it in for the new #p/n pump and so far so good currently at 40k no problems.
I bought a used 206 Ultra Limited last year. The salesman didn't really give me much help as to what all the features were. I soon found out that I knew more than he did. I checked my coolant reservoir a couple of times and found it to be a bit low when I thought it was running a bit different. A couple of months ago, right before Thanksgiving, I noticed a puddle of coolant under the bike after I had parked it for a short time. I have the extended warranty and took it to my dealer. They checked it and said it had been overfilled. They didn't charge me but I know I didn't overfill it. So what I'm trying to say is that I'm not quite sure about the "wet head yet. Love your videos, I'm learning a lot about my bike and the 103 in it.
On my 2012 ultra limited, I run a dual fan oil cooler, remote filter, and jug fans. I live in Texas and ride a lot in the southwest. Runs nice and cool. I completely rebuilt the bike in 2022 instead of buying a new one. Did not want tc heads. I'm glad I did that. Now I have exactly what I want for a lot less money. Ride safe, everyone!!!
Yes I own one and confirm it is much cooler to ride on hot days.
I also own a 103HO that has limitations in heavy traffic so bring on the twin cooled engines in my opinion.
Thanks for sharing, I've got a future video coming on that twin cam and why it's so dang hot. They were running those things so lean out of the box they were on the verge of melting down. Honestly quite impressive they actually ran starving for fuel so bad.
I have a 2016 Ultra Limited with twin cooling. Have 20K miles. Have had no problems. Easy to check level and add coolant if necessary.
I love my Tri Glide. I also added Love Jugs formore cooling. The fans run after the bike shuts down after a long ride normally, but when I kick in the Love Jugs fans, the internal fans don't keep running after shutting down.
I seem to learn something new from your videos. Never even thought about the twin cooled bikes.
That's awesome to hear, twin cooled bikes are a very interesting concept and I was shocked when Harley actually did it.
My2cents...I will have to beg to differ with you on the ability of the bike to run without the water pump ect... lots of us have been doing high compression builds...to the point compression release are required or extremely helpful to save the starter/battery ect. You can run as far as you need to at normal speeds ... for example ...one of my bike was a 96ci took it out to 107 port polished everything and everything thing else ... standard oil pump ... no oil cooler...it did require compression releases ...did parade duty no problem ... can't see where it would be a problem except for warranty if they knew ...yall have a good one ... thanks for the content...
I just bought a used 2019 Ultra and love it. I have been a Harley customer since 1975. This is my first experience with liquid cooling. I live in Phoenix AZ and need all the cooling I can get.
That twin cooled motor will shine in that AZ climate, friend of mine just got a twin cooled bike and he loves it!
I own a 2014 Ultra Limited and love the twin cooling system and as a plus I run Amsoil 100% synthetic base stock oil in all three holes which brings my engine temp down 12 more degrees and more compression. Now that's what I call COOL!!!!.
That's awesome to hear! Amsoil is really all I use myself too in my bikes and trucks.
Just got home from a 4300+ mile trip to the Gaspe Peninsula. As we we leaving from New Brunswick, the check engine light and temp light came on after about 7 miles on a cool morning. Since the town we stayed in had decent resources, we turned around and waited for the Canadian Tire to open, and while we waited, had a quick look at the coolant overflow tank, which showed low level.
So we bought a jug of coolant, topped off the tank, and headed back to the moose-infested riding day, which was beautiful--no issues.
Next morning, took off again, and just before our first gas stop at about 180 miles, the temp and CEL came on again. Had a look at the coolant tank again, which was full to the top this time. So, we drained out enough to get it back to the full line, and then took off again, without issue.
Next morning, both lights came on again after about 3 miles, and from then on for the next 1000+ miles home, both lights were on within a few miles of every startup, and never again went off. Along the way, I forced the fans to kick on a few times, just to see if any heat would come out of the lower fairing vents--ambient air only, every time, so yeah, the pump was shot.
Never leaked a drop, and never ran poorly, and after reading several real-world accounts like this before making our way home, we soldiered on.
90+ degree heat, Chicago traffic, road construction, rain, and heavily loaded 2-up, the bike just didn't seem to care. Mind you, I made sure to coast with the clutch in when slowing down a lot, tried my best to not let it idle very long, activated the EITMS, ran the best fuel I could get, avoided full throttle, kept the speeds in check (70 and below, except when passing big trucks).
I'm going to pick up the new pump upgrade kit this morning in about an hour, and wanted to share this story to hopefully help others who might overreact when this happens to them.
2014 FLHTK, 62000+ miles as of last evening.
YMMV
Love my 2015 ultra limited ride two up in the pacific northwest with no issues of power loss from heat. Pulls every grade from the coast range to Mt Hood like a champ. Such a comfortable ride. Enjoy your content hell helpful.
Thank you! That Ultra is one sweet machine for running down the highways where you're at, beautiful country out that way.
I own a 2019 Ultra Limited twin cooled 114….. I love mine…. Ride safe 🇺🇸
Junk
They are really nice bikes on the long haul, they seem to have the issues worked out now they had in the 2017 model year.
You won't love it when the Oil pump fails.
Crap at best .
@@lindacruz7238 agreed and dealing with coolant fuck that lol
I have a 2020 ultra limited and I love it. Its all black and the twin cooling is definitely nice on hot days.
Me and my 02 FLHRCI I've been riding since 11/01 are joined at the hip. No coolers of any kind. Bike just hums along beautifully mile after mile and year after year. I see guys on Ultra's and I always think glad I'm not cleaning that thing. Basically, "mow and blow" cleaning keeps my rig looking like new after all these years.
My 2014 rode from south Dakota to Miami with bad water pump no problem
I haven't mounted my oil radiator yet on my 2000 heritage due to a defect in the construction in my opinion, too narrow channels in the transition between hose connection and adapter / radiator. The channels from oil pump to filter are nearly 8 mm but the connection is only 6 mm, a bit much considering that my bike has a high flow pump and a better camplate with greater flow installed, i have to change some parts first and also i had to leave the adaptor to a friend that can help me by welding on some more material so i can drill out holes and thread them for larger couplings before mounting. A side-mounted that i bought is also preferred instead of a central-mounted one that obstructs air flow, there are low-mounted solutions, but there you have the splash from the front wheel instead.
I own a 2016 Road Glide Ultra and I enjoy having a twin cooled engine, especially on the long road trips.
Right on! When you're on the bike for hours a time you really notice it there!
I own the twin cooled and major reason why I picked the Road Glide Ultra over the special. If I’m spending 30 grand I want the best cooling possible. Well done on your explanation 👍
Have a 19 Triglide and twin cooling is unnoticeable but more comfortable to ride on a hot summer day. Power stays there when needed without fail.
Your absolutely right.
I have a 2015 Ultra Limited. I love the bike. There are times when I can feel the heat coming off of the radiators.
I got a 2014 ultra limited thats twin cooled and have had no issues bike runs like a champ
Thanks for the info. I always wondered how the twin cooling worked.
No problem! It's a really interesting system, I seriously wonder if they will expand on it as regulatory emissions increase.
From what I understand - and I’m no expert, as the newest bike I’ve owned is my current ‘74 shovelhead - is this: panheads run cool, shovels kinda hot, evos run cool, twin cams run hot as hell, and Milwaukees run fairly cool. So I can see the reasoning to try and cool down the twin cams, particularly the heavy touring bikes.
Ironically on the Twin Cooled bikes they didn't do it for emissions or performance, it was purely rider comfort. Although they could of put some compression in it for power with the cooler heads.
I just bought a new Tri Glide a month ago. I have no problem with the liquid cooling on my bike. Those engines need all they can get to keep cool. I have a two year warrentee on the Trike so I am not going to worry about it for now. Personally I think it is cool when you stop, turn off the engine and hear fans still running to cool down the liquid.
I have a 2016 road glide ultra that has the liquid cooling system. I like it very well but I did have the water pump to go out. I replaced it and upgraded to the m8 water pump which is more durable and beefy. I’ve had no problems since.
I like mine. 2015 ultra limited. Upgraded the pump last month.
I have a 2014 ultra-limited twin cooled bike I love it no problems I just have the dealer service it . It does have a shut switch that kills the rear cylinder when you stop. You can disable that feature.
I am still on the fence with the whole cylinder shut down thing. GM and Dodge have hell with it on their vehicles, I have a truck that it's disabled on. On a Harley it would have literally be in stop and go traffic in extreme situations for me to use it.
From what I understand,the cylinder shut down is for rider comfort,doesn't do anything to cool off motor.
I own a 19” Road Glide ultra and love it! Best bike I have ever owned
Yes sir! If I ever get a touring bike it will be a ultra limited and I would shoot for a 2016 with lower mileage. As always thx for the info!
I think Harley Davidson should've used a liquid cooling on the cylinders also. They can put fins on the liquid cooled engine and make it look more like their air cooled engines. In fact some of the Japanese motorcycle manufacturers have done that. I think it was Honda in the 80s that said they left fins on her liquid cooled engines for two reasons. The first was the look. The second was it allowed them to run a smaller radiator. And I agree with you the big oil coolers on the newer softails could be replaced by a radiator.
I've been saying that same thing for years! Kawasaki, Yamaha, Suzuki and Honda have done that same thing for years! Kawasaki and Honda even went as far a single crank pin with over head cams they loped very very close to a Harley. Enough that Harley tried to patent the sound which was denied. Honda went back to dual crank pins which is more efficient but the dual crank pin sounds raspy to me. Kawasaki still uses the single crank pin but the new 52 degree 1700 vulcan motor just doesn't sound as close as it used to with the 1500 and 1600. The 900 sounds decent but it's not nearly the sound they used to get with the bigger inch Kawi's.
I feel the same way .I have a 2003 V Rod with 140,000 and never had a issue with the cooling system. I have no issues with Harley adding a complete cooling system. Mind you I would never own a new Harley lol Used when they drop under the 15g mark
Hello, I own a 15 Ultra and the cooling pump just went out at 21900 mi. I’m replacing it myself. The instructions are good except for where to move the wiring and plugs that the fans plug into. I have viewed the videos where there has been trouble getting the 2 black color screws out at the bottom of the lower fairings. I got mine out with no trouble, but went easy and slow using hand tools. Wouldn’t recommend using any kind of power drive tool. Harley used a lot of blue thread locker on them. Before reinstalling them I tapped out the inserts just enough to remove thread locker inside them. If you don’t, the screws are tight going back in. I’m going to use a small drop of blue thread locker about midway of the screws before installing them.
I just came across this video 2 yrs after its debut.
I own a 2015 Road Glide CVO now with a 117” Stage 4 upgrade since I hit 95K miles.
My bike currently has 137K miles since new. I’m the original owner.
I’m now on my 3rd liquid cooled pump as of last weekend. The original one lasted 76K miles. It was replaced under extended warranty with the new and “improved” version. Which lasted 61K miles until last weekend. After my dealership installed my 3rd liquid cooler the mechanic took it for a test ride and immediately returned back to his shop after hearing transmission noises. Turns out the bolts holding the transmission together loosen over time allowing all the transmission fluid to drain out from its seal.
So my bike remains at the dealership waiting on parts, as I wait for another huge repair bill since I’m no longer under extended warranty.
It’s times like this I hate being a beta-tester for HD, since it’s now on my dime.
Perfect timing for this video because i'm actually looking at buying a newer or brand new Harley. As always great information!!!
Thank you! They really seem to have the bugs worked out now, I personally feel like with the new CEO quality has improved as well.
@@GixxerFoo so I pulled the trigger and bought a 2020 FLHTK with 4450 miles on it . May as well say it's brand new. Thanks again for all your great videos!!
Twin cooling is alright by me! Again another informative video bruddah, keep up the great work and keep them coming!!
Thanks! Will do! Twin Cooling was much needed on the Harleys, it makes a big difference in the heat you feel. Although your wallet feels the cost difference on the Twin Cooled models.
The FXS lowrider of 77 had an oil cooler std looked kool
Just got one recently. Guess we will see how it holds up.
That's awesome! The water cooled heads make a huge difference.
@@GixxerFoo it is a 2014 and has about 29k on it. I need to check the water pump as it seems like the EITMS kicks on with very little ride time. I think it is designed to kick on around 270°F cylinder temp. If I listen closely, I can sometimes hear the radiator fans kick on but they are very quiet.
@@huntridesail delete the cat and it will run a lot cooler.
@@1957eberhart I gotta budget for a tuner before I can do that. It has slip-ons but I do want to get an intake, delete cat, and tune. Probably just do an fp3.
Harley did something similar years ago. My XR1200 has oil cooled heads with a small oil cooler mounted on the left side. This allowed higher compression on the XR compared to the other 1200's.
That XR was very impressive Sportster engine, I wish more of that motor made into the regular Sportster.
I’ve got a 2014 Twin Cooled Mt Rushmore CVO Limited. I have 15000 miles on it and have never had any trouble with it. I have a K&N filter element in the SE air filter housing and a complete “cat less” FullSac exhaust system. I’m also running the XEID plug and play fuel enricheners. I have never had a situation in traffic where my engine got really hot. In fact, my radiator fans hardly ever kick on.
I have a 15 limited. It still puts off a lot of heat. Even after getting rid of the cat. The biggest down side to it is you can't remove the lowers on hot days. It's been in the upper 90's here the last couple weeks and hitting the low 100's starting Sunday.
There are two versions of the m8 both twin cool one uses coolant and radiators the other oil which is linked to the oil system both cool the exhaust area in the heads
I had a 17' RGU twin cooled M8..definately ran cooler during hot days..unfortunately the M8 motor was a flop..too many issues..really did like that bike 😣 ride safe
The 17's being that first year had some issues, but it seems like they've got them worked out now.
@@GixxerFoo just my luck..😊
It is always a pleasure to see your videos thanks dude.
When Harley will go 100% liquids cooling on their dinosaurs 😂
Two years ago I was in San Francisco and my water pump went out at sixty thousand miles. I rode it to Seattle and replaced it with the updated brushless pump like the N8 have no problems at eighty one thousand miles. 2014 limited.
Did you ride it, being just air-cooled, from SF to Seattle without issues?
@@rgh622 Yes I rode from san Francisco to Seattle with the water pump not working . I deleted the cat at ten thousand miles so my motor runs a lot cooler and the passenger right foot does not get fried.
Ive been enjoying my twin cooled 2014 ultra limited. I came from a switch back. Both had an intake and V&H propipe. But I was surprised the big ultra felt more peppy than my much lighter switchback.
Recently brought a 2021 ultra limited, not enough km's at the moment to tell, I suppose, but, so far, so good. 🤷♂️
Nice you got the latest model, a friend of mine just traded his 2018 Street Glide for a Twin Cooled '21 Ultra. Lol now we get to go back and build his Ultra like we had his Street Glide, he had a lot of goodies on the Street Glide.
@@GixxerFoo that's what's good about the ultra, strip it down, to a degree, hey presto, you've got a street glide lol.
Love my twin cooled 114! Freaks folks out when I shut it down and the fans are still running :)
That's awesome! Lol that's not something you hear every day from a Harley.
delete the cat and the fans will almost never come on.
@@1957eberhart Thats the first thing I'm going to do when the warranty runs out in october!
My buddy had a 2014 street glide that shut the rear cylinder down when it got hot, it had lower fairings but I think only the big Ultra classics had the liquid cooled heads. My 12 street glide womped his 14.
I was never really sold on that "parade mode" with the rear cylinder shut down feature. It's a great concept, I just wasn't a huge fan of it after seeing the carnage from GM trucks with the cylinder shut down lol.
@@GixxerFoo agree, that's about the stupidest thing ever, it's obvious they got global warming assclowns coming up with ways to slow down fake global warming but don't get the concept of how an engine truly works. Just like the moron that came up with the EGR for diesel engines, I did the delete on mine and I'm getting 10 to 12 mpg more and it runs better.
Hey Gixxer hope all is well, yah I run a 2016 Limited and have no complaints at all. I get the cooling adds extra parts and earlier models had issues but you can put an M8 pump and t stat on if you want to upgrade the system and it's not to expensive for piece of mind. But so far so good no complaints here. And on the internet you can find the manufacturer of the Harley coolant Ok here it is Peak Global Lifetime 50/50 (from another post and he got his info from the MSDS sheet) and save some cash there 20 at HD or 9 form Napa. Love all the vids brother keep them coming.
R,O
I have a 2015 ultra road glide w/ 32000 miles the water pump went out had to ride 40 miles to get back home was 80 deg outside didn`t have any trouble on the way home replaced pump with upgrade m8 water pump. had to reroute some hoses and put on a new bracket but all went well!
have not had any problem so far.
The oil cooler was sacrificed to make room for the coolant pump. An oil cooler kit by DK customs (Jams) would add a real benefit to running cooler and an added benefit of routing oil through the oil filter before going through the cooler, unlike the stock oil cooler (on oil/air cooled engines) that runs the unfiltered oil through the cooler then through the filter. Something to think about for the standard M8.
Great point! I was surprised they would run oil unfiltered through the cooler on the M8, that's just asking for trouble. It's a shame they keep the oil cooler on the twin cooled bikes since the rest of the engine is still oil cooled.
I note the engine temp on my 2014 ultra limited is a touch higher than a none twin cooled equivalent, I have the latest Pierburg pump upgrade and feel the lack of an oil cooler is a factor in this.
I would like to see Harley develop a water cooled, OHC, not pressed crank motor. I think they have iterated the current motor as far as possible. Great explanation!
Thank you! Kawasaki and Honda made single pin crank overhead cam cruisers that appeared air cooled and were very reliable. They even sounded like a Harley with the single crank pin. Lol Harley tried to patent their sound cause of it.
They did way back in 2001. It's called a V-Rod.
@@zf4hp24 I always thought I would see than engine adapted to the balance of the line, but never worked out that way.
Things done, mainly the higher compression, is what produces the higher output........they were allowed to do those things because of the head cooling
hmmmmm radiators in the lower fairings......air goes thru radiators to cool the coolant thru heat transfer, the air pulls away the heat.........then this hot air is directed onto the riders legs? might be nice for winter riding
BTW never knew of this
Had a 2017 Ultra, 2022 RG Special, and 2023 Limited. I like the wet heads best but I live in the Arizona desert and that might taint my opinion some:)
I think the twin cooled bikes were an excellent idea and a step in the right direction!
Nice bike, I'll stick with my 1992 Evo Ultra Glide Classic still going strong. Great channel as always 👍🤘😎🇦🇺
Thank you! Man those Evo bikes are just hard to beat, you get a good strong torque cam in a Evo tourer and it will eat up some miles effortlessly.
66k miles on 2014 FLHTK. Still have not had to replace water pump.
Another great episode. Thanks again for your hard work.
Thank you! I appreciate it!
I own a 2017 ultra classic and I love the water cooled
I’m currently looking at a 2015 CVO Street Glide with twin cooling. It only has 1800 miles basically a new bike. Just not sure about the cooling.
I have a 2015 cvo with the 110 twin cooled motor , I haven't any over heating problem like I did with my previous twin cam cvo
I had 3… now I have a road glide cvo but I loved the twin cooled
I own several Harleys of early to late years, none liquid-cooled, I was looking to buy a revolution (water-cooled) but they stopped production. don't know why maybe you could tell us. my point, why discontinue a water-cooled bike, only to continue a partially cooled bike. any Harley set up right, (a good tuner, intake, & exhaust) will run a lot cooler and better, even my Panhead & shovel run cooler than any twin-cam or Evo I own. EPA has made things detrimental to HD's v-twins, so just bring back the water-cooled bikes. tks, keep em running!
Yeah I lost the water pump on my 2016 FLTRU on the way back from sturgis last year. However mine never got the upgraded pump as I never had an issue with it until that trip. Which shocks most people that I got the life out of it that I did? Happened at about 37,000 miles on mine. Got the new larger pump now and was done on my ESP which lmao is about one of three things harley would warranty on my bike because I work/upgrade shit all the time. I will say the couple break downs I had paid for the ESP so I did not lose any money on the ESP but would have gladly if I could have. I hate breakdowns. I did do as you said took an easy cruise to the local dealer an hour and half away. No issues to report from that and now currently 42,000 miles on it.
Hopefully it keeps on working good for you now, really sucks having the bike down especially in the middle of summer.
@@GixxerFoo yes sir...
had my 05 big bore rebuilt to a 103. I'm putting a oil cooler on it when I take it for its tune. just because.
Oil cooler is never a bad idea, Harley should of done it from the factory years ago.
Very informative. I have a 2015 Ultra Limited and love it.
So I love ur videos absolutely amazing! However I wish u would have went into more detail about how it actually works and really get into it maybe a future video?
Will do, I can definitely cover the flow paths and some temperatures involved with the thermostat.
How does everyone feel about not having an oil cooler on these models ? Is anyone under the impression the oil temps get hotter than on non dual cool models ?
I have a 2021 RGL twin cooled, most of the time runs great! with that said, I have a problem with heat way hot!! on the right side have been told its the "cat" have you done a video on that yet?? if not your thoughts ?? new header?? if so tune??
Hi I’m Rick Ben ridding sence 1957 my first harley was a 48 pan then a 58 pan done some work on it fly pistons shovel intake valve’s 412 andrews cam lake injector carb wired distributer full advance it ran great and it was a chopped down chopper with a springer. Now I’m working on a 2008 Dina had it for awhile turned it into a trike didn’t like the ride so it’s back to two wheels. Im building the Moter to a 107 with bored 103 cyenders wet heads from 103 ported and built from short block Charleys 10.5 compression 222 woods cam cow k1000 radiator twin fans vance and hinze staggered exaust with crossover. Vance and hinze tuner 3 so what do you think.oh I😮I have no problem with a radiator with two fans setting out front comfort is my goal I’m 84 still working full time as a auto parts driver.
I own a 2014 ultra Limited with 103 twin-cooled motor I've been looking through your videos to see if you mentioned a S&S kit/ crate motor that would be suitable for this bike maybe you can refer me back to an old video would be great thanks
All the crate engines right now on the aftermarket are oil cooled, Harley-Davidson has 110 crate motors that are twin cooled. They really are missing out on an entire market there.
I bought love jugs for my 117 twin cam. Cylinder Temps use to jump up to 306 degrees in traffic. Now they hover around 257 degrees in traffic during warm days around 80 degrees out. But I would like to see a full water cooled engine for all softail models in the near future.
I have a 20 road glide ultra and love it!!!
I have a 2014 limited and had the upgrade pump put on it and i have 54.050 miles on it and the pump was changed at 30.000 and no problems no where on the bike at 54.050.
My name is Steven I'd like to know what do you think about the jog coolers
I love my 2019 Limited. It is weird to say that one part of my servicing will be replacing the coolant, but hey...*shrugs*
is there added cost when doing cam swaps and other motor work because of the twin cool heads?
I almost wish I hadnt got rid of my hotrodded nighster, these bigger bikes have major issues in all of them. it took me 9 months just to source the parts for my compensator job on my 09 heritage now its so damn hot gotta wait til fall to work on it so I dont get heat stroke lol
The Sportster is solid reliable, it's hard getting parts right now for everything with all the stuff going on in the world.
Thanks for the great explanation!!
I’m adding water cooled heads to my 2008 dina using a m8 water pump and k1000 3 core radiator with 3 cors and two fans pulling air 107 inch 10.5 compression ported heads woods 222 cam and also Jim’s rear cylinder head fan
I have. 2016 FLHTK and had to change the pump twice, now I have the new M8 pump. I had to ride my bike over 500 miles with the old pump not working.
Probably should try one sounds like a good idea 💡 guess will see great video
First Off Thank You For Your Knowledge... and also Your Honesty... I own a 2015 CVO Road Glide Ultra Twin Cooled. As for Heat I live here In Phoenix Arizona...And yes it's Hot Here sometimes over 115 Degrees. For me I don't ride if it's over 100. Even if it's 100 Degrees outside my bike Runs like a Deer with its ASS ON FIRE.... Just Ride it... Don't Complain About How Hot it is... Man UP....
Why not split the radiators? Just re-arrange the hoses. Harley does not offer oil coolers for these models, due to the cooling system taking all the forward area. Harley engineers should have considered this during the design stage. Im probably not the first to consider this practical upgrade. Ken
You did not answer my question about splitting the raditors. I presently have a 2015 Ultra Limited. Love the bike. It has 42,000 with no issues yet, except for the junk compensator, which I swapped for a sprocket. The rear wheel has rubber cushions and will take any shock load. Also went with the Hayden tensioner, execelent. A little rattle in the primary due to the clutch pack chattering in the basket. Liveable. I still think that by splitting the radiators would accomplish removing heat from the engine by cooling both the coolant and the oil. Doesn't anybody ever say "why not" or "how come"? Gotta think outside the box c'mon man.
Hi I have 21 tri cvo twin cool love it woods 22x cam
You made an excellent choice in cams! That bike has to lay down some power now!
7:00pm. I have a twin cooled CVO 2015. It had the early thermostat problem and now, at 28k miles, I'm getting the over-heating indicator again. Thermostat?
tengo una ultra limited 2019 114, 32.000 km., falló la bomba de agua.-...., la cambié y al cabo de 5.000 km ha vuelto a fallar.... (en menos de 7 días)..... no sé porque puede suceder....
I ride a 2021 Ultra and my complaint is when it's hot out 90 degrees or more the airflow from the radiator flows right onto the calf of my leg. The right side being the worst. It gets to the point where it's unbearable! I've installed Design Enginering's heat shield insulators which helped a lot, but the air flow from the radiator is the worst! It would be nice if someone made an aftermarket inner shield for the lowers that re-routes the radiator heat below the bike.
2015 Ultra Limited Low, purchased new. So far do problems what so ever. Only downside is 𝗰𝗮𝗻'𝘁 do a whole bunch to the engine as far as horsepower/torque goes. 🤷🏾♂️
Fuel Moto has some solutions that work for the Twin Cooled bikes, they've got big bore kits, cams, heads, you name it for the Twin Cooled motors.
@@GixxerFoo THANKS
Own a 14 ultra limited with 30k and it’s been flawless
That's awesome, that's what I like to hear!
delete the cat and it will be much much better.
I own a 21 triglide and I like the twin cooled my complaint is no oil cooler and no temperature gauge I plan on adding a ultracool oil cooler and plan on changing gauges to Dakota Digital
Did you do the upgrades?…….I’m thinking about doing the same with my 15’ FLHTKL………I’m just not sure about the fairing modifications that seem to require cutting the left lower fairing up to fit the cooler. Was wondering if there’s a way to avoid that?……..maybe relocating the oil filter to behind the primary like with a DK customs oil relocation kit? Not sure how to and which way to jump……..
You are making me think that "twin cooled" really means THREE methods of cooling the engine are being used simultaneously.
(1) old fashion air cooling (2) oil cooling with an oil cooler located to be hit by wind (3) liquid coolant cooling that has a radiator set-up .
Am I getting you wrong? Thank you.
Lol on that track trike bagger, hilarious! 10:02
Would adding an aftermarket oil cooler on a liquid cooled 103 engine reduce the engine heat even further? Or will it only cause more problems? Thanks
