And with my CVO 110 thinking about going with a 222 cam . What’s your thoughts? Oh, that cam is at 222 woods Real nice for torque. Another guy running these and they’re good. I am adding a lot of compression well 10 1/2 to one. I’ll let you know how it does. I think it will do pretty good not too extreme. I just curious with the water cold heads. Really have no option for an oil cooler. My bike is a cruiser heavy to up bike long distance. We like mountain Smokies. I guess it should be pretty good . I’ll let you know the numbers I like my bike do not like the new CVO’s That’s my opinion we’ll see. Thanks. Always looking for information.
Currently running 10.5-1 with CP pistons. Full S&S cam chest and oil pump. Jim's cam bearings and Timken bearing. No Harley will ever be bulletproof, but I will trying!
I ride an S&S sidewinder 110. S&S 4 3/8 crank, and 585 cams. The only time I find the bike getting really toasty is when I play whack-a-throttle and have fun in the higher rev ranges. A good tune makes an astronomical difference from comfy to chestnuts roasting on an open fire! When touring and keeping the rpm's down, heat hasn't been a problem. TUNE, TUNE, AND TUNE SOME MORE until you get it right! Great vid!
What else is done to that 96” to get those numbers? Definitely out of the range for 95% of those builds. Seeing they dyno mid 60’s stock. What doubled the output?
@@freebehindbars8654 I have spent lots of money looking for the power I wanted on a highway bike. I certainly didnt have his kind of success with a small motor
Have a Deuce, 88 bored and stroked to 107. 10.7 compression, Woods 7h cam, all new everything internally, with the newer oiling system and cam plates. EFI is larger and ported/polished. 118hp@6200rpm, 120tq.@4000rpm - 100tq at 2300rpm.
10.5 to one , don't ride in parades or toy rides and you won't have an issue. It all comes down to riding style in my opinion, figure out what Rpm you ride in and build your bike to suit , otherwise you'll be disappointed and wasting money. Cam profiles is where you need to start.
%100. I don’t care how many cooling devices you have, you have to cut the gas with Cam2 if you’re going that route. Eventually, fans and oil coolers don’t do 💩 unless you’re moving.
@@ianm432 I blame myself for engaging. Of course you found the cure us engine builders haven’t been able to find for generations on an air cooled v twin, brilliant! 🤦
08 UG 103'' pro kit stage 3 forged 10.5:1, 259 cam, SE valve springs and clutch plates puts a smile on my face every time i twist the throttle, heat is barely an issue. 5 years with this kit and no problems.
@@GixxerFoo My 103 with 10.2 Andrews 57h cam & zippers stage 1.8 heads runs 108 hp & 115 TQ but it runs over 230 on the PV ET read out. I tried tank lift , & took out thermostat on oil cooler, vented dipstick. I put on a lanele fan & it works best when sitting at a light. My Q is will a fueling hp plate & race series pump lower engine temp as they claim ? I bought it but didn’t install yet also ordered v-thunder tc 3103 cams for more duration.Didn’t come yet. Thanks
My 2011 dyna street bob has the 110 tire shredder on it running 10.2:1 compression and a 259 cam. It does get a bit hot in traffic on typical summer days but it seems to handle it just fine. Dynoed at 106hp/122tq!!!
My 1979 Electra Glide FLH King of the Highway full dresser Shovelhead was rebuilt with 10:1 forged pistons. 0.465" lift cam. Runs perfect! 🎉 Not bad for cast iron cylinders on a 1000 lb. Battleship! 😂
I’m running 11.5 on my 131 kit with a wet head. However I do have a fan forced oil cooler with a remote oil filter. I have absolutely no heat problems in fact my fans on my oil cooler are set to come on at 235 degrees and they have only come on once on an extremely hot day.
That twin cooling was oddly designed for rider comfort but the "side effect" was being able to run higher compression like that and get more performance!
@@GixxerFoocan u recommend a set of pistons or big bore kit budget friendly for a evo and few other mods other than a andrewes ev27 cam I wanna bump the compression up to 10:1 or 10:5:1 but I don't know anything about evos.

2012 road king with just complete cobra exhaust front and back with crossover and high-performance mufflers. Thunder max tuner and Dino tuned with a big snorkel Air.79hp 115 torque.its because of mufflers, I believe
My S&S 551 cam in my 103 was perfect at a stock compression of 9.6 with a 216° valve intake duration. It is now a 107 with heads and 10.0. It runs well, but it was happier 500 rpms earlier with less compression.
BIG G'day GixxerFoo from Down Under 🇦🇺 Merry Christmas 🎉🎁🎄🎁🎉 to you & the family 🖤🧡🖤 THANKYOU for another great year full of weekly videos with amazing content & great information too. May all your days be Harley days🖤🧡🖤 Safe travels 🙏♥️🐾🐾🇦🇺
Agree, my 2002 Twincam went from 88 to 103. Bigbore and stroker, (Stage IV SE) reworked heads etc. 10.5:1 ratio, with manual compression release. 259 cam, SE valve springs and clutch plates. With my LFP battery 96 Wh 420CCA, turns smooth and easy. 107hp and 162 nm torque. Never had a noticeable heat increase. An oil cooler would be preferable though.
I have a 2014 Road King with the 103ho ...it was a big upgrade for me coming from a 01 road king with the stock 88 .... i dont know what the numbers are but its just fine right now. ..
I'm more interested in corrected compression ratio. I personally aim for about 9.5 corrected compression ratio. Gives me cranking compression pressure of about 195 psi. This means I can still run 92 octane and keep the engine reliable. What this video is failing to talk about is if you are running a 10.5:1 compression ratio then you need a cam that really hangs the intake valve open longer. These aggressive cams aren't designed for low end torque where most people ride. Sure, you gain low end torque through bigger displacement but then you lose it again because the intake valve is still open while the piston is coming back up on the compression stroke. You need to have the RPMs up higher to make this efficient. A better plan is to talk to the guys at Fuel Moto or similiar. Tell them what you're trying to accomplish and they'll give you a tried and true parts list that compliment each other. If you want to figure it out on your own, Big Boyz Head Porting has some of the best calculators to help figure out what your end results will be.
Had 110 kit on my 103 10.5.1 tried and trued and tuned by well known tuner , just wasn't impressed so went with the fuel moto 107 kit 10.2.1 same cams , wood TW555 and finally have very manageable power and less heat than stock and finally a great riding experience 😎
The 114 has pretty good compression stock compared to the Twin Cam. Paired with that 4 valve head that's a lot of the reason why we see such high gains with cam swaps.
I'm running an 88@10.2:1 with Wood's TW6H cams. .590 lift/ 240° duration. It's very street friendly and pretty fun at the track too. I took a bit of time getting the jets right, but she'll run with the 110's and 114's pretty competitively.
Looking to go from 96" to a 107" with Woods 222 cam (for the grunt off the bottom/mid range). I'm thinking 9.75:1 comp without compression releases on a Softail. Or just bolt the cams in stock and see if that's enough. What say the jury?
I have a 2018 with the 131 screaming eagle kit. i live in florida. i dont really feel any difference in heat. i am getting 145Tq and 142HP. all i need lol. only thing different is mileage. i am very pleased.
Thank you for another informative video. And Merry Christmas. These new engines are so much different than the old ones. I remember back in the Shovelhead days the hot rod guys would tell you that a Harley can take all the cubic inches that you could give them. But they couldn't take allot of compression. I don't know if that's true. It's just what they would tell you.
I run a S&S evo 124” with 11.6:1 compression and a custom 2into1 pipe. It’s unbearable at a standstill in the summer. No parades or high traffic areas for me.
Has anyone ran the derale 2-pass heatsink cooler 13279? Considering running one of these vertical on the down tube with a Jagg viscosity regulated filter adapter. Going to 107", 10.5:1 carillo pistons, 777 cams, ported heads and throttle body.
Me Mate at the Local bike shop told me that Dyna rubber engine mounts do Not Like big bore Kits....... Good Luck ! ( and Merry Christmas y'all ) from West Aussie
@GixxerFoo I see a lot of talk about cams and big bore kits, but you don't see much about head work. Coming from the car world, good flowing heads are key to making power. Why is there little to no mention of this with Harleys? It's always cams, then bore, and maybe then "Oh yeah, get some port work done." Just wondering... Merry Christmas!
Harleys make really good power with cams and big bore kits with the stock heads. Port work or buying performance heads can be anywhere from 500 to 3K bucks. It comes down to extra cost, extra down time, finding someone to do the work or shipping your heads to a shop on the net and hoping it all get's done right and they come back in one piece from the shipping my company. That's just my guess on the matter.
I'm going to upgrade my '95 Evo Electra Glide to the KB pistons and bump the compression from 8.5:1 to about 9.6:1 and go with a Comp VThunder Extreme Energy cam with 236 duration and .569" lift on the lobes. That should make this old touring bike into a mountain climber with torque to spare. I run 90 octane ethanol free gas and my bike runs great on it.
The mighty VTwin is a nice engine. Been running several models for decades. I think almost everyone knows they are made for old white guys. If I was looking at a more powerful engine/bike, I would be looking more toward the metrics. Many of them can go faster in 3rd gear than my most powerful VTwin can in overdrive. Just my personal thoughts. Like your vids Gixxerfoo, Keep em comming.
Great video as always man. Question….which oil cooler would you recommend for my 2015 fltruse wet head with the 110-117 SE kit? South Carolina summers get pretty hot or do I even need one? Thanks and Merry Christmas Gix!
Hey Gixxer! Happy holidays to you and your family, been subscribed to your channel for a while now, love your content. I’d love to pick your brain on the best way to amp up my 08 Dyna low rider 96cubic inch. In a way that’s pretty affordable and would keep the bike reliable. I would have to pay for labor, as I don’t have a garage at the moment. But I’m looking to get around 100 horsepower and about 110-120 ft pounds of TQ. For about 3-4k if that’s possible, (with labor) would Love to hear your insight. Have a great new year! Forgot to mention my bike has a stage 1, exhaust and air filter. Exhaust is Vance and Hines 2 into 2 big bore radius
Sorry for the late late reply, but I appreciate your support on the channel! It's gonna be a challenge to hit the numbers your looking for with parts and labor but to keep you on budget at least I would look at a cam set swap. The labor is what's gonna eat theb budget more than anything. To get the most bang for you buck on a cam swap the TW-222 would be a great way to go. Since you've got the exhaust and air cleaner that should get your 96 around mid 90's on the horsepower and right around 100 ft lbs of torque. Getting a good dyno tune, parts, and labor all together that should keep you on budget and get you really close to your numbers. You won't be disappointed at all with a cam swap!
ruclips.net/video/iM-rgPXBoj4/видео.html, here's a video where I covered the benefits of compression and some of your options for adding compression releases to your bike if it's not already equipped with them. You don't have to go to a machine shop to add a compression release to any bike!
Curious, I’m bumping my 110 CVO sir compression up to 10 1/2 to one. So it is a 2014 CVO so it has the water cold heads. Your thoughts. I don’t think I can put an oil on that bike. It has a water pump.
I have the S&s easy start cams and noticed sometimes it’s hard to turn over. I’m thinking of adding g a high torque starter with a lil larger battery. What ya think?
Speaking of compression, the screaming eagle 107-119 kit comes with 11 to 1 pistons. Even with 93 octane pump gas, the heat coming off that must be almost unbearable. I would have to install oil cooler.
You didn’t mention Sportster big bore kits Hammer says the 1275 kits don’t have a problem with more heat, but every video I’ve watched on RUclips reviewing the 1275 says they can feel a lot more heat coming from the engine after I’m very concerned about putting the kit on my 2000 XLH883
There's not heat issue on those, the hammer kits are the best out there. They shed a lot of heat and cool really well is what most people are referring to in my experience.
Alright, I need advise fellas! 98 Fat Boy FLSTF, what should I go with? Looking for streetability and reliability with performance! A happy medium, size and brand suggestions? Let me know guy's, oh already got an oil cooler installed! Thanks
I had a question, maybe some people could help me out. I'm thinking about doing a 97 cubic inthat's a cute weekend 10 and a 1/2 to 1. Jim's big board kid comes with cylinder's heads, rocker box pistons and piston rings. With delkron cases I'm more or less looking for suggestion on Parts to keep reliable
The cases are for sure gonna up the reliability big time! 10.5:1 will make it scream, just add a good cam, cam plate and high volume oil pump. Make sure you change all your bearings for sure, get a good tune and you'll be good to go.
My dude, I have a 2005 dyna, I was looking to get a big bore 100 sns kit, cams, full exhaust, etcetera, maybe even heads. I've seen lots of good commentary on the 100 kit but I've also seen some detractors, particularly a guy that blew his motor, stating that the cylinder head and the sidewall is two different types of metal and are prone to such problems. Is this true? Is this true of Harley cylinders as well? Like stock? Really want to get more power out of my bike but also care about longevity, thanks dude
The pistons and the cylinders have a anti friction coating from the factory in my understanding. I haven't seen any major failures on big bore kits due to dissimilar metal. The biggest cause of failure on big bore upgrades is usually improper tuning being the main culprit. Then improper break in, workmanship and lastly manufacturing quality happens but rare.
@@GixxerFoo thank you so much for the reply bro! Turns out after seeing my mechanic, he recommend I don't go with the bore kit considering the age on my engine, however we are going to do a host of other things, cams, heads, all new suspension, exhaust intake etc, everything should be done by the end of this month, really hyped for it
From what they are saying is it's 10.7 with 1mm oversized valves in fully machined cnc heads. I don't really buy that honestly but they are spinning those motors to 7,000 rpm. That's a lot for a big twin.
Sounds like this video is based on twin cams. Most fuel motos big bore kits are way over the compression ratio you're saying is safe. Your videos are amazing but just wish they were more based on M8s
The cam has a lot to do with what is a safe compression ratio. When the valves open and how long they stay open changes cylinder pressure. You may have heard the term dynamic compression. Talking to an experienced builder about your goals and how you ride is a good place to start a build.
Depending on the application of the build. For distance riders I prefer to stay on the conservative side ,I have gotten into the wilds and found one grade of gasoline at the pump which led to pinging rattling and predet. Bar hoppers I like to go all out. There is No subistute for cubic inches or pubic inches LOL Merry Christmas Gixxer, Another great video.
What compression ratio do you like to run on the street? Do you go big, keep it stock or split the difference in the middle?
Running 10:5:1 CP carillo pistons Fueling 594 cams Screamin eagle MVA heads Twin cam 110 only made 105 horsepower and 116 Torque.

That should make this old touring bike into a mountain climber with torque to spare. I run 90 octane ethanol free gas and my bike runs great on it.
Good information...
The mighty VTwin is a nice engine. Been running several models for decades. I think almost everyone knows they are made for old white guys. If I was looking at a more powerful engine/bike, I would be looking more toward the metrics. Many of them can go faster in 3rd gear than my most powerful VTwin can in overdrive. Just my personal thoughts. Like your vids Gixxerfoo, Keep em comming.
Great video as always man. Question….which oil cooler would you recommend for my 2015 fltruse wet head with the 110-117 SE kit? South Carolina summers get pretty hot or do I even need one?
Thanks and Merry Christmas Gix!
I like tobstay with stock compression.
My bike also has oil cooler on it factory. It doesn’t really run hot for 103.
Hey Gixxer! Happy holidays to you and your family, been subscribed to your channel for a while now, love your content. I’d love to pick your brain on the best way to amp up my 08 Dyna low rider 96cubic inch. In a way that’s pretty affordable and would keep the bike reliable. I would have to pay for labor, as I don’t have a garage at the moment. But I’m looking to get around 100 horsepower and about 110-120 ft pounds of TQ. For about 3-4k if that’s possible, (with labor) would Love to hear your insight. Have a great new year! Forgot to mention my bike has a stage 1, exhaust and air filter. Exhaust is Vance and Hines 2 into 2 big bore radius
Sorry for the late late reply, but I appreciate your support on the channel! It's gonna be a challenge to hit the numbers your looking for with parts and labor but to keep you on budget at least I would look at a cam set swap. The labor is what's gonna eat theb budget more than anything. To get the most bang for you buck on a cam swap the TW-222 would be a great way to go. Since you've got the exhaust and air cleaner that should get your 96 around mid 90's on the horsepower and right around 100 ft lbs of torque. Getting a good dyno tune, parts, and labor all together that should keep you on budget and get you really close to your numbers. You won't be disappointed at all with a cam swap!
Could you maybe try doing a video on compassion releases?
ruclips.net/video/iM-rgPXBoj4/видео.html, here's a video where I covered the benefits of compression and some of your options for adding compression releases to your bike if it's not already equipped with them. You don't have to go to a machine shop to add a compression release to any bike!
Merry Christmas. God bless you and your family 🎄🙏
Happy holidays!
Curious, I’m bumping my 110 CVO sir compression up to 10 1/2 to one. So it is a 2014 CVO so it has the water cold heads. Your thoughts. I don’t think I can put an oil on that bike. It has a water pump.
You sound so much like project farm!
I have the S&s easy start cams and noticed sometimes it’s hard to turn over. I’m thinking of adding g a high torque starter with a lil larger battery. What ya think?
Speaking of compression, the screaming eagle 107-119 kit comes with 11 to 1 pistons. Even with 93 octane pump gas, the heat coming off that must be almost unbearable. I would have to install oil cooler.
You didn’t mention Sportster big bore kits
Hammer says the 1275 kits don’t have a problem with more heat, but every video I’ve watched on RUclips reviewing the 1275 says they can feel a lot more heat coming from the engine after
I’m very concerned about putting the kit on my 2000 XLH883
There's not heat issue on those, the hammer kits are the best out there. They shed a lot of heat and cool really well is what most people are referring to in my experience.
If you take your motorcycle on vacation, it's nice to have it set up to run on 87 Octane gas.
Alright, I need advise fellas! 98 Fat Boy FLSTF, what should I go with? Looking for streetability and reliability with performance! A happy medium, size and brand suggestions? Let me know guy's, oh already got an oil cooler installed! Thanks
Again great info.
Thanks again! Thank you for your support this year!
“While that’s true to a degree” I see what you did there
I had a question, maybe some people could help me out. I'm thinking about doing a 97 cubic inthat's a cute weekend 10 and a 1/2 to 1. Jim's big board kid comes with cylinder's heads, rocker box pistons and piston rings.
With delkron cases I'm more or less looking for suggestion on Parts to keep reliable
The cases are for sure gonna up the reliability big time! 10.5:1 will make it scream, just add a good cam, cam plate and high volume oil pump. Make sure you change all your bearings for sure, get a good tune and you'll be good to go.
@@GixxerFoo It'll have ASN S585 cand I wanted to go with a velocity stock.
You don't also have a small radiator.
By d k custom
My Zippers 107 Muscle kit is 10 5 1 with 577 cams I use a oil kooler and Love Jugs
What oil cooler are you suggesting? Is this a stock oil cooler?
Honestly any oil cooler will do unless you want to get into an aftermarket with more rows than stock, but stock does pretty dang good as it is.
🛑🛑 Merry Christmas, Gix !!🎄🎁
Merry Christmas to you too!!
Gix what do you think of S&S Easy Start cams ?
I love that concept and they work very very well. Biggest thing is if the cam in the easy start version is what you're looking for in a cam.
My dude, I have a 2005 dyna, I was looking to get a big bore 100 sns kit, cams, full exhaust, etcetera, maybe even heads. I've seen lots of good commentary on the 100 kit but I've also seen some detractors, particularly a guy that blew his motor, stating that the cylinder head and the sidewall is two different types of metal and are prone to such problems. Is this true? Is this true of Harley cylinders as well? Like stock? Really want to get more power out of my bike but also care about longevity, thanks dude
The pistons and the cylinders have a anti friction coating from the factory in my understanding. I haven't seen any major failures on big bore kits due to dissimilar metal. The biggest cause of failure on big bore upgrades is usually improper tuning being the main culprit. Then improper break in, workmanship and lastly manufacturing quality happens but rare.
@@GixxerFoo thank you so much for the reply bro! Turns out after seeing my mechanic, he recommend I don't go with the bore kit considering the age on my engine, however we are going to do a host of other things, cams, heads, all new suspension, exhaust intake etc, everything should be done by the end of this month, really hyped for it
Amsoil V twin 20-50 took half the heat away. Big time cooler.
I saw alot engines blew up in the bagger series races. What compression do the teams run?
Alot
From what they are saying is it's 10.7 with 1mm oversized valves in fully machined cnc heads. I don't really buy that honestly but they are spinning those motors to 7,000 rpm. That's a lot for a big twin.
Sounds like this video is based on twin cams. Most fuel motos big bore kits are way over the compression ratio you're saying is safe. Your videos are amazing but just wish they were more based on M8s
With the right tuning and a big oil cooler, maybe even fans you can run some really high compression on the street with a Twin Cam or even an EVO.
@GixxerFoo I hear ya, but FuelMoto sell BBK with 12:1 compression. Will you be doing more M8 videos in the future?
The cam has a lot to do with what is a safe compression ratio. When the valves open and how long they stay open changes cylinder pressure. You may have heard the term dynamic compression.
Talking to an experienced builder about your goals and how you ride is a good place to start a build.
Depending on the application of the build. For distance riders I prefer to stay on the conservative side ,I have gotten into the wilds and found one grade of gasoline at the pump which led to pinging rattling and predet. Bar hoppers I like to go all out. There is No subistute for cubic inches or pubic inches LOL Merry Christmas Gixxer, Another great video.
Merry Christmas to you too! Thank you for the support this year!
10:01. Better safe than sorry.
Stocker
Bored my 88 to 95 with kb 10:1
What about m8 107 with big bore kit?
M8 you can get up there as they are designed to handle a bit more heat.
I went FM 124”. Runs cooler than the stock tuned 107 with the cat.
@GixxerFoo I'd like to install a s&s 129 is that possible with the short stroke of the 107.
@@GixxerFoo can the 107 handle the s&s 129 big bore kit withe shorter stroke
At this point in my life it's not about higher horsepower and speed, it's more about comfort and reliability.
just need adequate power ,not stupid power
ICE. More Power = More Heat. Always have and always will.
The cool fuel cans are pretty cool!
