My only gripe with this build is that you had the whole motor apart, and still went with adjustable pushrods…why? You could have gotten nice strong exact length pushrods and eliminate the chance of a lock but coming loose, or the adjustable pushrods flexing under high load which is known to happen with big power motors. This build really should have gotten solid one piece pushrods
My bike had a woods 22x cam in it when I bought it. All woods cams require adjustable push rods. So I swapped out the cam for a fueling 472 just to be able to run solid pushrods. And yes I went with Fueling for the pushrods and did a full Fueling cam chest while I was at it. Also installed S&S lifter cuffs and Fueling gorilla rocker rods (with ARP studs) for good measure.
Depends if your gun a upgrade cam shafts later. If so removable still way to go. If you have your set for life camshaft. Then already turned A 143 motor. Go with solid. Any inner cam work, oil pump work, camshaft bearing, camshaft inner chains, gearing also for timing chain. Basically if your at the end of the build use solid to size. If your starting off up grading say as you add a side car. Then two side cars. Then a trailer to an already heavy bagger. Your always building for your needs. Upgrading when parts\funds are available. Just saves bolt cutting them. Then buying new ones each time I need in there.
Most of them are but they have been at it now for so long that they are tired, jaded, back stabbed by the school's bureaucracy and red tape that they just do the minimum required to stay out of trouble and still get paid.
Went thru MMI /Phoenix in late 70's. Lot of time wasted on theory. No factory endorsements then. Was just enough to get into the game, but still ended up running a 5 technician shop.
Hi 👋 former HD tech here. Few things made me wince watching this. Should have already had rags around the rods, install piston heads on the rods first THEN slip cylinder on to the piston lining it up with the studs. Way easier.
S&S made a 143 in 2018 (don't know if they still make it) but in the description they said longevity, engine noise, vibration and throttle sensitivity had all been compromised to reach the level of performance. It came with a price tag of $9700 and had a 6 month warranty.
The Milwaukee 8 platform allows you to build a pretty reliable 143CI motor. With a bore and stroke of 4.5". The T143 you are speaking of is a Twin Cam. With a bore and stroke of 4.375 and 4.625.
Question wy didn't you put the Pistons on the rods first too simple little blocks of wood would hold engine from spinning over as you seated the rains through the bottom of the jugs
I could not find a band type ring compressor (like I usually use) that goes up to 4.5". I had to settle for an tapered auto motive type, installing the pistons through the top of the cylinder.
@@empcycleworks I guess you have to work with what you got I would be worried about dropping wrist pain keeper in bottom end with just a skirt sticking out of the jug. Love your Channel it good information
Is there slop in the connecting rods from old cams, was told the cams if well used, then you put new improved oil pump, cam plate, cam tentioner system ,(hydrolic)*, talked a lad, he said replace lower piston connecting rods also, that way there not called, thus ruining the new cams.
I like adjustable pushrods in case I have to go back into the bottom end. Especially on m8s. In fact I just put a new cam in this motor. The adjustable pushrods max it an easy job.
I'm not sure but I'm just asking if you're going through all that trouble why wouldn't you gear drive the cam and eliminate slop in the cam chain ,,,gets rid of the tensioner etc,,
Ok by going the long$ way around you'll end up with 2343cc and a bunch of careful wrenching yielding 160hp with polished intake runners bigger head whatever. But gee the GSXS 1000 for only 13000usd makes 160 crank outa the box and once you get it remapped you get 160 dyno wheel hp🦧 with out internal mods on a 500 lbs sport tourer. But can't reason with Harley heads.
30k miles on my far from stock 131ci , and haven't had 1 problem since the build and I promise you, I ride it harder than my girl!!! So that's untrue so say the least. Well at least if there tuned correctly!
How do you keep 2.3L of air-cooled V-Twin engine alive in Stop and Go traffic ? Think Key West Poker Run. Things are going to get heat saturated (I don't care how good is your tune) and start to fail and the ECM to pull timing like crazy and then all you have it's an overheating, underpowered boat anchor. Twin Cooling can only do so much and as is, it does very little . . . just enough so exhaust valve seats don't drop. These big bore kits must have the life span of a AAA battery powering Batman's flood light.
I usually use a band clamp style ring compressor and install the pistons from the bottom. Unfortunately I could not find a 4.5" band clamp ring compressor. otherwise I would have assembled the top end in the bike.
@@empcycleworks thank you so much for the reply back. I appreciate it so this gives me an idea on what this build cost because I’ve been really tossing it in my mind and considering this build on my bike. Thank you.🏆👍
And to think, such a big powerful engine like this is almost certainly going to sit in some RUB's garage until he sells it in 5 months and buys the new model year CVO, to have whatever the biggest big bore kit available is installed, for it to collect dust for 5 months in the RUBs garage. Rinse and repeat. 😅
@@empcycleworks it's called volume metric efficiency with hardlys Pistons 15° apart instead of 180 hardley's volumetric efficiency is around 60 opposable Pistons are in the high 90s and then instead of Air Cold Chinese junk cuz that's their manufactured liquid cooled put you over the top of course you would lose that farting sound that Harley's have The other bonuses would be way better gas mileage in the engine would last way longer
So that's why a 1200 is equal to a 750 Have you ever took the tour of the assembly plants I've been to the one in Hanover yeah they just pulling stuff out of those oversea containers and assembling them right there before your eyes How big is that manufacturing plant like a million square feet in China or don't get me wrong you doing amazing things and what you doing is the only part of American made it is So anyway basically you have two pistons working as one instead of you know
These builds are just for people who like to work on motors for whatever reason. My 2017 107 pulls me down the road just fine all day long. It doesn't take a big huge motor to enjoy the ride other than burning more gas. Truth be told the Milwaukee 8 is just a slightly more modern version of the 1950's/1960's hot air-cooled, big primary chain, outdated 3-hole oil fill and drain, and bottom-end cams technology. The new standard is performance and the M8 type motors have run their course, HD needs to expand their Revolution Max engine program to catch up to Indian & Honda.

I wish I could afford the 143 I would definitely have this man install that in my bike
Thanks. You can make great power with a 128!
Dayum 4.500 Bore💪
Incredible! Talent working on that stuff.
Thank you
Can't wait t see the power and torque that it makes
Me too
Well done can’t wait to see dyno numbers
Hopefully I should have dyno numbers next week!
Hey did you get it dyno by any chance yet???
great video man im getting old have a hard time picking up
complete engines anymore and putting them in the frame.
Thanks for the comment. I spend my free time powerlifting just so I am ready to lift motors like this.
Nice job and you are very informative.
Thank you. I think my videos are improving slowly.
Djeez… such craftmanship! Awesome! Keep up the good work, you absolutely know what you are doin’ 👏👏👍👍👍🤘
that thing has got to be a monster
Yes it made 171hp and 158 ft lbs of torque. I have it back in the shop to try a different cam, hoping for more power.
My only gripe with this build is that you had the whole motor apart, and still went with adjustable pushrods…why? You could have gotten nice strong exact length pushrods and eliminate the chance of a lock but coming loose, or the adjustable pushrods flexing under high load which is known to happen with big power motors.

So he can test and change cams at will?
My bike had a woods 22x cam in it when I bought it. All woods cams require adjustable push rods. So I swapped out the cam for a fueling 472 just to be able to run solid pushrods. And yes I went with Fueling for the pushrods and did a full Fueling cam chest while I was at it. Also installed S&S lifter cuffs and Fueling gorilla rocker rods (with ARP studs) for good measure.

Thank you for the compliment!
Awesome job can't wait to see how much horsepower she puts out more importantly torque
Still breaking it in. Should be next week in the dyno numbers!
Why are you more interested in the torque that it produces?
@@vernlochtefeld1626 torque is what you feel coming out of them redlights
@@vernlochtefeld1626 because it probably "motivates" a +900lbs motorcycle. You need torque to get it moving, NOW.
I've heard these bad boys can get 186hp 170 tq to the wheel.
Very detailed explanation. Good job. Thank you
Thanks you for commenting! I’m glad you enjoyed.
I wish most of my MMI Phoenix instructors were as informative as you, excellent video.

Thanks for the comment. I went to MMI in Orlando. It’s a great place to get started in this industry.

What a great video…. You made it look easy🥴 well done… now I want to watch more of yr videos 🤪
Thank you. Hopefully I can get my shop back so I can resume producing videos.
It's alive, alive ,!! 👍😎🇵🇭🇺🇲
Did you even clock the ring gaps up in the positions they’re supposed to be in?
I don’t think I did
Hi 👋 former HD tech here. Few things made me wince watching this. Should have already had rags around the rods, install piston heads on the rods first THEN slip cylinder on to the piston lining it up with the studs. Way easier.
I could not find a band clamp ring compressor for the 4.5” bore. So I had to install the pistons into the cylinder first with a solid ring compressor.
Ah yeah that makes sense 😂
Holy crap! How much power would this engine put out?
unfortunately never enough i went back to s&s and a turbo identical to the rb racing road toad
S&S made a 143 in 2018 (don't know if they still make it) but in the description they said longevity, engine noise, vibration and throttle sensitivity had all been compromised to reach the level of performance. It came with a price tag of $9700 and had a 6 month warranty.

That was a Twin Cam based motor, not a Milwaukee Eight.
I put a twin cam S&S DRAGON T143 IN MY BAGGER. LOT OF TUNING N BREAKING SHIT BUT NOW WHAT A BLAST 🎉😂

I’m curious as to why install adjustable push rods instead of solid when everything was apart?
I like adjustable pushrods in case I have to go back into the bottom end. Especially on m8s. In fact I just put a new cam in this motor. The adjustable pushrods max it an easy job.
What sort of bottom-end serves these monster cans?
A Darkhorse bottom end. Blueprinted crank with carrilo rods. Bored to accept the 4.5" cylinder sleeves.
@@empcycleworks Thanks! The bottom end is the heart of any engine, not surprised you're on it.
wow, The rings would have moved when the piston was rotated. The piston should have removed and refitted once rings and ring spacing was inspected
You are correct. Thanks for the comment
they move together no big deal
whats the part number for that fueling timing gear?
Feuling part#1091
Best video!
Man, where can I get the 143 CI conversion parts? My CVO 2022 road glide is 131 now.
I got the cylinders and pistons from CycleRama.
What is the biggest motor can I put in my 2005 lowrider Dana
S&s makes a 143 crate engine
I'm not sure but I'm just asking if you're going through all that trouble why wouldn't you gear drive the cam and eliminate slop in the cam chain ,,,gets rid of the tensioner etc,,
This specific cam is not available in gear drive. Thanks for the question!
awesome video man I did a Fuel Moto 124 to my 19 Electra Glide Standard thinking of doing a Ward 130 or doing a 143/148 build on her next
Go for it! Thanks for the comment! I want to do a 139" SO BAD! The 4.375 stroke crank on your 124 would be a great starting point!
Ok by going the long$ way around you'll end up with 2343cc and a bunch of careful wrenching yielding 160hp with polished intake runners bigger head whatever.

Stock transmission?
This bike has a Baker Grudge Box. Thanks for the comment.
What a nice video
Thank you for watching
How ya plan on keeping it cool??? Most 131's blow up and constantly running hot. Bet it doesn't get over 10k miles before toast.
A good tune goes along way with keeping these big inch motors cool. Thanks for the comment.
30k miles on my far from stock 131ci , and haven't had 1 problem since the build and I promise you, I ride it harder than my girl!!! So that's untrue so say the least. Well at least if there tuned correctly!

Thanks for the comment. We will see how long it stays together.
did you bore out the case
Absolutely
I thought the 135 was the latest from HD? i didn't even know they had a 143 for the Milwaukee 8
This is a custom size engine.
@@empcycleworks Ohhhh! nice!, looks pretty sick.
I want one please
Top loading pistons seems like such a chore. Any particular reason you do it that way? Just personal preference?
I usually use a band clamp style ring compressor and install the pistons from the bottom. Unfortunately I could not find a 4.5" band clamp ring compressor. otherwise I would have assembled the top end in the bike.
@@empcycleworks yeah I didn't think of that. Fair enough.
Hey bro which is a better performance header and mufflers Reinhardt or kromewerks
I don’t know to much about the Reinhardt but I have made some big power with the KhromeWerks. (161 hp 158 torque out of a 131.)And I perfer the sound.
kromewerks all day
Thanks man and really enjoy your panhead build
And Ron why all day
Great 👍..Sir 😁
Thank you
What is the roundabout cost of a 143 build 🤔
Somewhere around 10k. Depending on options
@@empcycleworks thank you so much for the reply back. I appreciate it so this gives me an idea on what this build cost because I’ve been really tossing it in my mind and considering this build on my bike. Thank you.🏆👍
Sorry if I missed it but what cam did you use?
The cr545 from Cycle Rama
Nice job, just a bit surprised that you used "Quickie Push rods" and not Fueling "Solid Push rods"
Why?
@@empcycleworks Solid pushrods provide a "stable and constant" no flex under stress when moving your valve system.... just my thoughts. Be safe
Which company provides this?
Thanks for the comment! Cyclerama provided the cylinders, Pistons and Cam on this build
Nice build; I’m almost positive that engine is going to scorch your inner calf’s and thighs though.
With a good tone, I think he will be alright! Thanks for the comment!

Nailed it
Yeah huge Pistons too bad you can only use about 60% of it so a equals to about a 1400 CC
Curious. Please explain.
