- Starting with a trued & welded crankshaft, this build is designed for the customers individual needs & wants out of the bike. Wanting to do more track days & adding a little more grunt down low through to the mid range.
The Crankshaft used starts life a stock Harley-Davidson unit, before it is trued up to under 2thou of run out, an oversized big end bearing is installed & a crank 'Plug' is used over the factory Pin. Finally it is welded into place to prevent movement under harsh conditions.
I remove the S&S 475 Camshaft previously installed by me when the original build took place & I install the A.P.E CR483 Cam. New cylinders & pistons were installed for good measure to give the engine a new lease on life.
I also added the Fueling OE+ Camplate to ensure enough oil would be passing through it the critical components of the engine under high rpm demands on the track. A Fueling Cam chain tensioner was thrown in to complete the cam chest.
For the intake manifold, a Screamin' Eagle 55mm unit was fitted with A.P.E 6.2gps injectors.
Screamin' Eagle High Capacity lifters were installed & the Screamin' Eagle adjustable pushrods were re-used to complete the build.
If you have any other questions please leave them in the comments. I read all the comments & try to get back to them as soon as I can.
Please remember guys, I try to keep the video's as entertaining & flowing as possible so if you don't see a certain procedure done or you think I haven't done something it's most likely because I have left it out of the final video on purpose to keep it flowing.
All engines I build are heat cycled numerous times before dyno tunes & carried out. You may notice that between me building the engine & tuning it, I have actually got a hair cut which would indicate some amount of time has passed between scenes.
Final numbers produced on the dyno were 125hp &147ft/lbs

Thanks again for watching & supporting the channel! MTM
Absolutely love your videos Tommy, always well explained and entertaining. Makes me want to take my Lowrider S up to QLD and pay you a visit for some more cubes 🤙
Cheers mate! I appreciate the positive feedback and support!
I'd love to put something together for you mate
Road king special is where its at!!!!!!!!
Another master class Tommy. Thanks for sharing your knowledge about what specs go into your engine build’s.
Cheers mate! Glad you enjoyed it👌🏻🇦🇺
It certainly is a joy to ride, thanks again Miller for all your efforts.
Man that thing shot off as soon as you squeezed open the throttle. Well done mate, fantastic build.
Thanks mate! Yeah it definitely gets up and goes!!! Peak HP numbers are not what's important when your after instant throttle response and massive pulling power 💪🏻
What a rocket. I’d love to see it on the track
He definitely knows how to crank it over in the turns
Gotta test it out and break it in.
I’d have zero issues having a builder and tuner I know and trust letting her rip even if I wasn’t a close friend
You can ride my bike like that anytime ya want brother. That thing is quick af.
She definitely gets up boogies!!! Probably not as much as your 131ci Lowrider S but still no slouch
I see you used the new cyclerama 515 cam but I was thinking of going with the 485 cam in a stage 3 122 with the first generation cnc heads, upgraded injectors, etc.. So do you think I should stick with the 485 cam or would the 515 be better
The 515 will work just fine in the 122kit as the compression ratio is 11.0:1
The 515 is basically the exact same cam as the 485 but with more lift. The higher lift requires bigger calave springs to accommodate the lift.
Good stuff addressing the bottom end..many only concentrate on the top
Bloody awesome 👌
Thanks for watching
WOW absolutely awesome, great build Tommy , love the giddy up & go
Plenty of mumbo that's for sure
hey tommy long time no talk nice build doing these cranks is key

Cheers mate 👌🏻🇦🇺
Simply awesome.
Great video, Looked forward the next one!! keep up the qaulity
Thanks mate!!! I've got plenty of content on the way 👊🏻
Trying to mix it up a bit and show/talk more about different things each video.
Love these vlogs so much knowledge and sharing it plus not scared to thrash them shit did that thing take hits 200kph so fast
Cheers mate! Glad you enjoyed it
💪🏻
Good stuff Tommy. Hope I can build something nasty like that. $$$$$ limiting me ... one powerball
That hooks up well 👌
Awesome engine builds Tommy
Thanks mate 👌🏻
Be good to find a bloke like you in NZ
Dammm that thing took off....
From 100 up Boooom
Definitely no slouch!
Fantastic
If you were my mechanic you automatically have the right to ride it however you see fit!!! 😂
Quite frankly, I want my bike to be road tested proper. Shaking it out is the final step before I want to pick it up.
Great power 👌 good job.
Thanks mate 👊🏻
Cycle rama 483 is it....hope we can get them here in the states
You can get through Cycle-Rama
@@MasterTechMiller ....good to know, thank you.
man..I like your channel content.. that micrometer will distort on the vice when you tighten that to clamp...
Cheers for the support on the channel maybe.
In regards to the micrometer. No it won't. It's literally just sitting in there with soft jaws so it's steady. It will distort more if it hold it in my hand as my body temp will transfer through it.
They make micrometer clamps that do the exact same thing.
Fast , brakes and suspension upgrade should be next then .
Since filming, it now has Ohlins cartridges in the front with 3inch over tubes, 14inch remote res legend rears with 1inch extension for a total of 15inch, swingarm has been modified to allow for transmission pan clearance.
Galfer rotors are next. Currently runs upgraded pads on stock rotors
Super rad. Risky filming yourself riding at those speeds in the road?
When (if at all) would you install "top end guardian kit", please?
When you have excess money that you can afford to waste on it
another fabulous build!!!! who's cylinders and pistons do you use?
Alpha Performance Engines.

Hi Tommy, what's your take on crankcase/cyl head venting? It's not something i've heard you talk about. thx.
@@ihateemael Are you talking about venting the trans cover & blocking the ports in the head?
@@MasterTechMiller I read somewhere the breathing system has changed in the latest models. What do you think is the best setup to use for our older m8s?
@@MasterTechMiller Tommy my 107 Fatboy has had poor performance since I got it. I took your advice and fitted an aftermarket air cleaner assy and it made quite a difference, thx.
But today I just fitted a catch can and it's a different bike. The engine is now free revving, and zooms up my local mountain pulling a gear higher.
cheers from a happy Richard.
Hey Tommy, is it possible to purchase a bike from the dealership and have you throw a kit on it.. I really enjoy your videos thus why I subscribed..
Glenn
Absolutely 💯 We have done this before for guys interstate. They have purchased the bike through out Dealership, I've done all the work on the bike & engine from new, carried out all the dyno work etc and then we've shipped the bike to the customer hassle free.
You may wish to chose to come and collect the bike from us and ride it home.
Shoot me an email at workshop@ddhd.com.au if you would like any further information on how we can make this happen.
Sick build Tommy does the owner video from the track days?
Yeah mate 👌
@@MasterTechMiller do you have a link? I'd love to do a track day on my SGS. Did he do lakeside, QR or Morgan Park? King of the baggers kind of shit 😈
Yeah that's how I ride too haha
Thanks for sharing. I noticed you still used adjustable pushrods even though you had the top off. any reason you didn't reuse the originals?
The initial build when the bike was sold was just a stage 2 kit with the S&S 475. The stock pushrods were cut out and adjustable ones were used then.
Then the 128 bolt on kit went in later on and re-used the S&S 475 Cam.
This time around I just re-used them again because the customer had already paid for them.
Fun fact: this would not pull out a decent stump
🤣😂
