143ci Lowrider S / APE / D&D Lowcat

- This 143ci got a slightly different combination than the last one I built.
The CR515 Cam from A.P.E proved to be a great choice that provides massive torque that is delivered smooth for street riding.
With stock valves, the HP is a respectable 156Hp which makes for plenty of fun at the twist of the throttle.
I have explained this time & time again but once more for the new viewers. I am located 2200ft above sea level & my dyno readings are therefore 6% lower than they would be at sea level. It is a known fact that you loose about 3% of power per 1000ft of elevation. Me sitting 2200ft above sea is ultimately holding my numbers back at least 6% so the numbers would be sitting around 165Hp & 183ft/lbs.
The crankshaft is an OEM one that has been trued up, plugged & welded with oversized big end bearings.
The compression ratio of this particular build is 11.7:1 (static)
Heads are Stage 2 from Alpha Performance Engines & feature stock valve sizes with hand porting & texturing. The valve springs have been replaced to accommodate the higher lift cam.

Just like a skilled surgeon. Where most of us would struggle, Mr. Miller makes it look easy. Fascinating.
Thanks for watching
I'll never get tired of watching where you are going with these builds mate. They are a very rideable bike as long as you don't get on em too fast out of the turns🤣
Thanks for watching mate. Catch up soon
Thanks again Tommy,super easy to ride in traffic, when you open it up every thing goes by in a flash
Glad you like it mate!
Wicked Low Rider S. So's Mr. Miller's masterpiece of an engine. To me, the ultimate ride.
Love the videos! awesome content.
Awesome 👌 very nice build.
Great video & content Tom
Nice! Looks sounds and ride’s amazingly powerful
Very tidy workmanship awesome
Outstanding!
Love your work 😊
Thanks for watching
That has to be the best looking LR S I’ve seen. Killer with that engine.
Thanks for watching 👍
Totally agree.
I love seeing your builds Master Tech Miller. Another one in the books.
Thanks for watching
sounds like a beast!!!
Torque monster! Keep up the good work Tommy 🤙🏽
Cheers mate! Appreciate the support across the channel
Appreciate your hard work in these videos sir! Keep up the good work.
Thanks for watching
Mr milller what program are you yousing to tune. Also what do you think of a 22XE cam in a 114 street glide. Would you recommend something better makes more power and torque and sounds very nasty in idle
@iginogasparini3369 I mainly use & reccomend Technoresearch Direct Link for all my tuning.
I would suggest the CR480MT for your application
That is an outstanding all around performer on the perfect HD chassis.Lowrider S is very versatile. Mine is a '22 Black,no regrets. 👏👏👏💀
Awsome informative vid nice work
Thanks for watching
Monster 🤙🏽🤘🏽
STD:STD is Another power correction standard determined by the SAE. Power is corrected to reference conditions of 29.92 InHg (103.3 kPa) of dry air and 60 F (15.5°C). Because the reference conditions include higher pressure and cooler air than the SAE standard, these corrected power numbers will always be about 4 % higher than the SAE power numbers. Friction torque is handled in the same way as in the SAE standard. The dyno corrects for air pressure or density altitude already.
That's awesome!!!
Hello...Nice build with an interesting cam choice (CR-515); awesome numbers (173+ torque & 156+ hp) and excellent curves, specially the torque. This combo would be great on a Bagger (touring chassis) such as my Road Glide ST, which I've set up with upgraded suspension (and more) for 2-up riding along the coast here (So. Cal.) and up in the hills/mountains inland, with all the curves & twisties. Well done!
My current Project: '23 Breakout, S&S 132 top end kit, Darkhorse blueprinted/upgraded bottom end, S&S 550 cam w/full S&S cam chest kit and top end kit (roller rocker arms, etc.) and reworked/upgraded Heads (oversize valves, port work, etc., etc.]. Might look into some cams from Star Racing...3/4 Race (585 lift) and full race (615 lift, power band 3000-7000 rpm). The full race might be a bit too much for a street bike, and even the 3/4 race cam (from what I hear) is definitely for above average aggressive riders.
Keep me posted on the build process. I'd love to know how it comes together.
Thanks for watching!
I just finished the build on the 132 , used the 515 cycle Rama with springs , 55 mm manafoild , 5.5 injectors , Trashin exhaust , Mash air cleaner . 151 torques 128 hp . The bike is fast and the cam works better than my 128 with the 475 with S&S , Krome Works 2 isn’t 1 . Might change to a 515 at some point on the 128
Wow!! That’s bloody amazing, very quick, wouldn’t mind getting my ST done
Thanks for watching! Are you in Australia?
Yeaha mate I live in BeerWah, Sunshine Coast.
@cliffmarriott4244 yeah cool. Well I'm only about 2hrs away mate & would love to put together something for you.
You can email me at workshop@ddhd.com.au if you would like any further information
If I had a guy like you near me I would buy a Harley tomorrow....
Amazing! There goes the rear tyre 😂
🤣😂🤣
Great video , was surprised not to see updated cam plate and no roller rockers.
Upgraded cam plates are now considered to be cam chest jewellery.
Roller rockers are not showing any benefits at this lift (.515")
They should be considered when using over .600"
Keep up the great work my friend , cheers from northeast Pennsylvania
I like how you add some pov footage at the end.
Thanks for watching!
Nice,
Now that's a bike.
I really love this build tommy. Looking for a build on my LRS... trying to decide between a 128ci high comp or something like this.
Thanks for watching!
Are you in Australia?
@@MasterTechMiller certainly am!!
@@alexking1251 email me at workshop@ddhd.com.au if you'd like to get the ball rolling
I want the 131 on my low rider s 👌
Great build Mr Miller, do you believe in running in a new or rebuilt engine or do your rev them from the get-go
Great question.
So I set all the clearances & ring end gaps during assembly. I heat cycle the engines with no load (just idle speeds & a few free revs here & there).
After that it's straight to the Dyno to set the Air/Fuel Ratios ASAP to ensure no washing of the bores or and lean conditions are happening.
So in, short, NO, I don't believe in running in engines.
Smashing it Tommy, but nooooo that air filter ! cost about 10 hp methinks?
5 to 8 Hp for sure
This should be good for a 9 second run (the time it takes to lose my licence!).
🤣😂🤣
Really nice street friendly looking build. What heads are there? Clutch is looking stock, springs upgrade only?
Thanks for watching.
All details are listing in the video description
This was a great build, what would be your second choice of exhaust?
Bassani would be my 2nd choice for 2-1 systems.
If you're after the 2-2 look then go with the FREEDOM pipes.
Those stock rods on that ? I’d think theyd do the h beam rods along with that welded and true crank.
Bro I’m loving your channel.
Watch this in the morning then go to my shit job planning out rail freight. Ugh. If I could do it all over I’d be building bikes and makin power. Here I am 41 and Harley’s are my life. Where I grew up it was a good college or disowned .. the fuck ups went to UTI to learn to work on cars and bikes.. oh boy they laughing now lol.
The OEM rods are good for upto around 200hp.
If you are doing a boosted combo then I'd definitely be running some bigger, stronger rods.
So much for everyone saying you can't make power with the "restrictive" stock air cleaner. Lol. Those are some strong #'s.
No assembly lube on that cam lobes and chain? I diddnt even see you go in the lifter bore with any -oil in the hole only…
Your explanation was subpar about priming it
Ever think you might not get those noises had you used assembly lube?
wait a minute... are you telling me you slapped the bike back together with the stock clutch and transmission?
So is this the 131 engine being worked on for a new bore or is it off the shelf this?
This is a custom build. Cylinders are taken from 107 / 114 / 117 engines. The OEM liners are bored out & we have very heavy duty thick wall 4.5" liners installed. The engine cases need to be bored out to accommodate the larger cylinders. We put welded cranks in these too.
my Harley shop recommends using 2 into 1 super trapp ,have you ever tried one
Not on a big inch build. Have used them on 114ci bikes before with decent results
Crikey, that's enough torque to sheer the threads off the nuts that hold the Sydney Harbour Bridge together! Why do Australia post insist on using Honda step throughs? A centrifugal clutch and an all up shift pattern, and a bike like this would be ideal for them. Great for dairy farmers, too. Less time herding up cows and taking them to the dairy twice a day and more time to plough paddocks... if rounding the cows up on a bike like this didn't achieve both goals at the one time.
It's really nice. But from a practical standpoint, where you gonna use all that power without killing yourself?
To get a Latte coffee quicker than the boys
Is there a way we can get a base map for a 128 with that cam?
Email me at workshop@ddhd.com.au
Please advise/ remind me about the oil flow issues…which model years need some type of work around? Thanks.
Are you talking about oil pumps?
@@MasterTechMiller Wasn’t there some kind of issue with oil bleeding some where or not flowing with the softails or sumping whatever that means? I am vague on the terminology. If so what years were affected if buying a used Softail?
@dry509 There is no issues with Softails sumping or any oil flow/bleed issue.
The Early Touring models (2017-2019) had a sumping issues which has since been rectified with the new oil pump which was fitted in all late 2019 models & on.
If you have a 2017 to early 2019 you can replace the oil pump in them & there is no problem

@@MasterTechMiller Great. Thanks.
how much did this build cost?
What does a 143 kit like this cost. Keen for something like this once mine needs a rebuild.
Starting around 15k ride in ride out
@@MasterTechMiller awesome thanks
What did you youse for a tuner to tune it

can one of these or something like it be done to my Yamaha Stryker? I was thinking S&S 120
No

I’m building a 132 for my lower rider st 2023 , I have a 475 in it now with 55 injectors and 55 S&s polished manifold , thrashin two into one . What cycle rama cam would you recommend .
What compression ratio are you chasing?
@@MasterTechMillerit is the S&S 132 maybe 11+
I was going to use S&S 540
I’m getting on the dyno now 138 torque 118 HP Mash air clearer
@@charlesmccurry3602 I wouldn't use the S&S 540
I know of a few guys who have tried it & been left underwhelmed & changing it out.
I would go with the CR515 from Alpha Performance Engines
and what about engine resource , is it lasts longer or less ?
This is a high performance engine & of course it will require more maintenance than any factory engine.
If more maintenance & the fact this engine will require tear down, inspection & possible replacement parts is something that bothers you then it's not the engine package for you.
I suggest 4000km service intervals with this big bore builds.
@@MasterTechMiller anyway u doing amazing job gl 🙌
I just posted my finished my 132 build posted it on reply

a drag race with a stock model would show the real dif.
This would do an easy 10.1sec at around 127mph. I've never ran (or seen) at stock 114ci do the 1/4 mile but my experience says it would run around 12sec at 105mph
@@MasterTechMiller thanks for the info. it would be great to see it for real. Also a drag race between a 143ci and a sportsbike... A bit what carwow is doing
Tf is a 143 and where do I get it
If your in the States, hit up Cycle-Rama in Florida. If your in Australia hit us up at www.alphaperformanceengines.com.au
@@MasterTechMiller thanks
Price?
143ci kits start at 15k ride in ride out fully built & tuned
You better hope those stock clutch and primary parts can handle all that power i sure wouldn't do it your compinstator will explode
Comp ramp has been upgraded to a billet steel ramp that has been heat treated & induction hardened.
We have proved time & time & time again that when the OEM clutch springs are upgraded to the 1275nm springs from SE that the OEM clutch can handle more than people give it credit.
I personally ride & race & drag race on the OEM clutch with upgraded springs. Just like George Bryce from Star Racing.
Don't be a sucker & think you need all these peices of jewellery for your engine.
All that $ on a monster engine and still running a stock air cleaner?
