- It finally arrived!!! I'm more than excited to have this bike built for the drags at Benaraby. You will get to see how brand new Harley's come in the box delivered to the dealers. Watch along as I tear it down & build it back up to a 128ci. This build is using the A.P.E 128ci kit along with their 'Performer Heads'. I decided to run with the D&D Fat Cat 2 into 1 pipe because not only does it look & great, but it performs great with this setup! The CYCLERAMA 530 Cam takes care of this beasts heart beat.
After the build is done, I get to work on the DYNO JET dyno, tuning it up & getting ready for the drags. I was happy with the initial dyno results (142hp 137ft/lbs) but I'm not finished yet! New air filter to go on along with a few other changes & I'll see what I can get from it.

I did same thing with my 2018 Softail low rider. Straight from dealer tore down installed SS 124 kit with fat cat. Man that bike ripped !!!!
Awesome bike
That sound @5:52 Amazing
What could I expect as far as cost wise for something like this from Harley?
I can't say for sure exactly how much it would cost as I'm a Technician & not in sales, but to give you a rough idea,
This particular model (FXLRS) retails in Australia at around $27,500rrp, then the engine kit, Upgraded 2 into 1 exhaust system, Upgraded Air Filter, tuning device & build labour costs would see a total cost of around $38,000 Australian dollars.
I have same bike apart from exhaust and air cleaner ecu. I think making it faster
I still have my stock heads (114) on my 2020 lowrider s. 8+cam, some push rods, Rekluse clutch, big boy hp inc throtttle body, thunder header yada yada and my numbers were 136 hp 149 ft lbs on the dyno
I think at this point I could do 124 heads before I’d have to change out cam etc.
This one ended up making 158hp & 154ft/lbs. Video is on my channel. 2020 Benaraby drags. This video only showed a basic run in tune. It's crazy how the M8s make heaps of power very easily compared to the twin cam.
Yours sounds like a gret combo. I've tried a Rekluse clutch in a 124ci Fatbob. They work great however, when it comes to drag racing with one I didn't like it as trying to flick the clutch at wide open throttle to grab another gear proved hard as the centrifugal properties of the Rekluse made the lever very hard. A pingle quick shifter and Rekluse would a mint combo
@Paul Mears ruclips.net/video/AHm-VOuRWGc/видео.html here is the link to video making 158hp & 154ft/lbs
Master Tech Miller true about the clutch. One thing I know the Thunderheader really ads some torque unfortunately with this 833 cam it makes this exhaust like riding the wing of a f18 it’s so loud it’s almost unbearable
@@paulmears825 Oh true!? That's a shame about the excessive noise.
I'd love to try the new 2into1 from Thrashin. Looking like a great pipe from all the reviews I've seen & read.
Paul, was this with a 124 or 128 kit also 136/149?
You didn't make the hone of the engine and you run it on dyno?!
nice unboxing looking forward to more build videos and one thing you might want to consider switching Gopro audio to mono in the editing keep up the good work
Thanks for the feedback & tip. I have another video due to be uploaded in 3 days time. I'll give the audio a tip a try next video I film 👌👍
Thats some good bhp from that kit.What would the kit incuding the exhaust cost?
Alpha Performance Engines are doing the cylinder & piston kits for $1800 at the moment on special. The cam shaft is around $550, cylinder heads $1000, The D&D Fatcat was $1900 & the air filter was $700.
harleys aint slow anymore 😎
they havent been for a while. It just takes more money to truthfully "wake" them up. not everyone can buy a brand new bike, make the down payment, and then throw another 5 grand on top of that. even though we all wish we could. im working towards being able to throw 5k at my late 90s wide glide to get these same kind of numers.
only after dumping $4k into it!
@eugenescoj hey man, gotta pay to play!
What CAM did you put into it? Sounds very lopy I love it.
Cyclerama 530 👊
Could I use that on a 114 with a stage one, or do I need to do a 128?
@@chrisnj7587 unfortunately the Cyclerama 530 is not a bolt in cam. You need to change the valve springs to suit the higher lift. I've not tried it on a 114ci yet but I don't think it would work very well as the 114ci would a fraction too small to benefit the cams potential.
Balancing 300kg of black beauty one-handed at 2:11 is second-nature to this bloke. Thanks for sharing a great video! :)
Thanks mate. Going on 14 years this November. Still love every single day of it!
@@MasterTechMiller That's a pretty gnarly specc'd machine ... Your choice of hand-picked components has really transformed the base 114 M8 into a Monster. Just out of curiosity, how much does a kit like that add to the price of the bike (supplied & fitted)?
@@Jonathan-L that particular engine kit, including, air filter, pipe, tuning device & labour to fit it is around $6500 ride in ride out.
What is the part number to that D&D Fat Cat exhaust?? Looking for that EXACT pipe for my 2020 Lowrider S. The D&D Fat Cat that I find are slightly longer and sit closer to the ground, they don't have that slight bend upward at the end like your does. GREAT Video! Part number plz.
My bad! It's a D&D LOWCAT! I wanted the FatCat but ended only being able to get this one at the time.
@@MasterTechMiller Thank you for the reply. Can you tell any sound difference between the FAT and LOWCAT? Is one loader than the other? Is it a quiet or loud exhaust? Hard to tell an exhaust sound over a PC speaker.
@@michaelscott7482 This particular build has quiet a bit more compression than stock so the exhaust note is fairly loud at Idle and when your really into it. At cruise speeds it's actually surprisingly quiet.
I haven't heard the Fat Cat on a similar build so unfortunately I can't say if there is any difference between the 2.
What I can say is I prefer the sound from this Low Cat over the TBR & Bassani pipes.
@@MasterTechMiller Was the Lowrider S lowered when this video was recorded? Or was it lowered later?
@@michaelscott7482 It was lowered after. There is pictures of it on my Instagram @tommy_twincam_miller
omfg
Great work. Might see you up at Benarraby.
For sure mate, I'm keen as!
What do owners do with all the stock engine parts,pipe. I’m 5’8. No question that the Lowriders are a top bike.Always torn between one of these and a Sportglide. In 2021 for an extra $1,500 you can get one in a venom green.
Most customer take all the stock engine components home and attempt to sell it online. There is not a huge market for stock H-D parts. If for some reason a customer has a stock H-D and is in need of a rebuild they will normally upgrade from the stock configuration to something different rather than rebuilding it back to stock.
Other customers tell us that they don't want the parts at all.
Great video. Can you please bust the myth...... Is it neccessary to break your bike in for the first 1600kms? I see plenty of videos where people dyno tune them straight out of the box. Does this reduce the longevity of the bike?
Probably a good idea. The tuner I go to will do some “accelerated” break in runs on the dyno, change the oil, and then do some runs.
The accelerated break in is just running at different rpm’s under light load for a couple heat cycles.
How much is it for this upgrade
What fuel injector size are you using for a build like this? I’ve been told 5.5 is fine, others say 6.3.
This one had the 5.5gps however we commonly use the 6.2gps injectors because the duty cycle of the 5.5s starts to max out when using larger cams.
142/137 are great numbers. what tuner are you using? Cheers

@Master Tech Miller Can you please verify the model of that D&D Exhaust.... You state it's the Fat Cat, but it looks more like the Low Cat model, which has an upswept design.
It's definitely a Lowcat.
@@MasterTechMiller thanks for verifying
Amazing knowledge and skill, what a sick bike. Do you recommend anyone in Sydney who can do similar work ?
Thanks for the great feed back! I can recommend 'Maros Customs'. Tell Luke I told you to see him and he'll look after you.
@@MasterTechMiller Thanks mate
Ive been looking at buying a Lowrider S but was hanging off until the SE 131 was available for the Softail. Interested to talk to you about this option.
You can easily build the 131ci engine for a Softail. As you may be aware, only the 131ci crate engine is availble for the touring models.
The cyclinders and pistons (4.310") are available through Screamin Eagle and will take a 114ci to a 131ci or a 107ci to a 128ci.
Everything is the same as the crate engine except the cases obviously (to suit a single balancer on the crank of the tourers).
If you wish to talk more in depth over the phone, give me a call at Darling Downs Harley-Davidson 0746 342766 🍻💪🏍💨
@@MasterTechMiller Will do mate
I love it!!
I see you use Hd head bolts do you torque them per manual and do the 90 degree or per s&s torque sequence
I torque them to the UPDATED torque sequence from Harley. Instead of 27ft/lbs then 90° , It's been bought back 20ft/lbs then 90° after the initial 'crush' then back off 1 full turn and creeping up to 20ft/lbs in 5ft/lbs increments.
@@MasterTechMiller thank you getting ready to do my 128 build
only the bravest of men will install gudgeon clips without a a rag covering the big end.
Nothing to worry about with the Harley's. Only a crank in there....easy enough to reach down with a magnet should you drop something in there. The C-Clip installation/removal tool from H-D works an absolute treat 👌
@@MasterTechMiller good to know! I have only ever rebuilt chook chasers and a dropped clip would quickly turn a new slug into spilt cases and a whole lot of swearing.
@@HamishBrown3yeah absolutely!!!! Can imagine! It's lucky with the Harley's as I said because it literally can't go far at all. You have plenty of room to see straight down in there 🧐
Ouch! 👍
What size Cam ?
ok found it cyclerama 530
Cyclerama CR 530. It is no longer available, the new Cyclerama CR 540 is the we use in all our Hi Output builds now
@@MasterTechMiller ok Thanks kindly i will look it up
What camshift are you running in it?
Cyclerama 530. Final tune made 158hp & 154ft/lbs. Video is on my channel
@@MasterTechMiller That’s kicking butt. Changes made? Extreme AC, 64TB & factory ported manifold?
Why the Lowrider S instead of the FXDR in the earlier videos?
Because I work at a Dealership and every couple months I get a different model to play with & build. Pretty lucky really, not too many guys I know at Dealerships are even allowed to ride there demos, let alone build one up & race it
@@MasterTechMiller Living the dream, mate. I was wondering if there was a performance benefit/difference between the models.
Oh ok, well both bikes started life as 114ci Engines. They both had 128ci Alpha performance engines cylinder & piston kits. Alpha Performance Engines Stage 1 Warflow Heads & 55mm Intake Manifolds. The FXDR ran Bassani 2into1 & the Lowrider runs & D&D Lowcat. Cam shafts are different too. Cyclerama 530 in the Lowrider FXDR had a Cyclerama 470 from memory. The FXDR made 140ish HP & this lowrider makes 158hp
@@MasterTechMiller I guess what I'm trying to ask is, between the Lowrider S and the FXDR, is one a better platform for turning into a drag bike with regards to geometry and weight...etc...?
@@buck_the_atlas oh sorry mate,
The FXDR would be more suited for Drag racing in the geometry aspect
Im curious as to why you didn’t choose the Harley factory 128 kit instead of the aftermarket?
The Screamin Eagle 128ci kit uses 4.310" pistons in both the 107-128 & 114-128 kits.
When bores become larger, ring seal is very crucial. Unfortunately Screamin Eagle have tolerances that they machine to & the products are produced on a much larger mass produced scale therefore allowing for many differences between measurements.
Without torque plate boring & honing, the SE cylinders are easily subject to large out of round measurements.
The Alpha Performance Engines kits are produced to a much higher standard & because they don't mass produce the kits on the scale SE do, they are able to retain a much higher level of quality control.
The APE kits use 4.250" bore on both 124ci & 128ci kits, the Stroke between the engines is the only difference 4.375" on the 107ci & 4.500" on the 114ci.
We have found running a a slightly smaller bore with a precision machined cylinder provides much better & more efficient ring seal properties. I can go further into detail about the piston design benefits of the APE kit VS the SE kit aswell but again, it all comes down the the scale of production and higher level of quality control impossed by APE.
Longevity & performance is the name of the game & I feel that SE does not meet my own level of expectations to tick the boxes.
I hope this helps answer the question?
Let me know if I can answer anymore questions you have. Cheers!
Master Tech Miller thank you for the technical information. I see your points and I believe them to be sound. The only concern with the aftermarket is the the voiding of the factory warranty.
@@roadrash76 yes absolutely that is a concern of most customers however the factory warranty is VIOD if an aftermarket tuning device is fitter. SE only offer their Street Tuner Pro to tune there big bore high performance engine kits. The Street Pro is VERY limited in it's adjustability and will not allow the tuner to change target air fuel ratios and only allows for 5% adjustment on the Volumetric Efficiency tables.
When it comes to high performance engines, you definitely need to be able to change the target AFR & adjust the VE tables much further than the Street tuner pro offers.
With that in mind, customers can make their own choice on which way to go.
A well built and tuned engine will not show any signs or worrying concerns should the warranty need to be exercised.
Sending a freshly built engine to the dyno seems a little odd to me. No breaking in before putting it to the test? I do 2 oil changes (After 50 and 1600km) and a careful increase of rpm before I can set the new mapping and really let it roll.
That's the beauty of video editing & RUclips mate. Thing happen between scenes. I didn't think it was worth showing a heat cycle session, ring bedding runs & AFR trims. Just want to keep the video full of as much action as possible
You have part number for the CP piston ?
CP make those Pistons for us at Alpha Performance Engines and not available from the CP catalog. You can order them through us at A.P.E on our website or FB page 👌
The closest thing you'll get from CP is BHM8128-7 they are very similar but not identical to the ones CP make for us at A.P.E
@@MasterTechMiller can i not go direct to them ?
@@allan9584able You might be able to? I'm not 100% sure.
Awesome build! Did you use the supplied D&D gaskets for that pipe? I’m having hell trying to get my Billet Cat to not leak at the heads with their thin gaskets
Yeah mate, sure did. Haven't had any issues with before or even now?
