Can you imagine if Harley would just ship out the new bikes with the best parts to start with. I am burned out on spending thousands to get the power they should have had in stock form.
James dulaney You could say the same thing for pretty much any manufacture of Motorcycles or Vehicles.
Indian bikes come from the factory with basically stage 2 everything for half the price. Pretty sad actually.
Harley does it as a marketing plan. It makes a ton of money for them. And it works since people are never satisfied with a harley to begin with. Which is why we modify them.
You guys are wrecking my sleep habits. Up to 1-2 watching your videos. And some watching for the 3rd time. Nick and I have spoken numerous times. Look forward to visiting you next month!
Fucking hilarious. I have the same issue cause of these videos!
@@Bayonachris me 2 lol

Good info guys. Keep the good Videos on performance coming !
Branch & O’ Keefe and RB Racing! I gotta hear this thing! 👍
New to your channel, but love all the videos. Keep them coming
Just put 55intake 475 cam chest stealth air cleaner power duels all S&S IN 107 22 STANDARD. Dynojet power tuner. Picking it up the 19th .. wish me luck ..
Nailed it on the explanations!
Lol. Calipers are +or- .002 from the factory. 👍🏻. Lots of info. I like the HPI throttle bodies. Which I think I will be putting on my bike.
That bike behind them though!
Thank you for all the information you provide, love the videos. I can't afford to start braking parts on my bike pretty happy with the upgrades I did, please let me know what you think. 2019 RGS with RS468 cam SE air Rinehart 2 into 1 Thundermax tuner. I ride very aggressive 😉
Like hearing about all the differences in the screaming eagle and the aftermarket. Getting ready to start building my 107 and want to get the most bang for my buck
We would recommend our 126 setup with heads!🚀🚀🚀
Cant wait for the next vid ! Im dyin over here
You'll lose it on this next one haha
Just subscribed and am addicted to all your vids 💪
So you are one of us!
Finally a video from moonshine I was able to watch. Was about to click of when they said the idiot was not going to be there 🤗
The HPI costs around what? Well done video. Explained very well I might add.
Moonshine Harley, does either the 64mm SE or the 62mm HPI eliminate butterfly valve clapping/chatter/knocking that comes when you put a cam in like an S&S 475C? I put that cam in ('20 Road King Special, 114) and now have that butterfly valve knocking and am wondering if an aftermarket throttle body can make that noise go away or lessen it. Thanks and love your channel!

will harley m8 air cleaner kits bolt right up with the HPI and fuel injectors ?
Man you guys are pro's wish i lived there and had you guys build my Harley.
wally cleaver We have bikes shipped to us monthly, we build them like we do and ship them back. If you’re interested in having something done we’ll work with you on the transportation. Please call Aaron or myself Jamie at the shop so we can go over the details. 615-771-7775.
Outstanding video. Thanks for the truth - instead of the million opinions you get on the forums.
A larger throttle does not hurt low end. That plenum could certainly change the flow rate and velocity. A larger throttle body would make tip in throttle much more aggressive though. That little bit of difference isn't changing much anyway. 62mm will flow way over 150 160Hp.
I am wondering about the trask turbo system. Are they actually worth the cost of the turbo? And what kinds of mods must be done to the entire drivetrain? I would imagine you would need stringer internal engine parts and maybe swap the belt for a chain, and some other things that come with stock bike.
Screamin eagle 131 heads with the HPi what’s your thoughts and what size total for it 62mm set up as 62mm? I’m going with Klock Werks Outlaw 2:1
HPI are the best and made right here in the USA, been using them since 03
Aggie Frazao AMERICA!
Your right the the TB has to be really matched up to the rest of your build....and it’s not how fast you go it’s how fast you get there lol 😝
Thanks Fellas! You get any calls from da ladies wit dos phone numbers?
I recently picked up a 64mm SE TB, I only paid $300 for it. The HPI unit is just too expensive, especially considering that it still uses the oem throttle servo motor. I suppose if you're building a big ole mountain motor or something you could justify the added cost.
@moonshine 02 ultra 95 big bore kit,635 cams ported and polished heads, have a 06 tb on it right now,what would you recommend for tb size
I love the stuff you guys are hitting on/I suggest though that you use a 3 point digital bore gauge not a caliper to measure bores.i work in the CNC world of +\_ .0002 everyday and would slap a bitch for checking diameters with a caliper.other than that you guys have a cool gig rolling (keep it up)we out here depend on that knowledge your putting out
A Ninja We would but the measurement was a reference and we wanted you guys to see the data. We already knew the diameters!
Do you plan on releasing the dyno results between the HPI as is and Okeefe ported TB? Thinking of using the HPI with a set of match ported and blended SE heads on a 124” @ 11.5:1 with a TTS250 or Tman 234 cam. Very keen to know if there was any significant differences between those two TB.
Was wondering the same thing, never saw results on the ported TB. Eric how did your build turn out❓
Do you or Harley warranty everything you do?
Curious what pipe you plan on using which can make a big difference as well.
Hugh Snyder check out our cam shoot out videos.
Every show the dyno numbers on these? I'm getting ready to do Branch heads with the 62 mm TB on S&S 131 jugs., S&S 550 . What pipe did they use. Is Supertrapp's 2 into 1 good ?
I would call our shop and ask for Jamie 615-274-4170. We have lots of dyno charts posted on TH-cam and insta. We now fun out 66mm intake with a 64mm Throttle body with out ported heads. We now only run the 62mm setup on cam jobs.
Shake - N - Bake!
i subscribed just for the ricky bobby reference
Moonshine what you guys think of basani road rage 3 for baggers as far as performance?
Collins Hands It’s not a pipe we use.
What do you guys think about the SS 55mm aluminum throttle body to replace the plastic one on my 20’ 117 CVO with an SS 475 cam and Khrome werks 4.5 mufflers with louvered baffle and fuel moto 2/1/2 head pipe
Harley 64mm manifold and 64mm Throttle Body. This is the setup we run on most of our stage II setups. The M8 want more intake even on these cam swaps.
Would the SE 64mm tb and intake also work well in a 114 with a wm8 22xd cam? What about injectors?
What air cleaner would work with it? I have one similar to one on bike behind you but it's an HD performance part when I did stage 3?
sokodad you’ll be fine!
Were can i get the red tb
Dial caliper reads 1.780 diameter...Pronounced 1 inch 7 hundred and 80thousands. You guys are saying...1.078 dia..... Pronounced 1 inch 78 thousands.Almost 3/4 inch diff. I play a machinist on the interweb LOL Love the channel!!!!!!!!!!!!!
Results?.?.? Which made better numbers?…
I need all the torque for my 114
Is the bike done yet? I'm not seeing it anywhere
We put these on a lot of customer bikes that want this performance upgrade. We'll have a video in the works with a specific bike, this was just to cover the overview of these three throttle bodies and the use cases of each.
Do you recommend the hpi over screamingeagle. I just did a 128 m8 build from fuel moto
@@heathmitchell2086 it depends. We try to match the throttle body to the heads. When we run HPI we usually port match them. Did you do anything with the heads? There's more info and easier to answer questions at @m.v.o_motorfast
so what should I use with a 110 tire shredder kit 🤔 👀 😳 HD NEIL AKA THE KRONK
HPI 58mm plus we would swap the cam for one that’ll run!
@@MoonshineHarley even with 259 e screaming Eagle cams
Heritage or lowrider s. I can’t decide
Its pretty widely known that a smooth surface does not flow air over it as well as a surface that is not smooth or textured. Example: a golf ball, offshore racing boats hull design, 24hr Le mans, formula 1, and many other markets where science dominates "opinion".
Dimple the flow path like a golf ball. Makes everything better... Flow, velocity, and turbulence.
What size throttle body comes stock on the 2018 Heritage Classic 114 Anniversary edition? Mine already has the Screaming Eagle Ventilator Air Kit... If I switched to something like the HPI 62mm throttle body, would I be able to keep my existing cleaner or would I have to buy something specific to fit the HPI model? I'm looking at doing a stage IV upgrade with the S&S 114 to 128 Big Bore kit, along with the S&S Camp Plate, Oil Pump, 550 Gear Driven Cam, Lifters, High-Lift Valve Springs and Tappet Cuffs. My focus is on as much low-end Torque as possible. Do I need to upgrade the throttle body as well, or is the stock version on the 114 big enough? Also, I had new lifters and push-rods installed when I got my Stage 1&2 done last year... but that was for a TTS-100 Cam... Should I replace those again with S&S specific parts? Any help is appreciated!
The ventilator is not a good air cleaner. If you like that look the ventilator extreme is ok. Be careful what you choose for exhaust to keep the power low. Especially with the S&S 550 cam. The S&S valve train components are good. So are the Feuling. Those are the two brands we usually use.
Did Aaron used to be at Kutter?
I don't know. It's it in California?
That’s a different Aaron
Ride 2 up tour pack on it and I rode like a stole it a lot LOL hahaha
You die once, but love every day might as well live it and enjoy it.
Fkn beasts brothers
You guys should do shows on TV like horsepower TV do twin engine builds I'm sure you will have a lot of ratings a lot of viewers and make sure the host is a fine women that doesn't mine getting dressed up looking fine as hell that also helps there is no shows like this Twin power TV is a must plus help benders sale products and Harley's to i want a new bike for my wonderful idea street glide with 131 build i like hogs and can be the first show
Did I mention the host should have big boob's and a fat a$$
So your saying you have a smaller head.😆
good video..... let Mike do them! you guys have terrible acting skills! Love your channel!
😂🤣 Good thing we are not actors.
Bro 😎 come on it’s not Jamey it’s himeh Jaime jaimito
"Cams and intakes are a black art"
Uhhh... no they're not.
F me I guess.
Never understood why you'd spend all that money on the bike to begin with and immediately start looking for power that the bike should have had in stock configuration.
America.
@@MoonshineHarley ok , name another bike brand where such mods are required to hopefully produce more power ?
@@richardmerrifield8186 all bikes make more power with mods. Its more of a want than requirement.
Never understood people who bitch about what other people do to their bikes on the Internet.... not everyone wants a lame stock bike, meanwhile others are perfectly happy with a stock bike.
But one of the selling points to Harley bikes is the ease of modification and massive aftermarket support. No other brand has any where near the amount of aftermarket parts available for them. You can custom fit the bike to you and how you use it... mean while get a Honda, Kawi, etc... you can get a seat and exhaust for them and really that’s about it.
