128 cu in. Milwaukee-Eight | Dyno Tune 

I love how in the opening scene the bad ass running the dyno has no ear protection wide open 😂

I love that sled/ anything negative is only Jealousy

So refreshing to see a “dealership channel” doing work on YT. Always a great video with good content. Also, can I ride it...

Man it didn't take long for the Harley haters to come out the wood works wish people would just enjoy what ever bike they choose if you don't like "insert brand here" don't watch those videos if your that butt hurt over someone else spending their own money on something they want

Well, I think they are very respectable numbers. I am sure more could probably be squeezed out of it but at least the way you have done it means it'll be reliable. I know the numbers are just that - some make more, some make less and different pulls on the same bike with the same tune can give different numbers on the same Dyno - been there and done that. I think that what is refreshing is that this video was done and shown publicly - your honesty is so refreshing ! Remember though that it is not out there on the road, and often less powerful bikes are faster if they have better tyres, suspension or a better rider......

The bikes makes what it makes. That's a very respectable number. Great looking bikes thanks guys.

My dad purchased a 2019 SG CVO with 1k miles on it from Barracuda but passed away unexpectedly, so now I'm having the bike shipped up to me to have the 128 SS w/ 550cam put in along w/ some other very unessecary upgrades. Can't wait.

Wicked. Them some smooth outputs. Dig it. Cheers.

Thoes are some hard working hands!! One of my uncles became a citizen after almost 30 years but his labor job of gardening took a toll on his hands and finger prints. He couldn’t get his citizenship bc he didn’t have finger prints. Took him a few weeks.

Nice numbers. With the additionalhorsepower without fully water cooled, how is it in traffic.

I watched a video on one of the "king of the baggers" bikes and you have the same exact horse power but they have 143 torque. I guess one big difference is, the K.O.B bike weighs 300 lb less. Awesome job with the bike. I enjoy watching your videos.

LOVE IT. Great job guys. Damn thing is a BEAST

Been waiting on this one!

I have the 128 on my '17 Limited with a Woods cam. 131 HP and 147 Torque. She's a fun bike to ride.

Dyno tuning is amazing. The numbers are neat to see and are a nice thing for people to bench race against each other. But the real bragging rights is when it comes down to a street light grand prix with a fellow motorcyclist. That's how you put your money where your mouth is

A little late to the game with this comment, but great video guys. I love how to the point you were haha

No one ever lists the cost to build one. What is the complete cost from stock to make that power?

That bike is badass 👍🏻👍🏻

So what is the build spec, was never posted in other vid?

Good video thanks for sharing

I believe you. My 128 got 138HP and 140 TQ on the Dyno fresh after the rebuild.

What tuner are you using ? And which cams ?

Are these numbers corrected or uncorrected hp & tq? How much compression is it running?

Well done! 🙌

Woooow that's amazing I need this mod on mine

Awesome video.....👍👍👍

Nice bike! Hey what bars are those? Thank you great video.

Not bad for a Harley kit that I’m guessing retains warranty? A competent Indy can for sure push near 160 hp/tq with high compression and good porting/ cams and throttle body.

I have a 2017 ultra limited with a 128 kit, on the fly tuner2 into 1 into 2 head pipe and screaming eagle mufflers all done at a dealer and dynoed at the same dealer in Oregon late last year. I spent after the discounts 7000.00 and have 109T and 108 hp so 120 is not too bad ...... I am not happy with what I have but after my extended warranty is up I will do something with it.

Where did you get the 128 badges at ?

Is this 128 all SE parts?

What cam is this engine using ?

G'day from Australia, nice video and that's a nice torque curve good work I bet the thing pulls hard👍 and to all the people on here knocking the M8 if you don't like it don't buy one it's easy, I bet most of you haven't even ridden one you just look on the forums all day and memorize every little problem they have so you can recite it and sound like an expert to your mates to strangers at the coffee shop haha. Maybe if you Road more and spend less time on the forums you wouldn't be such a whiny old bastards, every new platform has teething problems that's why you have warranty to fix these problems and they get fixed. Yes I do have Harleys I have an Wide Glide shovel, a knucklehead, a 2003 Softail Springer, 2008 Night Train, V rod Destroyer , 2013 Dyna custom, and 2019 Road Glide they're all on the road and they all get ridden and the M8 by far has the most power and Pull out of the lot ( except for the Destroyer) and way more comfy to ride that anything else so before you all knock em how about you just go and ride one🤙

I may have missed the episode, but did y’all post episode with the parts list, I’m considering going with a zippers 124 sleeper for my RG but also if I should with SE or aftermarket

What front fender is on the bike ? Thanks

Those are more impressive numbers than the 131's I've seen

Nice guys.

I have the same bike 19 RGS billiard blue mine does not roar like that but I’m looking into this

I'm not bashing anything, However, the initial pull in this video took considerably longer to hit the rev limited than the second and third pull. Were you doing something different or were you in sixth gear on the initial pull and then did the second and third in 5th?

Will these parts and upgrades work on the 2017 Street Glide CVO 114"? Do I need to the Harley upgraded Valve Springs, 64mm Throttle Body, High Flow Injectors, etc...Seems they want 2700 plus more$ for other needed parts only to increase this to 117"....

Dam! Head work also?

Nice build ! That rain sock didnt help anything though

Is Harley building bigger engines to cover up the Electric Scooters they built?

Love the flat torque curve.

I'll take it!

I love it 👍

What color code is it?

Numbers are just that. Numbers.... all these people comparing their numbers to this is amazing. Some people just dont get it. Dynos are a tool for tuning.

What gear are the dyno pulls done in?

I've seen a 2017 Road Glide with a 128 build pull 158tq on the dyno. Haven't had a chance to ride it yet because the roads here are covered in road salt.

Thx for your honesty. I now know that I won't waste my hard earned $ on this set up.

How did you get the 128 displacement ? From a 114” start ?

Still a strong bike.

What tuner ?????

I'd like to do a build like that on the new Low Rider S or Fat Bob, that would try to tear you off the back.

Thts good shyt guys...get down Harley...!!!

Install a Bob Wood M8 night prowler cam and you will blow those numbers away...

Just bought a 128 kit. And i ride a street bob, which is 100-150lbs lighter than most other harleys. Cant wait till fuckin spring. Bout to chew me up some crotch rockets

There is a 151ci kit out claim over 200hp 200tq

Good video,, have guys done a 120 R?

atmospheric pressure at sea level is around 14.7 psi not sure where 13:1 comes from

Haters are just jealous! 😂🤣 Great numbers!

I live just over in Tampa, Bert's Harley...is this bad boy for sale?

good video throw a turbo on it

Good #'s but if I'm reading your Dynojet sheet correctly, those are "numbers at the engine". I love Harley's I'm on my eighth, most of us are interested in REAR WHEEL H.P. & TQ. #'s. My calculations may be off but your HP at the real wheel is more like 115--117 and TQ at the rear wheel is more like 118--120. Still good numbers.

my 2000 road king, converted to road glide, with a jims 131 motor tops 150hp and 160 lbs torque, only cost the guy before me 26k in upgrades. LOL

Great numbers for a lighter chassis but not optimal for an 800 lb. bagger. But hey, it's not my money.

I need it

Numbers aren't stellar, but I bet that torque curve is fun to ride?!?

Hey Guys, I'm in the market for 2020 Road Glide. Im looking do something like 128 cu in to it.

My name which was Paul King ( until I changed it yesterday" was on the 0.44-second mark of the video. I wasn't claiming to be an expert. I was just saying " Holy .....Fuck" as I was impressed and liked the motor. But I did love seeing my name in the video.LOL!! I have a Stage 3 107 M8 and been interested in buying a crate M8. Anyways sorry if you misunderstood me and thought my Holy ....Fuck...meant I was an expert.;-)

That thing should be in the 150’s... Ported Heads? What cams?

Sick. 130 hp 130tq. Sick with me riding it I'd smoke anyone on anything anytime or anywhere

I'm sure this bike doesn't pass motor oil into the primary or suck it from the transmission? Hopefully the valve seats are nice and tight in the heads and dont come loose rendering low compression. Or have oil pump issues due to sumping and causing the motor to blow?

Now slap a trask turbo on that bad boy

The problem is dynos are not all tuned and calibrated the same... what your shop gets it wont get in another shop... in other words most places lie about the numbers... and have the dyno calibrated so it makes more hp and tq... so who cares what numbers are... if your happy with how it performs than that's all that matters

My twin cam 107 makes that power .

That is a shit load a of torque.Very nice.

Would like to see an engine swap. R1 1000cc engine into Road Glide.

You should do a video where you fire Dempsey--- out of a fucking cannon. And then he lands in the back of a late 90s Nissan Sentra and lives happily ever after.

And to be clear, that bike in the video is awesome, but if you’re gonna do that kinda build.....and spend that coin, piece together your parts because you can get more power and cheaper just machining stock parts.

Sorry I wanted to watch the video but video played for me at 360p, that's makes it hard to watch.

Yea but is it dependable?

I'm glad mines a 124 and still out does that bike. 142ftlbs and 148hp. Better parts

Almost as good as a 10 year old victory 116 lol

if Feul Moto did it, it would be in the 150 RANGE

"before we go to the dyno we had to put 1000 miles on it". Absolutely the wrong answer and a great way to permanently damage ring seal.

If you could get 250 hp out of this bike with modifications and it would still ride without problems I’d get one.

It no longer matters. The HD motor company can not just lower prices. We now have access to Harley corporate balance sheets. This motor company in the red by almost 500 million. They are forced to sell bikes with substandard parts, just to generate the "shop-income" in some veil attempt to service some of these loans. This company in such a death spiral, is now only a matter of time before the banks start calling them in on some of these loans.........

After just watching the first video and now this one I've come to this conclusion. There's plenty of fucking experts out there, sitting behind a keyboard. The dyno pulls wont shut them up. You cant teach them anything because they know every fuckin thing already.

Some will talk shit because they can't get those numbers or they just haters who just bitch about everything if they weren't the one's to come up with it first.

Even with this upsized motor, this HD still doesn't make enough horsepower to surpass a standard BMW GTL K1600 which costs thousands less...

For people looking for numbers?zx14r 210 hp I own one and for harley lowers never understood why spend 30k spend another $$$ for extra ponies??? I own tree Harley’s before and I enjoy riding looking for speed and hp don’t by harleys not design for

A 117 victory puts down these same numbers... from ten years ago. A stratoliner from 20 years ago WITHOUT a expensive ass big bore kit gets 126 torque lol. Gotta love the harley fan bois and that money to burn.

You spent $30.000 on a Harley most likely financed it then spend another $10.000 on performance upgrades just to make go down the road .... still a air cooled pushrod motor!!

Does everyone know that dyno numbers can easily be messed with. It’s all in the setup of the dyno software, want bigger just change a few settings.

just buy a Kawasaki concourse 14 165 hp BEAST of a cruiser for 13k

So much money....so little hp ... so glad Harley treated us like shit shut down factories went overseas and sold us outdated technology. So I went to bmw stock 160 hp 120tq with o headaches.

...buy a Kawasaki
