Harley Davidson M8 107 TO 128 STAGE IV KIT!!

In this video I show the process of taking my Softail Standards 107" Milwaukee Eight to a Stage IV 128! This bike was fun before but absolutely rips now! I am VERY impressed with the dyno numbers to say the least.

I did the SE Stage IV on my ‘19 FXLR going from 107 t0 128. Worth every penny. It is a night and day difference in power and torque. The 107 is fine but I just couldn’t resist this upgrade to 128. It easily gets around 40 mpg.

[@user-hx1eo6dz6r]

More power never hurt anyone...may not need it, most won't use it..but it's nice to have it...( some of us will us it , whether we should or not😂

[@wicklowjohn]

“Yeah I’m not going to nail it” “hold my beer” 😂

[@throttleblip9854]

I owe it to you guys! haha. I do it for y'all not for myself lol

[@shaneshuler7151]

I have a 128 SE kit on my street Bob it’s probly the greatest thing I have ever ridden wayyyy too much for the normal rider but when you want it to go it does, it takes a special breed of riders to do it and actually ride it properly the way it’s intended, good tires and full suspension makes for a killer ride trust me

[@user-hx1eo6dz6r]

Ya quick way to puss u off when u go down the road and there is grass everywhere just left there, it takes just a extra minute to make a run or 2 and bliw it off the road....sadly most ppl either don't care or think about others possibly being in danger over it.....nice clip..I have the 2020 standard myself and plan to have this done.

[@MK87_]

nice bro! the bike sounds great. I loved my 122 in my LRS but im sure your going to love this just as much.

[@throttleblip9854]

Thanks man! Pumped on it for sure. Come ride it any time!

[@chrisderr9702]

I’ve researched so much “stuff” that I don’t know what to think about doing an external breather on my 2020 FLTRK? I am hoping to get your opinion on it. I feel you are one of the very few honest people on KZbin and value your thoughts. Looking forward to your reply

[@PunMidas]

Whoa that's a hell of a gain.

[@throttleblip9854]

I was very happy with it. Changing the pipe would help get a little more but not with another $2k to me. Haha

[@SCBiker58]

Good info, I went with just the S&S 475 and the Screamin Eagle oil pump and mount on my FLFBS. Timm’s did mine. I have a 5 gallon tank and my mileage was less but it was running a little too rich and Bryan at V&H tweaked my map and sent it back and It runs great, sounds great and is getting around 48mpg when ridden sane is how I normally ride being 65 years old. Plus I have the wife sometimes with me and we take shorts trips and I couldn’t deal with 25mpg. If someone is doing it to be fast someone once told me years ago “There will always be somebody out there faster” so I for one found that out decades ago and never try and go the lets be the fastest route 😏. One point on those that try and drop the idle down really low on a M8 should be careful since you can starve the engine of oil getting to the needed areas. I think the recommended idle is 900 to 950?

[@TeensierPython]

I did the 114 to 131 kit. Loved it. Little bit of a gas hog though. Still kicking myself that I sold the dumb thing. Don't know what I was thinking.

[@nealmoyer7216]

I have a 107 with a 475 thinking of putting a 30/30 in, lower end torque

[@OnyxCVO]

Nice build. Good numbers. I like the 550 Cam better. I have a 128 on one of my Road Glides and it is Superb. I agree with you.

[@lastnline1]

Love the build was thinking of doing a 128 on my street glide

[@robertbarbaree4190]

Nice! It's a little more expensive down here. Closer to10k for the 131 and 15k for the 135 otd with additional parts and dyno time. At those prices I'd rather throw a cam in my RG 107 and pick up a 2nd "play" bike.

[@javonbrandon]

This bike going to be a beast on the roads

[@throttleblip9854]

It's insane. Waiting on my tires then I'm going out to look for some 131 baggers to run! lol

[@palmettolowlife1996]

@@throttleblip9854what tires did you decide to get and I’m curious, if you had a SE 122 FXLRS (All HD parts currently) and wanted to build upon it what would you put into it ? Cam, springs , etc. I’m trying to decide what I want to do.

[@palmettolowlife1996]

@@throttleblip9854did you strengthen up the cam chest at all or just using the oem pump and plate etc

[@throttleblip9854]

I went with the Shinko 777's. Cam would be my next move. If you do a big one definitely do the valve springs and adjustable pushrods.

[@throttleblip9854]

All stock cam chest. Starting in 2020 HD was on the 4th version of the oil pump so it's not bad. If I wasn't building another bike at the same time and spending money on it I would have done the full S&S kit.

[@JaysonBucy]

Happy for you brother, enjoy the ride.

[@throttleblip9854]

Appreciate it bro! Thing RIPS!!!

[@Nucklehead-mm9gf]

I love the build man! Looks awesome!! Is there a way to get chrome on all the polished aluminum parts? How? I want this bike but I'm considering just dropping more coin to get the Breakout considering it has everything I want already just need a few bolt ons and detachables like bags and windshield for trips. I'm really on a chrome tip lately, I just want chrome with the black backdrop. Breakout looks so good with the chrome on 2024 model and has the 117 engine, cruise control, abs, traction control, usb port, heavy breather, 240 rear 21 inch 130 front......so alot more of what I want straight from factory! I'm concerned about the Softail Standard feeling too similar to the Sportsters and not the new Sportsters but like the Iron and 48. I love my Iron so much but I want bigger, wider, longer and badder not the same 150 rear 100 front compact little bike. Breakout has the whole package I'm looking for but so expensive at $22k but after adding alot of things I want to Softail standard it comes put to about the same price as Breakout but still missing alot of what I want like bigger tires, cruise, TCS etc. OK I think I just realized the Breakout is clearly the bike I want so I need to just go for it. 😂

[@Fever_Rides]

Bike sounds great! And I blow grass on the road when I mow ditches. Unless you're going too fast around a curve, grass isn't going to do anything to your traction.

[@jonwragg3822]

Where are the other videos. Last one before this was a month ago as far as I can see. Rode a 131 Fat Bob from Reading Harley, UK. Wonderful.

[@roborracle]

Found this channel doing research for my own Softail Standard - outstanding stuff! Did you ever do a full walkaround post-upgrade video? Saw the new seat (same one I'm planning on ordering soon!) and a couple other things. just didn't know if you did a full before > after on her.

[@kristophergreen2418]

Great video!

[@kevinmacwatters1519]

nice and thanks openness

[@MrWhiteTank]

The perfect looking Softail standard Harley and sounds amazing! Gawd those #’s are great! Would it be similar if I ordered a Softail Standard with 128 kit from a Harley dealer?

[@jasperduncan6633]

Outrageous

[@LeeCampbell6581]

1 was about to say grass clippings where i live is a huge issue.....then i see you're right by my house! lol I asked for the specs and upgrades for this bike in your earlier video, i have the same bike and want to make changes/upgrades. recently purchased through boneyard, would love some insight from you man!

[@stolnpckup]

The only timms that i ever heard of is in anderson,SC.

[@ALPHAFTUCK]

Curious. I was under the assumption that a 107" could only except the 124" unless the crank is swapped because of the stroke difference? Cheers from Alberta Canada 🇨🇦 🤘🏻💪🏼

[@jackierobinson7043]

That’s exactly what I was told

[@geraldgoodiii6993]

I’m looking at doing the 119 on my 107 Road Glide Wait .. the HD SE stage 4 heads can barely take more cam than stock heads ?

[@jamessmart7605]

What shop did you use for the install?good work there!

[@trafficon2wheels]

nice enjoy Mexico, hope the bike goes to a good home, I have a spot for it…best

[@shannonmurphy314]

What’s top end speed on the 128 stage IV

[@user-oc5je8iu5r]

Hey try corsa like on Ducati there sticky but got heat up first

[@davebrake]

Great video, valuable info thanks. Been looking at doing the 131 on my 114 M8. Do you recommend the upgraded oil pump? Also you mentioned Dyno time. Is that ok to do at the time of installation, or should you wait until after some break-in miles?

[@throttleblip9854]

If it's in your budget it's never a bad idea. 20' models and up have the 4th gen oil pump which has proven to be pretty solid so you should be okay. It's fine as long as the engine has had proper heat cycles.

[@markhenry192]

Each to their own I guess but for me stock (aside from a stage 1 or maybe 2) is best if you want longevity and decent fuel millage!

[@illduitmyself]

Should just buy a goldwing then

[@markhenry192]

@@illduitmyself you could I guess.😃

[@stancartright4268]

You’ve probably answered this already,but. What bars and risers do you have on your bike? Thanks Stan🤘🏻

[@throttleblip9854]

The risers are Roland Sands Sector and I think I went with 9''. The bars are fly moto but I get them through Kraus because they machine the center out which makes the wiring MUCH easier to get through.

I have this kit on my 20' electra glide. Things fuckin wild honestly lol

Yea, though you were stage 3 guy . Lol. Nice ⚡️

I am. No issues yet. I’ve ridden it how I want to just to test it and it’s been great.

[@chrismohler6621]

🔥

[@geraldgoodiii6993]

The MoCo has send that kit to a few channels … Not one person used they’re crappy head pipe, tuner, or cam 😂 I wonder their thoughts on that I’m thinking the 119 for me. Less heat and less strain on the bottom end and drivetrain

[@throttleblip9854]

I wonder too lol. They never said I HAD to keep it as a kit soooo I just went with it. haha So far the 128 hasn't been super hot. we tuned it slightly rich which should help. However it's also only like 75 when I ride it though so summer will be the real test!

[@Osyrus48]

@@throttleblip9854 time for an oil cooler upgrade, my friend! They say, more power equals more heat. No way around it.

Is the 128” worth doing for 7k! I have a stage 2 setup right now

[@throttleblip9854]

I’ll say it this way. I’d 7k isn’t a lot of money to you, do it. If you’d notice 7k missing from your bank account, don’t do it. Which cam did you do?

[@CodyMcDonald89]

@@throttleblip9854 right now I have a fueling 472 setup made 119hp and 129trq.

Not sure if I should just spend the extra and do bigger cam and do springs on the heads for now.
