Love the videos man, I remember first finding the turbo yz a few years back and that was the reason I started to build my minibike, but I lost your channel and only recently came across it again
i dig that you managed to fit the turbo in without ruining the lines of the bike. i want to see this thing put down some numbers on the dyno, very nice work.
Sick bike man! What fuel pump are you running? I'm building a turbo 125 twin out of a cut down inline 4, and just starting to plan all the fuel system. Cheers
Oh yeah lol… This year I’ll actually be able to focus on that a good bit, I actually have a wheel speed sensor set up for wheel speed from a Honda CRF because they have a much much better tone ring than what the WR 450 F uses. It’s a 36 tooth count so it will allow for some pretty clear resolution.
Dude this thing is insane! Found your channel the other day and clicked this video as soon as I saw the notification lol. I'd love to see a dyno video on the new setup once you get it figured out!
Man nice job. This is the 1st video I've watched im a dirt guy all the way but this is sick. It so cool to see someone putting out content that knows what they are doing. Is this your 1st time with the top fuel hoop. I need to watch your engine buld video im sure that will answer alot of my ? Like did you lower the compression ratio i would think with running E you might have 2 because it takes more fuel but tubos and running ethenol it way different than cams and race fuel im used to
Thanks! Believe it or not I have a dirt wheel set up for this bike as well as I still pretty much ride it regularly on trails and in the dirt and the sand. as far as E85 goes, this fuel actually allows you to run a bunch more compression and in my case a lot of compression and boost and it takes it pretty well because the fuel itself is essentially like 115 in octane. Last year on my last set up that was making 100+ horsepower I did kind of have a hybrid version of the top fuel hoop, but it didn’t use a copper gasket. It was more so a compressor cylinder head… But this time it’s an actual top field hoop, which is a bunch better.
cant wait till shes dialed i want you to be able to bark the throttle and have everything happy i bet there will be a big gain in hp after you get everything worked out send it man these are built to take extreme abuse but i want to see a reliable 8o plus and itll be well worth all the work we didnt see good luck fuel tech for the W good stuff mint
Yeah, with this set up, the true intentions were to just make as much horsepower as I could… So I did give up a little bit of swing arm travel, but I’ve already worked out a modification that I could do to the hot side and cold side that would allow me to clock the turboin a more elevated position that would allow clearance for everything in regards to suspension travel
So ive just been watching some of your videos on this bike you should look into your gearing 130 hp isn't going to be very usable in a 250 pound bike and it tops out at 120 and you camt apply power without wheelies in 5th im just guessing but a sprocket change would make it a ton more street able. You clearly have changed some but play around with different front and rear i think going down 1 tooth on the front is like adding 2 in the back i could have that backward
Yeah, I honestly think I might have to drop a few more teeth because on my last set up that was making around 130 hp I dropped one tooth in the front which should be theoretically equivalent to three in the rear and then I dropped one tooth on the rear sprocket, so a total of four. With the new Big Bore kit, it definitely added more torque and now I have to compensate for that lol
@mohamedabada7101 the xr has way different internal gear ratios that still could be a little short especially with the hp different I could be wrong but this 500 is making about double the power I think of it like a car for example the higher the hp either the taller gear to get it to run highway speeds or more internal offset in gear ratio for example the difference between a 4 and 6 speed. In his he may need more than that even to compensate for the lack of internal operations and there could be options there also I'm not sure how big of a difference in gearing the Yzf 450 x woods bike has but I know it's taller
@neilorange4112 my xr probably is around 50hp with a stage 2 cam and with 13 40 it tops out at bout 100 or a bit more. Not sure but it's plenty for a dirtbike
I know I should watch through more videos BUT since its easy to ask: How did you manage the added power because even stock 450's blow up sometimes and they seem more fragile hp/cc than streetbikes. Did you get a custom billet crank with stronger rod and a longer rod than stock to have less attack angle, and are there any piston mods or stronger top end crank pins/offset pin etc? Some guy made 76-80hp out of a cr250 engine and needed an offset pin piston ordered from wiseco or wössner (forgot from which) to tackle harmonic balance issues at high RPM. Cheers :)
On my previous setup I do On my page. In the summer of 2023 It made 105hp to the tire on 15psi on a pretty conservative tune. Near the fall of 2023 I turned the boost up to 24psi and fuel flow calculations align right around 130ish HP. Unfortunately I couldn’t get it back on the Dyno to back that up because I burnt an Exhaust valve.
@@The_StreetSweeper got a 250i dynojet dyno at the shop I'm in north Carolina. My buddy's Drag raced for over 40 yrs little famous his name is Blake gann his son raced nhra prostock class motorcycles. Been building engines sence the early 70s.
Nah, I still run the stock OEM clutch pack count. The reason for the billet clutch spacer is that I run a clutch lockout mechanism that operates off of centrifugal force. It’s pretty tunable because it has a lever arms that you can put bolts and nuts on to have different weights or basically different engagements of apply force.
@@The_StreetSweeper tempting as it is my husky 510 with a turbo would be almost unridable it unicycles at any speed up to 100mph on knobbies now without yanking the front so ill just leave it as is and enjoy without the extra expenses and tinkle factor.. but carry on im interested to see how far you streach that Ha Ha..👍
You got some crazy bikes now dawg.
Haha thanks!

Yup, I actually will be switching to that. Just have to re-tap the cover for the right threads

Preciate it! Thanks!🙏🏼

Nice to see a clean install, looks stock from a few feet, its gonna be a blast i'm sure
this is the nicest "dirtbike/supermoto" bike ive ever seen bro
11:54 damn, big ass nitrous bottle just chillin'.
This is a great build can’t wait to see u riding.🏍️💨
Thanks!
130+hp on a supermoto has got to feel insane. That front tire is going to outlast the bike, I bet
Sick bike man! What fuel pump are you running? I'm building a turbo 125 twin out of a cut down inline 4, and just starting to plan all the fuel system. Cheers
Sweet build man, try squeeze a flex between head and turbo. 👌
Good potential with wheel speed sensors , ride height , and the fueltech traction and wheelie control

Great work bro! I've used the oven in my kitchen to warm up things...works well cause you can set the temperature and go do something else!
Cant wait to see this riding

That little laugh at the beginning of the video 😈
Full operating temp. Let it cool, then re-torque
He'll yeh brother that's going to be a ripper
🙌🏼🙌🏼
Looks awesome. That's going to kick ass. Just wondered if your exhaust is going to hit the swingarm though?
All the best

Heck of a good job mate. Can't wait to see you try tame this beast lol 👍
Hope you get 160whp out if it. Great build!
Thanks! I hope so too lol
It cant move enough air to make anywhere near that, especially with only 1 cylinder.
So ive just been watching some of your videos on this bike you should look into your gearing 130 hp isn't going to be very usable in a 250 pound bike and it tops out at 120 and you camt apply power without wheelies in 5th im just guessing but a sprocket change would make it a ton more street able.

You should run 13 40@The_StreetSweeper
Run 13 front 40 rear. I run that on my xr650r amazing for the trails and cruzing @The_StreetSweeper

Insane build 🤯🤯 But whats up with the front disc brake? Diameter looks normal for a Supermoto, but the contact area seems so small🤔
Yeah lol… been meaning to upgrade that. 😅 in reality I’ll probably end up converting to a Brembo set up.
That’s awesome bike man I want to turbo my gsxr 750
Wanna see you ride it. Nice job 👍
Riding vid will be uploaded this week!
Amazing!
Thanks!
Do you have vids of the dyno runs showing the hp.

Bro you should put a track on the back of that thing and do some ripping in the snow
That’s the plan lol I wanted to do that last year… But this year it might actually become reality😅
How much power would it make without the turbo ?
Probably close to high 60s or maybe even 70 with the work that I have done now
🔥
Hey boss who polished those cams? I'm looking to have a transmission, cams, crank all polished. Those look killer
CryoHeat. Tell them The street sweeper sent you. Ask for Josh
Tough bike though been following want to do my ktm but setting it for drag racing
Thanks! Yeah, the KTM is definitely a great platform for turbo forsure!
hey man awesome build I have a question does the exhaust side face the rear from the factory? and the intake to the front?
Yessir
How much it the ttl of ur build and how much horsepower are you working with rn
It was making 130hp last year on my old setup. I’ll have to tally it up, but it was really more labor-intensive than anything.
@@The_StreetSweeper thats crazy😂
Do you have full movement in the rear suspension ?
i see your point but with them tyres i dont think it's going off road? or is it, im new here.
@@aeroflopper He went off road before, tires can be changed pretty quick!
@@rfiskillingussoftly6568 he might have an issue then.
I still regularly off roaded it with this kit. I have a video on my page I posted last year.
drag strip in the near future?
Yessir!
Sheeeit
What’s your opinion on those corsa tires I’m running pilot power 2ct front and rear but I am needing new tires
No complaints at all! These are pretty amazing!
What is the clutch cover spacer for? More clutch plates because of increased power?
Nah, I still run the stock OEM clutch pack count. The reason for the billet clutch spacer is that I run a clutch lockout mechanism that operates off of centrifugal force. It’s pretty tunable because it has a lever arms that you can put bolts and nuts on to have different weights or basically different engagements of apply force.
can we expect to see it on a dyno?

Swap the yz turbo into a duc frame after that :D
Maybe one of those old small trellis frames 600 SS or similar
