Put a wot box on it
Nitrous or turbo?
Why not both?
Why not just put a bigger cheapo motor like from Harbor Freight? Twin cyl??
Should have added a wheelie bar for that kind of power.
That turbo works best on like a 500cc engine 500-600 should put one on proper bike like a cbr 600. Ghostrider had a similar setup. can actually make some really good power. That turbo will make 15 psi under the right conditions
Best donut quote of all time... "We're running out of un-dangerous spots"
new shirt idea!
Agreed

@Jack Wrath nah
I have not watched the video yet, waiting on 2 ads right now, but that better be James that said that it sounds like him 😂
I'm fully convinced this entire walmart motorcycle series was just one of Jeremiah's fever dreams that he just willed to fruition
Management: Fine...... We'll do a motorcycle series. But your budget is only $1,000.
Jeremiah: I can work with that...
😂😂 as a rider myself fuck it we'll take it
@@donjohn281 i always take this for granted man.
@@a-smith3y so did Throttle House gang.
... and I'm just glad to be alive to have seen it!
This is one of the best videos by Donut Media in months! Nice work, Beremiah Jurton. We can tell you put a lot of effort into it, and the results don't disappoint.
Hell yeah! Glad Jerry and the boys are getting to make some more motorcycle content!
The Engineer and The Mechanic are back at it againnn. Best duo on Donut
Which is which
The one with the engineering degree is the engineer. The one that does most of the mechanic stuff is the mechanic.
@@mikestander398 jerry is the engineer
@Alex Johnson winner of the most useless response in the first quarter of 2023 goes to you homie 👏
I mean Nolan and James are up there too
Jerry using this series of making a skuffed walmart bike a reason to buy a top of the range racing suit is the best grift I have ever seen. I'm here for it
I had the same thoughts... got himself sweet gear for "work"
I’m pretty sure they have like 10 nice racing suits lying around the garage at this point lol
Buy?! I’m sure it was a freebie.
I was slightly appalled at their lack of safety gear in previous episodes. You don't need to spend 10gs but it's 100% worth it. Even less expensive, but properly tested, safety gear is worth it's weight in gold.
Just an FYI - these little 200cc (stock lol) bikes are a blast. I have two Massimo bikes and they’re a hoot. It’s not about speed but big fat tires and little danger. Great in snow and mud ! (I also ride an Africa Twin and Wr250R)
The Africa Twin is a super nice enduro. 👍
Every day I regret selling my WRR
it's so weird to see you guys actually doing mechanic stuff for once. lol You should do more crazy projects like these, this is effectively the linus tech tips of over the top absurd cars.

I would absolutely watch a season of Hi-Low with bikes. Could even keep the costs down!
Hi-Low bikes should be, None other then SV650's. Massive aftermarket and even race series for them specifically - also pretty cheap to obtain.
@@_PSYDUCK_ would be too dangerous for testing
Next season of Hi-Low will be fwd jdm drag cars
@@justinroser6833 with some proper training (i.e California Superbike School) and the correct riders, it would mitigate risk. You couldn't completely remove that risk though. You would need a control rider too for accurate comparisons. You are right though, it would be inheritantly more dangerous.
@@math_pqn7755 Yuck, no thanks. No one wants to see FWD drag cars with skinny rears.
These two by far the best hosts. Actually knowledgeable mechanics. Bring back Tool Party also!
Agree. Miles above Carwow sadly.
@@purwantiallan5089 there’s so much above donut as well. But everything has its own flaws and tops
@@purwantiallan5089 carwow isn't a tinkering channel.
@@NVIDIAGeekify Exactly. Carwow is fantastic for its own reasons same as Donut is fantastic for this reason. I find myself frequently crossing between channels they're both very entertaining.
Garage54 is way cooler IMO
You should get more boost when you hook up the vacuum actuator. The turbo looks like it has VTG (variable turbine geometry). The actuator is connected to fins inside the exhaust side and activating that, the pitch of the fins will send more exhaust gases onto the wheel.
5:06 to skip the ads
Thanks
Y’all should have a set budget build battle between all the guys and take em around the track. the guys buy a 5k car and use 5k in parts and rate it in looks nd performance from drag races to track times, it’ll definitely show the guys personality thru the build and it can be an hour long ep showcasing there mechanic knowledge and ability !😁
That’s my take on a video idea but you guys can change the budget, and also for an extra bit , have a pro driver or a special guest come in drive all the cars and rate which one is the best street car
Bro someone just stole my comment nd idea
This would be awesome.
I don't watch hour long TH-cam videos. But I would with that premise.
@@BassFace1776 same here with their personality each person would be a segment of jokes and car building
I love eps where these two are the hosts. It really eminates experienced mechanics vibe with humor and fucking around.
Old school NASCAR!!! without the racism.
Hey... Let's get an Up to Speed episode on Wendell Scott and Wiley T. Ribs. Do it before February so it's not pandering.
If you already had it planned for January 16th I will allow it.
I wanna see a budget EFI conversion with megasquirt and some actually tuning for the turbo.
I have a couple of mini bikes including one just like yours. Get a cheap torque converter and it will do 40mph at least without the turbo or no2. Love this videos ❤
That mallet flip by Jobe at 1:42 is absolutely underrated
I mean, yes, but anyone who deals with hammers on a daily can do that on a whim.
Source: I used to build trusses, using a hammer all day. My hammer turned into a giant fidget spinner; spinning it around the head, 720° flipping along the handle, throwing it irresponsibly high and trying to catch it without hitting myself, using it as a baseball bat (and missing 90% of all projectiles), but most of all, double and triple flipping it over its long end.
Nearing the end of my time working there, I was pushing quad flips, but those were hard because I had to mix height with spin speed, both of which are intimidating and dangerous.
Cool stuff nonetheless
I thought you said mullet flip lol

These kind of videos where yall actually get into how parts work and show how truly frustrating the gear life can be are my favorite!
Brilliantly conceived and executed. Deserves an award
I'm surprised no one said it yet, but using nos as starting fluid was a brilliant idea that worked excellent. Awesome episode 🔥
Don't quite understand how that worked at all since nos isn't combustible.
@@brendan19841111 that's why he's a genius

Jerry was so awesome in this one, need more of this passively excited and joyous jerry concerned with safety
Woah!!! that turbo is bigger than the one on my Ford Transit Connect, 1.6 diesel!!! Just got it re mapped ,from 93 to a blistering 135HP!!
So fun! Thanks!!! Keep you the amazing creative work!!!
The creativity and know how to properly execute things in these projects is honestly dope to see , these boys really know what they doin
Honestly, the know how and experience these guys demonstrate is really underrated.
Except for the Subaru Hi-Low season.
@@Nanomusheens it would be arguable that the show is entertaining because they don't know what they're doing. Gives it the some dudes just trying to do something flair.
They must have watched Marty and Moog do it a few years ago....
@@lasskinn474 aaaactually ... i think they know all their mechanical principles down pat (see the bits about the oiling system, etc) and it's the goofy wrapping on the parcel that makes it *look* like they don't know what they're doing. That's the appeal for me anyway.
That fail montage! 🤣🤣🤣 So many memories. I'm so glad the two of you found your way to Donut!
which episode is the one they crash the car?
@@gtviper1158 one of the wrx videos
Anyone know which episode the screwdriver slapping Zach's stomach is from?
this entire video was either too funny to watch or too scary to watch 🤣 yet I couldn't look away 🙈 love it guys!!
probably the flywheel or clutch springs. you can buy different tension springs for speed and to remove governance. Also you could bore it out and drop a larger piston in there. That might be fun(ny).
James and Nolan are great, but Zach and Jeremiah are my favorite because they actually have so much knowledge when it comes to cars and a lot of the time they are the ones doing the hard work and I appreciate the fact they are good characters and also good mechanics
James and Nolan are good for D List and all the review stuff
Zach and Jere are good for mechanical work and B2B and just explaining cars in general
Personally I prefer them all together
Love Zach and Jerry but having Nolan and James just reminds everyone that we are all idiots at one point in time and have knowledgeable friends who are also always learning. It’s a good kic
The comedy of him riding in 12k worth of safety gear is amazing!
Anything to protect that beautiful face
lets be honest, it was a 50/50 shot of this crappy little bike killing him after all these mods lol
lol not even close to 12k. A full 1-piece Dainese leather racing suit (like he's wearing) is around $2500 on the extreme high end. All of his gear (boots, helmet, suit, gauntlets) probably totals around $4500
Edit: With a second look, the helmet looks like an AGV Pista GP RR - it was $1450 brand new, and you can get them for $1100 all day long. So maybe around $3500 for everything.
@@Hawk7886 fair enough I'm just going from what he said. I thought 10k sounded excessive tbh.
Nice job on listing the parts or where to get them guys. really appreciate it.
i know working with big team is hard and sometimes people are strange and things get a little bit uncomfortable.
but.....
these videos are wholesome, fun and interesting
it is a win
34 mph is actually impressive. That’s about as fast as my 49cc China scooter would go before mods. Given that this is a pit bike from Walmart, that’s pretty good. I’m actually amazed this thing hasn’t pinged itself to death yet given that I’m sure nothing has been changed on the ignition timing
Yet
We have some at our shop. There are performance tiered kits you can get. We got ours up to thirty. I would love to put. Turbo on them. Of course I haven't finished the video yet..
@@michaelmacdade6629 change the gearing, i have the same bike as donut and mine goes 45-50mph stage 1
With a torque converter it would have gone well over 50mph. That poor little clutch can’t handle it and the gearing runs out way too soon.
There are some compensatory measures they can and/or may have taken to help. Obviously, the engine is intended for 87 and I'm sure they put in higher octane. In addition, rejetting the carb for a richer mixture will cool the charge as it goes through the turbo and is forced to evaporate. With some sort of logic control, they could wire it to open the fuel solenoid (the one used w/ N2O) at WOT to inject extra fuel after the turbo to cool the charge further and reduce knock...
And then, of course, they could add an intercooler... but none of that is likely to be a big deal at the 2-3 PSI they are seeing.
Top speed was a nice improvement but I was more impressed w/ the increase in acceleration. Almost a 50% decrease in accel time is pretty amazing.
Turbos mainly give torque, the increase in power is secondary
@@licenciadoleopoldocanoloza1144 yeah
That gear is so awesome! You look straight up fresh buddy! 12:14
1:16 lmaoo bzz pooo bzzz pooo I'm excited to see how accurate he is on this sound because it seems like he's gonna be right

I understood that reference
I love how Jobe is just casually mig welding with no gloves, hes my spirit animal.
I was crying at 8:37 😭😭🤣
This is one of the best donut episodes ever
Would be cool to see supercharger, turbo and nitrous all working together in this little bike 👌
There will be no un dangerous spot left
im with this idea
Jerr can make it happen
I feel like for that they need a bigger bike!
It doesn't make any meaningful amount of boost because without volume in the plenum, you're working against the intake valve. The smaller the engine, and especially with single cylinders, the more plenum volume you need. Add about a coke-bottle sized air chamber in between the turbo and head, and increase the main jet size by about 50%, it will fly. Just make sure you design it so that the lowest part of the coldside piping is still the intake port, if that makes sense. You don't want fuel puddling up. -Doc
10:27 “that i mean…i love that”😂😂
This is why I watch your channel. Just look at the title and laugh. Then I watch the video and laugh more. Love you guys
"We're runnin' out of un-dangerous spots to put things" the truest words ever spoken on this channel
It's always fun to see when the advertisers don't let donut put their spin on the ads😭
That ad was longer than my life expectancy.
@@weirdbeardgarage yep. And that ad was from India and sometimes lasted 10mins.
@@weirdbeardgarage raid ads are always long as fuck
@@zuck4140and they only vary the script by like four words for each ad, brutal.
Get a stage 2 kit with a billet aluminum flywheel, camshaft, 22lb valve springs and billet connecting rod and take out the governor for goodness sakes, that's the one thing that's keeping you from getting good top speed and maybe even a smaller rear sprocket for the wheel for even more top speed. Probably add front brakes as well just in case lol.
Get rid of that clutch assembly and run a torque converter and you will run 45 on a stock motor. Lower rpms and more torque. Rides like a Polaris auto transmission atv. Love the content. Keep up the awesome videos.
"You ain't got nuthin but time!"
The look on his face hearing that just reminded me of every time I've had to sacrifice sleep in the garage. We all know that look. 😂
This thing goes 30 stock. I had this exact CT200U-EX and topped out at 30, and the way to do it, is to remove the throttle limiter screw on the throttle linkage. It limits like 30% of the bike's power. (I achieved 30mph after also partially disabling the governor, but aside from that, everything was 100% stock).
I’ve hit 45 miles with governor removed , header pipe and 40 tooth sprocket and I’m 280 pounds 😅
@rubengomez1589 Yeah the sprocket makes a HUGE difference! I was just about to run a new one that would've cut my ratio in half, and theoretically near doubled the speed. Unfortunately, I sold it because as a 15 year old, the police don't like when I ride it on the street and I wasn't looking to get my license at 18. I also never fully disabled the governor because I didn't want my valves to float, and didn't feel like spending 300 on a new flywheel, valve springs, and rod. These things rip if you know what to do with them!
Remove the governor and get a billet rod and billet flywheel so the stock one won’t explode past a certain rpm. And also putting a torque converter on or just straight chain helps by getting rid of the stock jack shaft setup
Donut had a great run. One of the best
I wish I could meet these guys some day, they seem fun as hell.
I say that thing needs a CVT/snowmobile style clutch on it, since yall cooked the one on it now. That and a surge tank for the turbo so it can build proper boost, similar to how BoostedBoi Kyle did on his turbo shopping go kart.
this uses a centrifugal clutch, but they do make torque converter kits for these to upgrade the transmission
Oh god, who is building after market parts for these?
@@lostalone9320 lots, its just a honda clone
@@kylemilford5968You have to check if it's a hemi or no-hemi engine, but yes
Wait why do you need the tank? This isn't a 2 stroke.... Oh it's cuz it is a single cylinder right?

@Jack Wrath typical bot
Wow!
A turbo on a bike and a super cool Donut bike suit!
I got a built 14hp 212 Hemi on my Stand Up Scooter that does 55mph and about to be hitting 60+ soon lol. Thing is pretty wicked. Doing bigger wheel upgrade now to hit 60+. Since I'm on 280/250 - 4 wheels. TINYYYY! 😅
I really hope you guys make more motorcycle builds in the future, I would be really interested in what bike components are worth upgrading and modifying!
10000% support this!!!
We need more bike content with these two bois making it happen. When it's them on the thumbnail ik it's gonna be banger of a video
We need the R3 to come back to the channel. That was by far one of my favorite donut episodes
This series is great!
Mountains move when these two team up. 🔥🔥🔥
I think this just proves that the Coleman bike is way tougher than it looks. To put up with modifications like this and keep running is impressive.
These colemans are incredibly tough. Mine makes about 18 horsepower and can hit 60 in just a few seconds
They are pretty simple structures, and that engine is such low performance that its not really pushing it even when you double the power. Consider that KTM makes a similar size 200cc that makes 26 HP stock, you realize these aren't exactly competing against stock small motorcycles even with a turbo and NOS.
14:15, it didn't last a day with those modifications. But if you left it stock I would give it a year and my 14yr old self would have that thing ragged. Been there done that.
@@jakegarrett8109 The bike uses incredibly thin tubing. It is marketed as a children’s toy. They are not sold as motorcycles at all, they are mini-bikes with a 196cc log-splitter engine. This bike is $799, KTM’s 200 is a real motorcycle and costs thousands of dollars. I don’t think it is fair to compare. I paid an additional 800 for Tillotson 225 racing motor with 18+ hp that will make you shit your pants. It is not legal or practical at all, but it is fun. In their videos, the turbo and nos do almost nothing as the gearing has not changed and they made no modifications to the internals of the engine. I would be surprised if their bike makes even 12hp. These Coleman’s have the potential to hit 60+ mph. KTM’s bike is also a full-size motorcycle, these are much smaller.
@@nicholasgascoyne3144 I'm aware the limitations, since they were doing drag testing I'd keep the gearing stock (or use a CVT from a go-cart, or I've also got a small torque converter which allows you to double your torque at takeoff but mine doesn't have electromagnetic torque locking capability so you'll lose top speed due to inefficiency not being able to lock it at speed).
My guess is they turned that 6-6.5 HP engine into MAYBE 10 HP (could be 12, but I'm with you its still very close to single digits), and that's kind of my point. Any motorcycle engine is going to make more, even my grandfather's 90cc did 70 mph stock with a full size adult.
Kids wreck these all the time though, and you don't want parents angry that a broken pipe jabbed into a kids leg, so its not that thin. Also my neighbor was about 200-230 pounds when he was 12 (he looked like an adult), and his little 96cc roughly minibike held up to him making little tiny ramps (which is a massive loading condition coming down without suspension), so the frame design is quite good for what it is (it could be better, but its actually not that bad). And with low power its not exactly twisting the engine out of its mounts.
I did a draw through carburetor setup on my sisters old SAAB V4, the way I solved the distance from throttle issue was I ran a diverter valve from those old ford vans that had 2 gas tanks. I ran the fuel pump to the diverter valve and then put one hose to the carb and one to the throttle body. when I hit the diverter on start-up it pumps fuel straight into the throttle body, it's essentially just a really strong choke haha, love these videos!!!!
Love those v4 engines, sound is so unique
Genius, pure genius! Nice!
i been at my dads for the weekend and i came home with the video i been waiting for love you guys:)

Aw yiss this is much more Donut level of car stuff
Would be cool to see you guys all buy the best old junk cars you can find and make a long ass trip. (Kinda top-gear style).
24 hours of lemon style, but instead it’s a cannonball run
Yessss more motorcycle content!
I have laughed, cried, felt sorry for people, with things I have seen on you tube.
But you guys are just a lot of laughs. What a way to go. I wish you well. Next you will be doing a Cannonball Run.
You're laghing so much that it's easy to forget how complex it was putting this thing on the bike. Great craftsmanship guys.
Good work guys.
Try putting a torque converter on it you may be able to harness more of the power. Made a massive difference on my 200cc drift trike.
Keep up the good work..
Great fun to watch!
I suspect the performance bottleneck on small aircooled engines is the cooling, as I've seen faster variants of a bike that mostly just added an oil cooling loop, so now it can rev higher or accept a larger throttle input without burning up.
jeremiah + jobe wrenching on vehicles = best donut videos
Those racing leathers are impeccable! The lightning really sets it off. Absolutely magnificent.
I’m 6’4 250# and the clutch kit made our Coleman pop wheelies.
Yall guys are awesome you made boost and mph and that motor have more speed!!!! Jet that carb out!!! 40 mph!!!!
Jobe should get his own series like he had before with the Miata. Miss that a lot! And he deserves it
I love these videos where donuts does these builds and tests. It just makes for some awesome unexpected moments.
I love the tow motor tipping over, lol just one 4x4 a day dose the trick.
Great content!
And the episode is significantly cheaper to make than the WRX Build.
You should look into getting a torque converter for it instead of a clutch
You guys would be blown away if you knew the after market scene for those mini bikes. I have one that ive put about a grand into and it will do 80mph. Same motor, very similar frame to your donut bike. Check out OMB Warehouse, Studz Racing, or NR Racing. Cheers!
I liked the protection gear lol, very nice
The thought that it even worked is amazing. That really took serious knowledge and skill.
Throwing a different cvt/torque converter on this setup would actually go a long way
that and a V twin Kohler and it would be fast
😂all the mods on that bike plus that badazz biker suit` looks like he could travel back to the future😂😭 you guys are hilarious😝
The piaggio NRG 50 has injektors. (never owned one myself but ive tested an NRG with an 80cc Derbi cyl and some Stage6 pipe. fun times. ) might be a source for injectors. love the vid
Change it to a blow thru set up, won't destroy the turbo seals and you will get more power. Add a boost circuit, a larger pipe section before the carb to help keep the turbo spooled up. Then combine the nitrous with the turbo 😁
The stock carb was never meant to work above atmospheric pressure, so the boost can actually fight the fuel from coming out properly. Need a way to increase fuel pressure proportional to the boost in order to do a blow through application. Simpler to do what they did
@@lvr1028 there are mods you can do to make it more efficient. For a little project like this, it's fine. If you're looking for tons of power then obviously fuel injection would be the way to go.
A custom grind the cam , carb en bigger exhaust tube wil help a lot
@@lvr1028 Its literally a BOX around the carb, with a hose going from that up to the fuel tank vent. Its not rocket science, it keeps it all the same equal pressure. Seems easier to do that than work with the extra pipe plumbing.
You guys are nothing short of amazing! This was a fun video beginning to end. Thanks for keeping things entertaining and informative!
Could have even upgraded the fuel needals and increased the size of the fuel line diameter to improve fuel delivery
Suzuki Alto is what that means. Those small turbos come on Kei cars from Japan. My little Suzuki Wagon R has one, F6A is the motor and the kei car class is limited to 660cc / 64hp
The complimation of jerry's engineer skills🤣🤣
I love these "Jerry and Jobe's engineering antics" videos.

Definitely need to throw a torque converter on there and see the gains it delivers
this is the absolute next mod they need to do. i can almost garuntee they will hit 60 mph on that thing with a torque converter.
