hi
❤️🔥
hey man so I became amember but cant find the discord link whats up with that?
Aeeeee The Lil Red!!! That's my name!
Aeee Lil Red
Jerry actually risking his life for content, respect
i think he would do it just for fun tbh
Jerry actually making his voice do that for an ad
Jimmy has jumped off a building for content, yet I see no one respecting my boy 😤
He is the motorcycle guy after all
Nah stupid
Welcome to the world of small engine modification! DEFINITELY gonna need some aero, these things hit a wind wall around 70mph. Keep it rubber side down and between the ditches fellas!
I love your content carsandcameras!! + you guys are very funny
I've been commenting you guys! Ahh seeing your comment made my day!
Ike would have done 120 on it.
Y’all are the og’s ‼️
Do I smell a consultation collab? 😏
Can we please get more of the guys just working on their personal cars like the one with Nolan? I'd love to see what builds everyone would make if it was for their own car!
Realest comment
yeah, definitely would love seeing more like that.
I appreciate the explanations of what everything is for. I'm not a vehicle guy at all, but I do enjoy understanding the workings of things even if I'm not into working on them. This channel has been a lot of fun for me to watch.
Donut is hitting that 2000s Discovery channel Zeitgeist more and more with every video. More motorcycle content like this please.
seriously!
Way, WAY more MOTORCYCLE stuff please and thank you!!🎉🎉
Absolutely. They need to figure out how to expand
@@repentandbelieveinJesusChrist8 lol wut
More motorcycle videos! 👊🏻✊🏻👊🏻✊🏻 braaaap braaaaap
Jerry balancing the mini bike on a shop stool 6 feet away from a vehicle lift is such a relatable scenario - you have the right tool for the job, but you use something not at all designed to do what you need it to.
Hey now, let's be reasonable. That lift was six whole feet away...😂
He's just trying to provide more content for Real Mechanic Stuff next video about non compliance with OSHA...
the mistake is trying to reason, none of this fit within the range of reasonable.
Not only is it the wrong tool, the wrong tool is on wheels.😅😂
Phenomenal video! So happy you guys are making this series. Definitely the content I like to see. Don’t feel bad about stretching the videos out a bit. It seemed like there was a lot that had to be cut out so you could make the video shorter. I wish you guys could have a side video with extra content or behind the scenes or something.
My life is literally better because of you Nice job guys, once again thank you for your constant hardwork!
Jerry is far more dedicated to the risks involved than everyone else here. Props buddy. I’d be nervous to go past 6k RPMs.
FULL SPEED AHEAD! let's get to 10k!
Mini bikes are sketchy but not that bad I have the same one and mine redlines at 7k rpm making about 10hp shits fast but controable
a weedwacker does more then 6k and you hold that right next to your chest
@FootF-mt7pd agrees started riding dirtbike last summer, been riding a 125cc finally got the courage hop on the kawasaki 300 crazy how more stable I felt on that bike.
dudes a literal engineering graduate. yea he's a lot smarter than he portrays himself on screen.
Not gonna lie. Jerry seems like he would be the best friend to anyone.
You definitely need to mess with the gearing, id try out 15(clutch)/53(rear sprocket). Max porting and polishing the head does sooo much improvement in air flow too. Also port matching and scoring the whole intake manifold helps with atomization of fuel.
I love how Jeremiah's videos have a Jeremiah-vibe all throughout. That Valvoline segment with the Julie Andrews nod was friggin' amazing.
Just missing a “yo momma” joke thrown in every now and then.
I know right Donut > Mad Men! If I need to sell something I hiring them as my ad agency!
You just made me scroll back to the Valvoline ad segment.
I'm driving engagement on this comment because I think the Donut guys deserve more money from their Valvoline deal
Like Adam sandler
Jimmy has such little brother energy
you didnt have to fry his ass like that bro 😂
@@PlayboyKeon I know right!
Anything with jerry in it’s good. And it may not be a real bike but as someone who works on bikes I’m happy to see him work on bikes and appreciate at least somewhat showing us him working on it and building the engine
Loving this series. Keep it up yall
Jerry actually risking his life to prove someone wrong, respect
how is he? curious
@@melvindoo2396 It's a bike meant to do 20 and they are trying to push it to 100, with all the modifications and increase in fuel air and compression it's basically a grenade. When the dude said "you better not blow my foot off" it was a genuine concern. But to be fair most engines are grenades we have all accepted as part of our lives.
@martinc7561 i think you think engines are much weaker than you think. Theres a reason they upgrade multiple parts that dont directly give it horsepower, it overall strengthens the motor as well. Only time it becomes a grenade is when you push it past the upgraded parts spec. Once those upgrades are on, its no longer "meant" for 20 mph. Its meant for whatever horsepower the upgrades can handle within their specifications. Just like with a regular unmodded motor. Its not even close to a grenade because they're operating it under the new modification's specifications. 😂
It’s great that the editors are now leaning into the community’s love for how Jerry pronounces the word “OARLL”
I laughed very hard at this, the way he says oil always gets me
Must be inspired by Rick Grimes "HEY CORL!!!"
He said stinky OARLL 😂
He did great on the Ad!
Loved seeing the breakdown and assembly, with Jerry's hilarious commentary.
Glad to see you guys putting important info out there about the dangers of stock parts. So many people just run them de-governed and blow them apart.
"It's not called faith... it's called smart" Great content BTW, looking forward to the next parts.
It's called...uh...uh...SMART
The only issue with that is we can see the MAC toolbox he has outside. A smart man doesn't buy tool truck brands, they get the part numbers off the truck, then look for whatever the parent company out of Taiwan is
A smart _and_ *lucky* man would use made in USA vintage tools
I would love to see a low bike and high bike series like for 150cc for 300cc or for 600cc. I feel like smaller cc would be much more fun
Low bike would be too dangerous 😂😂😂
Man that's such a good idea. A high / low series for motorbikes. That would be awesome!
Honestly a low and a high Grom would be the best thing to happen on this channel.
Greatest idea ever!
That's a great idea
This is exactly the kind of mad doctor shit I want to see when I open KZhead! Looking forward to the next 2 parts 🤘
Back in ‘95 (16yrs old) I worked in an alternator/starter reman shop. Another shop down the way brought a go-cart by and would do laps in our side lot. My boss/uncle got out his mini bike and they would race. It finally evolved to them putting nitrous on the mini bike and go-cart. The mini bike was scary once the bottle started to empty you’ld have to lean forward to keep the front end down. Good times, you’re bringing back good memories.
Whoever came up with the Tim Robinson edit deserves a raise, I spat out my milk when that came outta nowhere 😭
Donut is the only channel where I hope there is a sponsor. 😂 no one does ads or content like these guys
They’re just really smart tbh
That's what ya get when a professional ad house starts a YT channel
This feels like old Donut. Love it!
3 to 18hp was an insanely good gain for such a small engine, with just swapped internals and a better carb. Well done. I honestly thought that little pewee grade engine would have been tapped by 12hp, and needed nitro or likely not feasible FI to go further.
I wish they would have said what cc/size engine they're using. 3.4 hp sounds like a 79 or 100-ish cc engine. Those Phatmoto bikes use a 79cc but have cheap clutch & some other cheap parts. With a better gopowersports clutch & few others parts one of those Phatmotos could be very reliable.
Even though this is a sketchy series for you all to film (thank you everyone on the team for taking some risk!!), this is the first time in a while I’ve been REALLY excited for donut content to come out! Reminds me of the good ole days!
Those days never went anywhere...
@@cenciende9401 Wish unboxing videos... blah
@@cenciende9401 as much as I want to agree with you, I just can’t. The content has slowly changed over the years and it’s not bad but I don’t look forward to it. Opening Wish content is not the same as up to speed. Regardless, I will always watch and enjoy Donut media.
i love how these are filmed like those car tv shows but aren't as long or filled with all the boring stuff. good content, crazy i only just recently found this channel when it has almost 8m subs...
I'm *almost* jealous that you're just now finding it. You have a massive back-log of awesome content to catch up on! :)
I’m in the same boat just recently got onto this stuff
Dude, you literally need to get Up To Speed!
glad to see Jerry dropping in more two-wheeled contents on Donut
These Jerry minibike episodes are so good. I hope they keep making more in this series.
as a motorcycle guy who used to play with minibikes, I thought I wouldn't care for this content as I had been through it all already. I was surprised though, Jeremy can really make the episode and the smile when he adjusted his ignition gap and got the bike to rev out had me smiling at home. Great content guys as always.
Please keep at it with the motorcycle content, it's awesome!
Awesome, fun content! This video has a real grassroots feel that reminds me why I love motorsports
Mickey is one of the best dudes I have ever worked with in the industry. He was one of the only people our shop worked with that I looked forward to coming in to pick up parts or to go get parts from. Great man with a great shop.
Seems like a miserable old man
Honestly more surprised there are so many 'high performance' replacement parts for that specific engine.
The aftermarket is huge for these little engines. I’ve seen some making 30HP and they haul on light mini bikes and go karts. Fun and easy to work on too.
Predator 212's have about as much aftermarket support as ls engines
Fr the whole time I was thinking who tf out there making billet parts for this 😂
Oh gosh there's a huge aftermarket for small engines. Their parts are really cheap to produce and relatively easy. A lot of the world uses the hell out of small engines for bikes, just not the US cuz we're too SUV/Truck focused. A lot of asia, africa, and parts of Russia use a ton of small engines to get around.
Mickey sounds like he knows everything about anything he hasn't done.
Yeah not a big fan of Mickey. Imagine shitting on things for no reason, and then being an obstacle when they actually try. Why? What do you have to gain?
@@smooshfanultra it’s just a side effect of being a pessimist. I doubt he seriously wants them to fail he just can’t see things in an optimistic light
I think he is there for theatrical reasons, to be the voice of doubt that they need to prove wrong
I actually worked for him. He's extremely knowledgeable and knows what he's talking about. Terrible teacher but all around good guy
@@anthonybalmoja1800 this time he didn't, and how is someone so pessimistic an all around good guy 🤣
Even though you didn't reach 100 mph i had fun watching donut family's effort specially my man jerimiah 🤘😎🔥💯
Absolutely love these motorcycle videos! 🏍
Feels illegal to be this early
Welcome to the club
Lmao agreed
Same
right?
It doesn’t even say it’s on their page yet
In love with these crazy sketchy builds, and I feel that donut has the perfect hosts to do it
Drag-bike tip for going fast (at the cost of longevity) -- pull all the o-rings out of your drive chain, and run it on the thinnest gear oil you can get. The chain won't last long, but on a small engine you'll get a noticeable improvement in speed.
I’m hyped for this lil series.
you are supposed to use valve grinding compound on the new flywheel to make sure it evenly spins on the surface, and grind down any little pours
As he said, he probably just wants to get it to 100 miles an hour then throw it in the trash. He doesn't seem to have any particular love for the vehicle.
Im interested in finding out just how much was spent on this, im gonna guess way more than it wouldve been to just put a bigger motor in
"you sure about that???" 🤣🤣
If ads are like this, ill definitely watch it 🤣🤣
Jerry: “No faith?” Mickey: “Oh, I have faith in you but this isn’t a junkyard, this is a garage.”
I understood that reference.
It'll run on hopes & dreams.
I'm pumped for the next two parts!!
Need more builds like these🔥😌
Definitely one of my favorite series!!!
I had absolutely no idea there was a market for performance parts for small gas engines like that. So cool. Honestly, this is so much fun to watch. It would be super scary to drive it. I hope Jerry is wearing a helmet and pads for the 100 MPH attempt.
If there's no go fast parts for your engine you can have those custom made. Well known names like Wiseco, CP-Carrillo, Ferrea, SCAT, Crower etc. can do that for you, but you will be responsible for correct measurements and strength goals. Would be nice for the riding position changed to something similar to Top Fuel Motorcycle
Massive aftermarket for these small engines. You can build to mild to absolute beast running alcohol, E-85, and a ton of other fuels. Seen a few on nitrous as well.
Jerry's got that MotoGP airbag suit from a few months ago.
@@dellstudio10 I bet they go for nitrous here to callback to the other walmart mini bike
Those motors usually have oil level sensors near the on switch that cut the engine if it thinks it’s too low and when you mod it to do higher rpm’s it’ll splash the oil around a lot and the sensor will cut off ignition thinking there’s no oil in it
Great series idea. Keep up the good work
You guys are awesome and nuts! Perfect combo!
while i watch every video Donut puts out, i click a little faster when it’s a Jerry video. can’t wait for the rest of the series!
This is a great series. Hi-Low with mini bikes perhaps?!?
This is going to be amazing. I cannot wait for more!
70 on a mini is already crazy 😳 my mini does 55 and I'm not making it any faster intil I get brake upgrades 😂 love the video tho 👍🏻 I've been hoping you guys would do a full mini build sense before the first minibike video
Never thought i would see this thing running after the crash test. The little thing looked like it was totaled. Lots of respect to you guys, especially jerry for risking it all ❤❤.
Put a tiny turbo on it!
Hairdryer?
Oh hell yeah! I cannot wait for the other videos!
Dude yes. I feel like those tires need taken care of lol. Definitely meant for... grip. More motorcycle stuff is always fun tho.
Pretty sure on the last dyno they had slicks on, but it’s real sunny where I’m watching so can’t see that well 😂
@@whitford0 You're right, they had different tires installed for the last dyno attempt.
Jerry is the best. More Jerry vids!!!!
Loving the motorcycle content! Keep it coming! Merch next!
Can't wait for part 2 and 3 🙌
When they said Donut was going to do motorcycle content I wasn't expecting this. Gotta say, it's fantastic though
Pretty cool! You need to put a smaller sprocket on it if you want to try and hit 100 mph.
And taller tires.
14:34 *V-TEC noises*
Jerry working on bikes is my new favorite content
Madness boys, well done; i eagerly await parts 2 and 3! 😆
Every Donut video is informative like always, I love it!
Just want to say I love you to the editor for putting in the howie scream @14:05
When I raced gokarts, we had an open rules I raced. Only rule was the base engine had to be a Briggs 6.5hp overhead valve. We had a builder do a bunch of work and made about 40hp. Even machined in valves out of a Honda Civic. Huge carb with a triple stack pump. We ran on 110 octane gas. We tried methanol to make more power but the extra fuel needed kept washing out the rings so we went back to gas.
Been hoping for more motorcycle content here! Great job guys! On another topic, have you ever considered an “Up To Speed” on Local Motors?
I’m not even a motorcycle guy but jerry makes it look so fun. What a beast 🤣
I tried the Valvoline Synthetic High milege 0w20 oil, and my engine ran like brand new! It was quite smooth, and my fuel milage went up just like the car when it was new. Same using Valvoline gear oil in my differentials in my Subaru. I'm never going back to Penzoil or Mobile 1 or Royal Purple. The reviews say Valvoline has no review tests. I wonder why? I used to work on small engines when I was a teenager back in the 1980's. This video is cool.
I love how the dyno tech is arguing with a near budget-unlimited mechanical engineer, like he knows anything the other guy can't just calculate
Being a part of the bike community it makes me SO happy to see donut coming out with more bike content, keep it up guys!!!
So stoked to see the walmart minibike again! Such a fun set of videos.
Jerry's that friend who will save you in a pinch, and risk it for the biscuit in the same day.
Hell yeah!! So excited to see where it ends up 😍
awesome series, love it guys :)
You guys are the life and soul of automotive youtube.
Bro, your guyses videos are dank. Was hoping to get a request in for the next up to speed. Talk to me about Bradley kit cars. It was my first car, and people don't know about these things.
7:17 The biggest flex was putting some crazy expensive 1.3 ratio roller rockers in that head and not even mentioning it
Damn feels weird watching the video litteraly 3 minutes after posting. Keep up the godly content Donut.
You guys need to make more .oto content it absolutely slaps bro.
most fun i've had in a summer was tackling a predator build in a minibike! Topped out around 61 on a mini moto (even smaller than these)
Jerry has reached mad scientist level of cool! Like Doc Brown!
I would never think that I would ever see a Full bolt on mini bike
I usually have zero interest in mini bikes, but damn this was a fun one to watch guys.
This is awesome timing. I just bought a 1999 Prowler Jr. Shriner’s car with a 5hp Tecumseh that I’m going to attempt to build
Imagine how fast it could be if real mechanics were able to work on it. That’s crazy
This is the quality Donut content I sub for. Keep it up my guys.
I love these motorcycle content! ❤
Same its right up my alley
Dude you're a wizard and make more videos.
Wow so cool doing the same thing as alot of other KZheadrs donut is so original
I think Walmart sales of this bike has probably gone through the roof after these videos... I've been recently seeing people ride these all over the streets and trails here.
