This series spiraled into one of our biggest and sketchiest builds ever lol. If you’re into this please HIT THE LIKE BUTTON so the algorithm can let us do more stuff like it! We’ll be dropping the other 2 parts this week
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 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.
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!
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.
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.
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.
@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.
@@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. 😂
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!
@@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.
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
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.
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
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...
fyi those engines have a mechanical governor inside the crank case. It's a plastic gear with a spring clip on it. Remove it and cut down the shaft so it doesnt break off and you're good to go.
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.
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.
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 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.
Bro this is my first time catching your vids...you rock...you're getting to do all the things I used to dream about doing when I was younger...alot younger...God speed..
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?
JERRY! Now that I have your attention, I’m surprised you guys also didn’t do a billet block/bottom end, maybe a future modification, or did the part just not exist?
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.
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
I love Donut! Love this project. Just a note on this video. Some clips seemed a bit to color saturated. Blacks looking blue etc. Checked on multiple devices too. Just keep note! Unsure if others agree!
$160 in parts that little engine would get u to 80mph easily. My 196cc mini bike does 65 with only gov removed,40t sprocket,valve springs and carb/pipe My 420cc mini bike does 96mph with billet rod,50lb valve springs,twister cam,straight chain,37t sprocket,flywheel maybe have 2500 into the 420 engine
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
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.
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.
@@draimen3371 when the block of the wildcat is literally built with more rigidity than the tilly. Look at Redbeard's review of them. Thank me later. The Wildcat is the best built Honda clone as of 2024! Period!
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.
Bike made with sketchy materials rotating at 9000 RPM, above acceptable danger for the common folk, but bellow the danger of a home brew steam powered rocket. As an engineer, I give this 10/10.
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.
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.
Me watching Jerry assemble this engine with stock bore, stock cylinder head with stock ports, stock timing, stock crankshaft, and a giant carb-"That thing is never going to make 28hp. And it's probably going to run like ass." I haven't finished watching but yeah, it made even less power than the stock 3.5hp. Wow
Love your vids guys. I think the spark plugs reading is way off. Good plugs don't look black and sooty unless it is running rich or there is oil getting past the rings due to low compression. Also, no need for a fuel pump unless you are going turbo. You can gravity feed an early CBR900 for instance.
Throw a 30mm carb and install pulse correctly so you don't have oil spewing and congesting pump diaphragm. Add catch can. Run pulse after catch can so oil goes into can not into the pump.
My recommendation is to change the wheels to a thinner wheels and larger diameter and also find a custom exhaust muffler to put on it as well it can help you gain a little bit more power.

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.😅😂
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

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

Throw a 30mm carb and install pulse correctly so you don't have oil spewing and congesting pump diaphragm. Add catch can. Run pulse after catch can so oil goes into can not into the pump.
My recommendation is to change the wheels to a thinner wheels and larger diameter and also find a custom exhaust muffler to put on it as well it can help you gain a little bit more power.
