When I was in college, there was a "little person" who lived in the apartment above me who had a pocket bike. Little homie would carry that thing down the stairs every morning and try to start it with the pull starter for a good 10 minutes every morning before driving it the three blocks to campus. Dude was my hero.
Interesting choice of words calling someone a ‘little person.’ Ever thought about how that reduces them to a size? ‘Person of short stature’ puts the person first-it’s a way to describe, not define. Just a thought if you want to level up your respect game!
@@NightNurseMike He was my neighbor, he preferred the term "little person." Different people in different areas prefer different things, and that's okay.
I know that turbos are cool and all that stuff, but two strokes are a completely different beast. If you want to make some real power, you need to get an expansion chamber on that thing.
@@Drosba A supercharger wouldn't work on this motor. You would have to redesign the whole engine. Force induction on a two-stroke would just be passing the air fuel mix straight out the exhaust and would run like garbage. Better off getting a new pipe and do some port work. That would easily triple the power the thing currently has.
@@ncopp4358 I know it's not possible but theoretically would a pro charger work really well? Like if this thing was fuel injected cause I know it's not really possible with a carburetor
You need the expansion chamber, 2 strokes work a whole lot different than 4 strokes. The expansion chamber is part of the engine functionality as it is tuned to create an optimal shock wave that helps with pulling the air-fuel ratio into the cylinder. 2 strokes are a whole beast in and out of itself and getting the exhaust tuned properly takes a lot of research and consideration
The exhaust doesnt pull the mix into the engine from the carb, it scavenges unburnt exhaust gasses back into the cylinder, the expansion can be made longer for more bottom end power or shorter for more top end power which changes the wave. Ideally to make a turbo work effectively on a 2 stroke you would need a timed rotary valve on the exhaust to allow the cylinder to have positive pressure and also still scavenge on the exhaust gasses.
@@capitaint9560 Oh yes it does, a well tuned pipe WILL pull extra from the transfers, but only with a reed intake because piston and rotary intakes block any extra feed when transfers are open. Been plenty of development in the past decades, even DI engines meeting latest emission demands(!) so we might be in for a bit of a 2-stroke revival in the near future... Awesome time to brush up on your 2-stroke knowledge✌
@@henkverzeijl1525 moreso the piston pushes the fuel mixture into and through the transfer ports, whilst having a reed block so still nothing extra from the carb. So my point still stands. I hope as well as you do that they make a revival but i'll hold my breath, theres been some great developments with EFI 2 strokes and if they can meet euro5 then i'm all for it!
@@capitaint9560 The piston indeed pushes when off the powerband, but a specifically port-matched pipe will pull extra vacuüm while transfers are opened, kind of supercharging the intake traject when piston pressure drops. All comes down to resonation associated with extremely high rpm's, so more with vibrations/ wavelengths than exact port timing. Look into Helmholtz resonators if you're interested, it's an entire rabbit's hole of its own👍
This was such a fun little project! If you want to build something like this I linked what we used in the comments! If you are stoked for the 3 wheeler first drive leave a like!
I've never shopped for a welder before and didn't realize u can get stuff that cheap now, felt like that was the kind of thing you had to put a couple grand towards for some reason. So does the welder u shared actually work alright on 110v? Or is it the kind of thing where it "technically" works, like barely, so they can advertise it like that lol and u actually need to have 220v?
@@koijoijoe from what Project Farms has shown it’s exactly that. They don’t accurately produce the amps that you set. I’m thinking about just going with a Lincoln Electric multi phase LE31MP.
@DustySteel oh I've GOT to start remembering Project Farm exists lmao couldn't be a better place to take my questions too to get answered lol thanks! Good luck on your welding journey and whichever one u choose!
I'm curious why you wouldn't have re-jetted the carb. Forced induction only works when you increase the fuel alongside the air (boost). If all you do is increase the air, you won't really see more horsepower unless it was running super rich to begin with, you just run the motor super lean. Unless you're dealing with a fuel injected motor with a MAP/O2 sensor, adding a turbo, supercharger or NOS without adding fuel is pointless. I think this mini bike would only be a bit faster because the factory ships these motors running crazy rich, which was pretty obvious given how much smoke it was producing out of the box.
It needs the carb putting inside a presurised plenum, otherwise no jet changes will be able to fix this. Blow-through carbs NEED a pressure reference from the turbo, and the easiest way to do with without making modifications to the carb itself, is to just put the carb inside a box, and pressurise the entire box with the turbo.
@@noxious89123it's not a blow through, it's a suck through carb, the carb needs to go before the turbo and hope the turbo doesn't spin the fuel out of the charge. Even then it still won't work
Born in the 90’s I grew up on pocket bikes til even past the age of 21! So much fun. Coming across this video of a pocket bikes randomly brought so much memories 👏🏻 🏍️
I used to have a mini-moto. That thing could beat road legal scooters. Ended up swapping it for a P-wee 90, semi automatic 3 geared yamaha that gave me a 6 week summer holiday that i will never forget....Fast forward 20 years and I've just bought my first road legal bike (HondaCBR). Always had a car but my god i forgot how fun riding was!!!
@tobywhatman8741 offset pin for higher top rpm, smaller rear sprocket for more top speed, performance air filter, lighter "valves" those 2 plates that move, forgot their name.. was gonna do a bigger spray nozzle & big bore kit too
A few yrs ago during lockdown i welded two of these together, made a mini twin engine drag bike, about 4. 5 ft long, with both exhausts one over the other, they shear the rear sprocket bolts tho as they're so tiny, i wish i could post a picture for you to see
Me and some friends bought a few of these when we were around 13 years old (20 years ago). One of them had the exhaust pipe touching the gas tank, which inevitably melted through and spilled gas everywhere on the first ride…lucky it didn’t catch on fire! The design of these things hasn’t changed at all since then…absolute death traps! Try adding an advanced timing key on the flywheel - made a surprising power improvement for such a cheap upgrade!
I used to race these types of mini motos ranging from these cheap Chinese air-cooled bikes to 5k for the watercooled euro bikes producing 15+HP. A good engine builder would get that bike going a lot faster and sound a ton better with just an upgraded clutch, pipe and carb.
I like how genuinely you say have a good day at the end… Now you guys need to start offering stuff like the nuts and bolts cleetus has, LTT screw drivers or the monster max sledge hammer I just bought. Interesting and or quality usable RUclips products are where it’s at.
I love the track suits. That's how I *always* ride my ZX10R. I'm in Utah... you should bring your bikes down next summer and we can go rip some canyons together.
Hi, a little hello from France 🇨🇵. I'm also building a pocket bike and I reached 56kmh (35 mph) but without turbo 😉. Thank you very much for this video, it was nice.
I’ve never ridden one of these but my brother bought one of the pocket quads about 15 years ago. Man we had fun ripping around on that little thing. Had a 49cc motor we modded a bit
It needs the carb putting inside a presurised plenum, otherwise no jet changes will be able to fix this. Blow-through carbs NEED a pressure reference from the turbo, and the easiest way to do with without making modifications to the carb itself, is to just put the carb inside a box, and pressurise the entire box with the turbo.
I remember when these were $199, my little brother had one and I had a 110cc “super bike” version with speedo/headlights(highbeam and low beam/taillights/signal/horn all decked out. Even though his was a 49cc it had a higher top speed than my 110cc which topped out at 35mph (tested) so assuming his 49cc hit about 40mph. (Probably 100lb rider at the time) loved ripping them through the neighborhood when we couldn’t ride our dirtbikes. Good times. That was probably 15 years ago
They both have their pluses. You or I could buy these parts and put this project together. Ethan is a mad scientist who builds stuff we could only ever dream of.
My mate had one in 2009. I couldn't get on with it, but his body shape he could propper wrap himself around it and control it. He got it to 40 mph. I got to 30 and it was scary AF

Rocking back and forward when trying to go fast is always good for more speed. If you had done that, for sure you have hit it. Also, if you add some "Got Boost" stickers, that might have put you over the edge too!
If you pull the cylinder off and you raise the roof of the exhaust about 1 mm. It's already a case read but you can put one of those primer 15 mm weed wacker carburetors pair that alone will double the speed nearly
I feel like this was a great learning experience. Regarding back pressure, you need to understand that the pressure wave is created by the expansion chamber in the exhaust pipe. Without the tuned expansion chamber, you are actually making less horse power than you could otherwise. And like another comment mentioned, you NEED to put a slightly larger jet in the carburetor to really benefitfrom more air, or you may just burn up that engine. Revisiting this build with that in mind, you could have torched the exhaust pipe and bent it to allow the turbo to be placed elsewhere allowing the expansion chamber to still be a functional benefit and still power the turbo for boost. Maybe next, you could try a belt driven supercharger that is run off the starter pulley. 😊

I love your channel so much. I've been watching you since you came to GHP and I'll keep watching. With that said, I would really like to see you take safety more seriously. Riding with a helmet and wearing safety glasses when needed are 2 really simple ways to keep living your best life. I understand that often times safety comes 3rd when doing this stuff, but I would like to keep you around for a while. I have taken a hard spill without a helmet (causing a concusion and requiring many stitches) and I have shot a piece of metal in my eye while grinding (had to have it surgically removed) and a lesson I had to learn the hard way is that your brain and eye balls aren't organs worth playing with. I'm really glad to see you wearing a helmet on these mini bikes and hope you keep it up in the future. Thanks for the content gentlemen, I know this stuff isn't easy to continually create. I wish you guys the best with youtube and I'll be here for the ride.
I had a tuned up one I bored out with good parts it did 85mph 🤣 double exhaust & k&n filter it took on scooters on the road was dangerous but fun, so low to the floor but rapid
I have one that actually goes about 55-60 mph. Same size as this one on the video, not the mid size pocket bikes with gears. It's not your typical Chinese pocket bike though. Very sketch but fun as hell.
Now I need to fire up my old Blata Elite's again. Front wheel leaves the ground when you hit powerband, and they're topping out between 37-45mph depending on which model (air vs liquid cooled)
in order to make a "blow through" system work you would need a fuel pump to pressurize the fuel system to a greater psi than the turbo is pushing, otherwise the "boost" will push the fuel back out of the carb. cool video though!
There's an easier way! It needs the carb putting inside a presurised plenum, otherwise no jet changes will be able to fix this. Blow-through carbs NEED a pressure reference from the turbo, and the easiest way to do with without making modifications to the carb itself, is to just put the carb inside a box, and pressurise the entire box with the turbo. The carb doesn't "know" it's seeing boost, and if you put the entire carb inside a pressurised box, then it's outside pressure reference will also be boost pressure. It'll just be like riding it at very low altitude with high outside pressure.

Revisiting this build with that in mind, you could have torched the exhaust pipe and bent it to allow the turbo to be placed elsewhere allowing the expansion chamber to still be a functional benefit and still power the turbo for boost.
Maybe next, you could try a belt driven supercharger that is run off the starter pulley. 😊
imo those tiny minimoto engines don't use the zaust expansion chamber
It needs the carb putting inside a presurised plenum, otherwise no jet changes will be able to fix this. Blow-through carbs NEED a pressure reference from the turbo, and the easiest way to do with without making modifications to the carb itself, is to just put the carb inside a box, and pressurise the entire box with the turbo.
I love your channel so much. I've been watching you since you came to GHP and I'll keep watching. With that said, I would really like to see you take safety more seriously. Riding with a helmet and wearing safety glasses when needed are 2 really simple ways to keep living your best life. I understand that often times safety comes 3rd when doing this stuff, but I would like to keep you around for a while. I have taken a hard spill without a helmet (causing a concusion and requiring many stitches) and I have shot a piece of metal in my eye while grinding (had to have it surgically removed) and a lesson I had to learn the hard way is that your brain and eye balls aren't organs worth playing with. I'm really glad to see you wearing a helmet on these mini bikes and hope you keep it up in the future. Thanks for the content gentlemen, I know this stuff isn't easy to continually create. I wish you guys the best with youtube and I'll be here for the ride.
Excellent video ❤
It looks like a baby triumph Daytona 🤘🏼
pocket bikes look so fun.
Super hilarious! The fact that any of this actually works for this little money is kind of wild
I had a tuned up one I bored out with good parts it did 85mph 🤣 double exhaust & k&n filter it took on scooters on the road was dangerous but fun, so low to the floor but rapid
I have one that actually goes about 55-60 mph. Same size as this one on the video, not the mid size pocket bikes with gears. It's not your typical Chinese pocket bike though. Very sketch but fun as hell.
Now I need to fire up my old Blata Elite's again. Front wheel leaves the ground when you hit powerband, and they're topping out between 37-45mph depending on which model (air vs liquid cooled)
I keep forgetting this is your channel, and every time I click one of these videos and see you im pleasantly surprised

You got a 👍 as soon as I saw how you opened the box😂
‼️SAFETY GLASSES GUYS‼️
in order to make a "blow through" system work you would need a fuel pump to pressurize the fuel system to a greater psi than the turbo is pushing, otherwise the "boost" will push the fuel back out of the carb. cool video though!
There's an easier way! It needs the carb putting inside a presurised plenum, otherwise no jet changes will be able to fix this. Blow-through carbs NEED a pressure reference from the turbo, and the easiest way to do with without making modifications to the carb itself, is to just put the carb inside a box, and pressurise the entire box with the turbo.
The carb doesn't "know" it's seeing boost, and if you put the entire carb inside a pressurised box, then it's outside pressure reference will also be boost pressure. It'll just be like riding it at very low altitude with high outside pressure.
Really dig this video. Hell yeah bro. 😊
Don’t forget to port and polish the intake. Or build a hydrogen generator to add onto system and retune carb for fuel savings.
