Seeing that this is a 2 stroke, i think an expansionchamber for each cylinder would greatly improve performance and rpm limit on this pocket rocket. Awesome build 👏
It's running rich. Some snowmobile engines use one expansion chamber for 2 cylinders all the time and the loss isn't too bad. His expansion chamber may not be optimal for that engine tho.
@jjhack3r it would work if he had both pistons firing at the same time, how he has them 180 degrees apart means pulses from 1 cylinder will work against the other and vice versa. effectively making the pipe act half as short, throwing the resonance way out of wack.
@@martinandersson5278 sounds to me like youre the one who doesnt seem to understand the function of an expansion chamber, and i dont understand what ur even trying to say? he put an expansion chamber for a single cylinder engine, ofc if it gets twice as many pulses per revolution it wont work the same right ?
Being precise enough in your work to weld together two crankcases and two crankshafts, and get away without needing boring of the crankcase for alignment is mighty impressive. Nice one!
Absolutely the finest art of knowledge, to build (or rebuild) an engine. When you look at a video like this, it looks decivingly simpel to to do something like this. But dont be mislead, only a few hundreds of a millimeter wrong messurement, or a few degrees wrong on ignition and the engine would be useless. You, Sir, are a true professional.
Cutting and welding two crankcases and two crankshafts together is impressive in itself let alone with a little help with a lathe and press not having to bore the case, using a rod the same diameter as the crankshaft to perfectly align the crankcase’s while welding was genius
Your skills are unmatched by 99% of small engine builders. You did in one video what would take me a year to accomplish. But you crossthreaded the shit out of that first intake bolt 😂
Very cool project, interesting build. I have a 2004 MotorHispania RX50, thing is considered a 9/10 scale crotch rocket. It has a 50cc liquid cooled engine that turns 15krpm and supposedly makes 7hp. It has 6 gears and a clutch. It won't do a wheelie easily but it does take me (250lbs) up to a max speed of 71mph, downhill, with the wind at my back. Regular riding I never usually go over 55mph
71 on one of these is insane. How it kept from getting the death wobble is beyond me. I ridden I think about 35 mph or so but would be scared to go beyond that
Very nice build. Reminds me of a Yamaha YSR50 that I put together with a 200 cc CS5 engine. Cleaned up the ports and made some expansion chambers. When I was jetting the carbs and getting the gearing right it would carry my 240 pounds at 85 mph. It was stolen before I finished it.
That was badass. These are impressive little engines. 4.75hp and it fits in the palm of your hand. I think your engine deserves a gearbox of some sort and a top speed run. Im also curious how well the pull start survives, pulling over 2 cylinders
Casually welding aluminium without any breathing gear or covering up your skin is a great way to shorten your life, lung cancer and skin cancer is a real killer. I used to tack stuff all the time without putting gloves on to save time, or i wouldnt connect my air line to my mask because the job i was doing would only take 30 seconds. But then i see the older guys who are in their 50s and 60s dieing from lung cancer and skin cancer, people who i know personally, so now i make sure i do it every time, no matter how small the job is. Even if it's not aluminium, cast iron or regular steel is still bad, especially if the metal has had oil on it at some point, the smoke will cause cancer. I also notice you handle a lot of solvents without using gloves which is another sure fire way to get all manner of different cancers and central nervous system damage, especially some of those older part cleaners that im almost certain aren't yet banned in the country you are in. Tetrachloroethylene is one of the worst chemicals you can put your hands into, and what's worse is that your body cannot get rid of it once it's inside of you. You really should consider wearing some protection, gloves are not expensive and if you can't get nice mask with an airline and air filter pack at the very least weld outside with a fan set just above your arc. And for the love of god check your solvents especially for Tetrachloroethylene, there are lots of alternatives out there which aren't quite as dangerous. Or you could just wear gloves!! I love your videos but someone has to tell you this, stay safe.
Just don't worry about people like this guy, is probably put by some company just to try to make you nervous you keep doing what you doing and so far you are on top in my book
Dude. That was sick. You’re a beast and you made it look easy in the video but only a few people will fully appreciate how much work that actually was. That’s sick. A lil tuning the carbs and I bet that thing is a beast
Bro , you've given this generation and generations before it who've never thought about doing something like what you did . It's amazing what you just did and it pays to have all the necessary equipment to do what you did . Thank you it's an epic video 💯
Well, I'm blown away by this gentleman's creativity. This isn't his 1st build. I enjoy watching how things are made in other foreign countries around the world. Apparently, you dont need a state of the art work shop. The editing skills are just as sweet. Nice work 👍 👍
This is by far the best build video out there hands down..! I am sure this project was nowhere near as simple as your precise editing has allowed us all to enjoy your talented skills and abilities to think outside the box and create such an idea so masterfully.. your talents i am guessing really have no limits and i am now curiously wondering what you might create next.. good luck and good blessings to you and those who support you.
Great work as ever,definately needs a decent expansion chamber exhaust you can hear it choking as the revs build up.asides from that it looks a hoot to blast about on.
Cool project. Amazed it ran. Drastically increases the torque of those cag engines but unless you change the gearing or increase the rpms you won't gain any speed compared to stock. An easier project is to fit a bzm to it. You would triple the power compared to the motor that you just created.
Your machining skills are very impressive, I don't know if I could be as precise when flycutting a surface that flat, only taking off .005" or the metric equivalent, whatever system you're used to. The union of the two crankshafts was also amazing, though I might have used a more solid joining than press fitting them. Incredible!!
In addition to the shock that the creative work brings to me, one detail that touches me is that he darkened the strong light during welding to make it less dazzling. This is actually very important. In some other people's videos, These bright lights make the audience very uncomfortable and quite dazzling

So sick!!! I'd love to see you make an Inline-4 with four of those/some 50cc bike engines sewn together. Then run it longitudinally with a driveshaft to a diff/transfer case in the back. Maybe make a pocket quad/mini 4-wheeler that way. That pokemon (pocket monster) sounds awesome as well!
👏 Excellent engineering.. you are very good at 2 stroke engines, I think it is very powerful. With some more sophisticated adjustments, this tiny mini car would be dangerous to drive👌👍
Needs an expansion pipe, if you added a small tail pipe off the fat can it may build the pressure you seek,,,,,,this is Dan ,,,,,,think,,,,Dan you are the man 🙏
Now! Put a regular CVT on that. so it can show its full power! 🎉😊 i love your works! i am always watching your video! From Philippines! 🫰😁 P.S. I also want to see a four cylinder pocket bike! i would love it! 🤩😊

Очень круто получилось Но вопрос, не помрет ли сцепление? Ведь момент увеличился в два раза почти. Думаю, можно смело ставить коробку передач и на большую раму)
Ottimo lavoro manuale, ma come pensi che funzioni bene avendo le fasi alternate di 180gradi tra i due cilindri in un unica espansione?il 2 tempi deve avere contropressione nello scarico, quando la camera di combustione si riempie di miscela, come li hai messi devono avere per forza 2 espansioni, anche la fumosità dimostra il fatto che molta benzina non venga bruciata...
Ok bro, i have a challenge for you. Find a heavy equipment fuel pump. Something off of an old Detroit or caterpillar. I mean, an old alfa Romero spider had a similar setup to what im suggesting but those are more rarw. Anyway, those mechanical pumps, like a lot of pumps, are like miniature engine. Cool thing about the old cat ones is a lot of them are inline 4 cylinders and are exceptionally well designed and made. The rotating assembly might even have the strength to handle boost....you see where im going with this? I know you can get it done, lets see how good you are. Build an engine out of a mechanical fuel pump that doesn't just idle. But will pull rpm and hold up to at least 8 psi of boost. Id suggest running it on pure methanol if youre gonna push it hard. Keeping it cool is gonna be a huge part in the reliability and methanol brings intake air temps down enough to create cold condensation on the intake manifold.
