[@LuxGamer16]

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 👏

[@jjhack3r]

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.

[@tejdz1337]

@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.

[@buggerlugz6753]

@@jjhack3r - Yep, WAY too rich!

[@martinandersson5278]

@@tejdz1337if the cylinders fire with 180dgr offset the result is what a tuned chamber does. You don’t seem to know the principle of the chamber

[@tejdz1337]

​@@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 ?

[@luketorpedo]

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!

[@patrosd2336]

the shaft in 2t is on bearings and they have play

[@user-cb2rq8iy9x]

Looks like it has a small one instead of 2 individual ones

Check out Allan Millyard's creations, a V12 Kawasaki engine in particular, all hand made in his backyard shed.

[@althejazzman]

Allen Millyard would be proud. He's the only other person I've seen saw a crankcase in half and not turn it into scrap!

[@terabeatnik2000]

then there's Le Dan, too

[@tommaguzzi1723]

I watch Le Dan. I also watch this guy who I suspect has aldo been watching Le Dan and has now upped his game.

[@princesssolace4337]

wonder how many crank case turn to scrap b4 getting it right

[@user-tu6fq1yd8i]

LeDan is the best

[@althejazzman]

@@tommaguzzi1723 I'll check out Le Dan but I think Allen is the OG here. He's been cutting up engines since the 90's.

[@trenenpierskalla5500]

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

[@mikeanderson2730]

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.

[@albertsammut433]

Excellent Engineering..with some more fine tuning that little mini should turn out lethal to ride👌👍

[@netroy]

did you mean lethal, or legal?

[@ubiquitoussterling6888]

Lol slow as hell😅

[@MrKongatthegates]

I do not believe I have seen anyone attempt to fabricate (and design/engineer?) an engine block by hand. Astounding.

[@contraband1543]

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 😂

[@awalcom5300]

don't forget le dan

[@ProlificInvention]

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

[@jamesferrell9404]

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

[@freddieparrydrums]

Own an AM6 RS50 (same engine) Stock with CP 19mm carb, got 68 out of her. Can push these past 20bhp

[@SUPRAMIKE18]

I went like 30 on a minibike and felt like I was running from the grim reaper lol

[@jamesgravel7755]

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

[@171apples171]

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

[@t0mateK]

this tinny engines can reach 20hp easy

[@smokefentanyl]

I agree, absolutely needs a gear box, imo incomplete without one.

[@leegraves101]

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.

[@Shadobanned4life]

Cold comfort,but you know something is good if someone steals it!

[@evilelf5967]

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.

[@ScarlettStunningSpace]

I didn't expect the bike to sound this good!

[@Kenno10rapid]

Top notch engineering skills. Definately deserves a new sub!!! 👏

[@ev0wizard]

This dude so talented, hope you have a high paying job with all these skills u own

[@Shadobanned4life]

WOW !🎉 Absolutely astonishing! Hat's off to a genius.🌞

[@BornAgain717]

Awesome work!

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 👍 👍

Damn, crazy man 😁

[@salvatoredrago8027]

you're really great, keep up the good work!

[@voodoo6936]

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.

[@Bruceai743]

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

[@warlock.420]

Please make a V-Twin for bicycle! You'd make the motorized bicycle community so happy!

[@davekauffman8727]

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!!

[@nestorgarcia2299]

Awesome skills!

[@erikbraguim4288]

Parabéns , que incrível projetos assim são muito bons , ótimo trabalho eu gostei demais , ficou massa !

[@Eduardo_Espinoza]

Superb work :D! I think the weakest link is the clutch not being able to put down the incredible power now, haha ;D!

[@kyleray4952]

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.

That's amazing to watch adding a second cylinder but I would think after cutting the block in half then bolting them together would need to be torqued to a certain inch or foot pounds but if it was I missed it.
