I built a 29" beach cruiser, 80cc petrol engine. Shaved the piston took out the baffle put a 36 tooth sprocket on it. Got 42mph. Heavy ass bike too, plus im 175lbs. Had a lot of fun with it 😂🤘

I have this exact same pipe too, very loud but the torque increase is substantial

Got my bullet train electric start completely rebuilt with a billit machined liquid cooled head forged pistons crank and Conrod were already pretty strong double spark plug ports 2 stroke EFI & a smart carb water pumps are electric too so no power lose as if it were a crank driven pump & alternator already uses crank power amazon exhaust with expansion chamber and a welder shop did all the measurements for chains and gears to gear the engine to the crank peddles cut the peddles and cranks off so its balanced & just a gear welded a stationed gear from the engine to the crank and was able to use a regular bike chain from there with a mountain bike 6 or 7 speed transmission ran on ethanol with 2 stroke oil never could dyno it but it blew up the CVT clutch after a burnout drove it but was scared to reach top speed but id say i hit probably almost 90 mph and was 70% throttle at like 6, 800 rpm running at like 190 degrees after a warmup id say maybe making like 15/20 hp had a cheap engine temperature tack and rpm reader you can get for like $15 or less on Amazon its pretty accurate just gotta wrap a wire around a spark plug and go into the settings and set it for 2 stroke engine

I have this exhaust but its very loud so i welded muffler and its so much better

Add another 12 inch length to the tip of the muffler get all the power bands out of it that's the reason why it come short they don't want you touching full power

[damnthiccassboye]

how do you get such smooth idle, mine is kinda weird idk i have a vid + amazing job you did to the engine

[TimNiro]

That's all I need to hear to buy one for my bike 😂

[chevysilverado]

I like it but would that burn your leg

[sasquatch_]

Put a muffler on the end of that exhaust bro gah damn

[tideofamoleculeweonceknew]

Yeah yeah but at least his right foot will get a massage on the pedal rod.

[tylerrathe]

Run your fuel line and clutch line inside those two bars in your frame so you don’t have to have your pipe all the way out there

[billrivers]

Nice Bike you have what’s your top speed with this set up????!

[smartdummy]

if you can put the buffer in the back this would be legend

[quintonross]

What mods did you do to grt it sounding this good? Did you also balance the crank?

[RaoulDuke]

Hey is that a huffy Cranbrook cruiser bike?! I got the same one minus the engine 🤣😂

[Thehondacrfkid]

Yo, I’m looking to put an engine in a bike like this if this is a perfect working engine and you recommend it, can you tell me the name of it, and where I can buy it?

[joseolmedobuitragocastano]

Lo que más me gusta es el tubo de escape.

[Tiles-]
