ok do you have details on the kit?
I could probably find a bike to put one of these on.
how fast does it go??
My kit is a 66cc engine. 50cc is the legal limit... SHHHHHHHH
It comes with the clutch assembly, chain, rear gear. All the parts needed, some that aren't needed, missing some that are needed, and has some inadequate parts... like plastic non-bearing chain tensioner...
If you are good at taking engines and cabs apart and fixing them/tuning them. If you are good at going to the hardware store and getting creative to make, say, an engine mount. This kit is for you. It is cheap ($120) and after some modding, it works pretty damn well.
Right now I have the 44 tooth rear gear, I can go around 30mph top speed. I haven't had it up that far yet because I'm still breaking the engine in. It has a bit of a hard time pulling up steep hills... unless you mod the exhaust
I'm planning on making some adapters and stuff so I can run it through the gears already on the bike. So that would greatly improve everything.
I'll keep updating as I do stuff. I just finished replacing all the gaskets in the carb, intake pipe, and exhaust. All the seals from China were crappy and leaking already... I just bought seal material from napa and cut my own seals.
