Will pay up to $100 for 50cc china motor

Question- why don't you just get a new piston and ring, plus an exhaust from them? May be a lot cheaper and faster in the long run.

OK, if he doesn't follow through I will try to buy from him. Being a bushing motor, won't it wear out faster?

Don't know, can't say. I have heard the bearing ebgines have problems, but that was awhile ago. No idea really.

I was just thinking something similar: new cylinder, piston, ring combo, and new gaskets, and new muffler. $60. just to be safe. So that would work? I couldn't have damaged the crank or anything?

 

[Bikeguy Joe]

Nah. You may want to look inside or clean it out a bit if you find broken or missing pieces when you take it apart, but you'll be fine with replacement parts.

OK thanks I think I'll do that if BGF fails me like his reputation says he will.
Any advice on putting the new parts on?

 

[Bikeguy Joe]

Take your time, clean everything well, and don't overtighten the nuts and bolts. Make sure you line the ring up on the piston with the ring alignment pin...you'll see it in the ring groove.

That is all.

Thanks for your help. I will let you know how it goes.

 

[Bikeguy Joe]

No problem.
