why would it smoke though? i just rebuilt the entire top end with new cylinder, piston, and rings all... why would i put more new rings in? and yeah i know about the break in thing, let it run then cool for about 5-10 times like i would a blaster. and it is like buying a new dirtbike or fourwheeler, they come with "break-in oil" in them for a reason lol. i am running pro honda racing oil in it same as everything else i got. and are you saying that it smoking right now means it's always going to? because after i let it idle for a while it didn't smoke as much as when it first started and i thought it was starting to settle a little.
