There is a good chance your carb fouled up while it sat during the rebuild and now it needs to be cleaned.
What exactly have you done since you started it? What do you mean it doesn't rev out. Does it rev up to a certain rpm, run kind of ratty, and smoke a lot? My bike does that until you get the pipe hot. It wont even rev high enough in neutral to get the power valve open, until the pipe gets hot.
its only been sitting a week. it feels like its not evan hitting the power band, i have a procirtui head pipe and it cracked so i welded it and i have no silencer yet. but it ran very well before the rebulid. do two strkoes take a while to break in or somting like a gas rc car. i rember on those it took a little bit before it let you go open throttle. now i haev to push it then jump on and put it in gear with out it stalling.
welll i dont have a manual i put the arrow on the piston facing the front wheels, once it starts to roll though its about the same. il give it wot it feels like im on a 50 goin nowhere. and yes it smokes
Well, with a powervalve stuck open, most bikes will feel pretty gutless. But, once you get some RPM built up, they really hit the power band and take off. Did you replace the spark plug? How do the reeds look?
