ok here goes, I have a 1998 KX 250 that does not kick start. once I bump start the bike it runs fine and will kick start for the rest of the day. When it is bump started it starts very fast, like on the first revolution.
I have the top end off and found very light scoring on the intake side of the piston, weak rings (end gap .035), a stuck open power valve and a nasty looking cylinder.
The cylinder is not scored at all but the coating is almost completly worn off. It seams very thin.
The power valve was stuck open because the valves areso gummed up with nasty looking black goo that it broke the snap ring off the little wheel on the shaft.
So here are my plans (please feel free to add anything else you think I should do). Anew top end, bore and re-coat the cylinder, Remove and clean out the power valves and repair the broken snap ring.
So after all that do you think I will still have a starting problem?
Thanks for all the help!
