mid engine amc car

Do you have to rebuild a two stroke motorcycle every 1or 2 years?

I have a two stroke 1989 kawasaki kx80 and it runs . it hasn't had a rebuilt engine AND HAS ABOUT 100 HOURS. do you have to rebuild it that soon if it isn't raced. if it doesnt get rebuilt that soon will it destroy the cylinder allot faster? or does it


I have an '06 KX250 and I plan on replacing the top end this summer. I don't race either, but I do trail ride a lot (usually somewhere between 15-50 miles per weekend depending on what else I have going on). Like anything else it depends on how you use
