I just bought a 2000 Kx 250 off of a close friend and the bike is in excellent shape...has great compression and runs great. The problem is you have to bump start the bike because this is the 3rd time the kick start shaft broke due to kick back. My Friend said when he got the bike 2 yrs ago it kicked over fine. He put the bike away for the year and all of the sudden started having this problem. I should also probably mention this bike was piped and jetted by a reputible dealer in my area but like I said when this bike is running, it sounds and runs perfect. If anyone has any ideas as to where to start with this problem they'd be greatly appreciated....Thanks in advance
