Hi, i was riding my kx250f the other day at a track and when i landed of a jump, my engine cut out. I tried starting it up again and the first kick was super hard, but then i was able to get it started, ride a couple of feet and it cut out again and the kick starter wasnt budging this time. Took it home, and when you bring the cams dead center, the piston moves fine and the kick starter kicks once and then locks up again. took the engine apart, top end was fine, the gears in the kick starter were fine, saw a little into the crank trough the top end and that seemed fine too. I dont know what to do from this point, if you guys can help me out itd be great. thanks.
