riding today and motor seized i took the side cover off and turned the main bolt and the motor spun it was hard to spin at first but got easier after a while do you think its the piston ao the crank bearings??

 

when my lt250 first blew up,it was because oof overheating and the piston expanded,it locked up,then after a few minutes it ran again-but very crappily. There is really no way of telling what happend until you tear her down,could have lost a ring or something
