just got given a 79 cr250 motor only, bad thing is it nipped up 15 years ago and has been left open and has a slight amount of water enter the crank case,the bore looks like it might clean up with some 2000 wet n dry so can you still get piston/rings and a rod kit for these classics and has anyone got a rolling chassis or bits of a roller or will the motor go into a different make frame as ive got a yz250 h frame so i can go dirt tracking with it,any leads fellers?
