I'm in the process of rebuilding my 1987 250x and I cant find a crank anywhere,does anyone know where to get one

 

will a 300ex crank work?

 

U can put a 300ex crank in a 250x bottom end. but than u have to use the 300ex top end. they dont make aftermarket cranks for the 250x as far as i know. If u need one i think i have one i can sell. Ill have to look.
