Mine decided to crack a piston. I have a 1998 wr400f. LOVe this bike, but don't know where to find this piston. Can't even find a sleeve. Mechanic says it need a 97mm piston with a 18mm pin. Any idea guys on where to find this? Everything else in motor looked stock to him. Is this a good idea anyway. Dont want to fix this so it can blow up 100hrs later. I bought this bike used a couple of years ago.

Thanks in advance!

Has anyone heard of putting a 97mm piston out of a 03-05 wr450f into a 98 wr400 motor? kind of thinking that is what is going on.
