1991 kdx piston problem

Post by sooty_250 »

Hi there new to all this . I have a 1991 water cooled kdx 250 it great fun on the muddy stuff till you ride it in to a pond . Now I have a problem finding a piston to fit my bore that is 67.3 and my old piston is a 66.9 . I can't seem to find a kdx piston of that size . Any help would be great thanks

Any markings on this piston? I think wiseco only went to 68.5mm. Has the cylinder been sleeved?

*edit* must have read that wrong. I thought you'd measured 69.x on the piston. Stock bore is 67.4, yes? So that would mean you are looking for a standard piston. Still, see if you can find any marking on the top of the old piston, that will help.
