Rebuilding my first vespa (77 P200). Just opened the head. Cylinder walls look pretty good. Approx 11k on motor. The rings are stuck and the piston has a few nicks. To be clear,, I am a novice. Do I need another piston given the damage. As I understand it, a new piston would need to be matched to the cylinder.

Hello over there,
If i were you,i surely replace the piston with his rings ! When i see the prices,it would be a shame if you don't replace him....
Kind belgian regards,
Pascal.

Hello there,
if you are planning on re-boring (which is the only repair after a seizure), yes the piston will require replacement as will the rings, the piston will be an oversized one which you can ask a dealer about while he does the cylinder repair. Hope this helps.
