1975 CB550 K1 Would you use this dinged piston or replace it?
« on: December 29, 2009, 10:28:08 AM »
I accidently dropped one of my pistons and put a nice ding in it yesterday (pics below).  I have 4 extra pistons from a 1977 parts engine that are dirty but in pretty good condition. 

Should I swap one out or is this ding inconsequential?

I would file or sand it so nothing is sticking out and no sharp edge is present to get hot but I think it is fine to use. Do a google search and see where the sealing really happens between the piston -rings and wall. This spot is never meant to touch the cylinder wall. Dan
