    What is the out side diameter of the wrist pin for the Seca 550?

    I thought I had one to measure but cant find them, off the top of my head I think they are 15mm because when I was going to do a big bore kit I was looking at CB650 Honda pistons and that's what they are

    Had a couple left over from an '82 550 Maxim.
    I just measured them and they are indeed 15mm .
