    I replaced my piston this weekend. I haven't run it yet as I am waiting for a few other odds and ends. However, I just noticed the piston that came out was a "B", and I know what is in there is an "A". Ring gap was fine when I measured it. Is the A/B difference going to be a problem? Its already in, so no returning it...

    The "A" piston is just a thousand or so smaller than a "B".

    It will be fine.

    Cool. I was planning on running it anyway since the ring gap checked out all right. BUT thought I would ask, just in case. Thanks!
