Thread: Piston size

    Piston size

    Hey guys,
    I'm rebuilding my SL1050, and I'm not sure about the piston sizes that I have to order.
    The ones that were in the engine was ELKO pistons, and on top it says 80.85 on one, and 80.89 on another, and I can't see it on the last.
    The cylinders look okay, and I'm not sure if it needs a honing.

    But do I need to order STD size ? Or shall I take a 0,25 and get the cylinders done ?

    Best regards,
    Jesper from Denmark

    I would say you calipers are accurate to the 10th of a mm. Look like std bore.



    Might be able to do a light hone and re-ring
