    are you boring the cylinders out for bigger pistons or keeping the stock bore?

    More info? im running a superstock motor with ported case and cylinders. Im using pro-x kawi flat top pistins with riva heads that have 33cc domes. What is your bore? 1300 or 1200? Oem? What head? Oem? I like pro-x in any install really. Post up what your building and youll get some great opinions thrown at you!

    Wiseco bought Pro-X a year or so ago. Wiseco has been maintaining the Pro-X brand / cast pistons.
