Thread: big bore 800

    big bore 800

    what can be done to the 800s for bore increase?
    have been kicking the idea around of 1300 cylinders and pistons.
    OR can 800 cylinders be overbored and replated to accept 1300 pistons?

    If I use 1300 pistons can I use powervalves from them so I dont have to machine?
