    Gpr 1200 nipped up on number one

    I have done about 11hrs on the ski now going realy hard and all good after replacing the rear crank seal and wreaking two rear cyclinder and pistons.
    Drive on the weekend going flat out after about an hour of rideing and now the front pison has nipped up very small damage but still needs replacing.
    What is weird is that on top of the piston are small mark like its been pinging Will they ping if they run to lean?
