    Other Guide: Fixing the crank case defect in 800/1200 PV/1300 engines (bonus: 1200R/1300 timing curves)

    If you have an 800 PV, 1200 PV, 1300 PV or 1300 NPV. Congrats you have a manufacturing defect with your crankcase that requires fixing. All credit goes to Group K for discovering this and Harry Klemm for the writeup but, sharing here as unfortunately it’s not properly documented elsewhere...

    GP1300R timing curve

    Posting for a friend that’s having issues getting into the forums. Does know what the timing curve is on a GP1300R? Is it the same as a carbureteted 2 stroke engine say the gp1200r which ive been told is 15°-18°?
