    I am pretty sure Insandiego Joe used to run the 800 cyl set up w/triples on his GPR.

    I know Forrest uses the 800 cylinders too, on his triple. But if you are
    boring the cylinder to 1300, remember you won't be able to open the
    exhaust width up as much because the rear transfer port extendeds
    toward the exhaust. So basically if you go hog wide on your width, you
    could actually hit your transfer area or not have much left. So that space is limited. On the
    good side, the exhaust is already raised 1 mm over the 1200 cylinder,
    so they would work pretty good just by bolting them on. So it really
    depends on how much porting you want to do on the cylinders. It would
    probably be a big concern if you ever decieded on going 1400cc in the
