    it is not easy to do - the FZR driveshaft is a different diameter and the inner diameter of the FZR pump is a different diameter - this means the bearings on a FZR pump are a different size

    are we talking about a gp pump?
    a gpr pump?
    or a gpr/HO pump?
    i was under the impression that a gpr/ho pump can be used on a sho/fzr. you just need the bearing for the thicker driveline!

    you are correct.
    i tried to fit the oem pumpcone on a gpr/ho stator and it is not even close.
    it looks like i have the core for a skat magnum pump know.

    don't waste a good HO pump for that, I have several old style pumps you could use instead, if you decide to go skat get in touch

    +1, It'd probably require machining the pump for the larger bearings.
