    Still gettin' smoked out of the hole..

    Help guys, I have a 2000 GPR1200 with the following:
    Riva 41cc 80 mm heads
    Taylor 8mm wires
    Riva Stinger 2 exhaust
    Waveeater powervalves
    13/19 solas
    r&d ride plate

    I changed out the 800 intake grate for a 1200 with little difference in my holeshot. Sounds like its turning alot of RPM's out of the hole but doesn't really get going strong until it hits plane, then it takes off really good and has plenty of top end. I really want a strong holeshot, any ideas on what to change or do?

    Also, when I try to thrash around at full throttle, I am getting a popping sound that sounds like a rev limiter. It only does it under full load and throttle when doing hard spin outs. HELP!

    the "smokee"

    The shoe has been sealed and it has the Riva pump stuffing kit...(Is that the same thing?) I'm new to the technical side of this...I'm getting tired of my friends Honda 1200 and my dad's '98 GP1200 leaving me out of the hole and I'm eating water spray! Thanks for your response....Martin

    Being the ski is a 2000 model, if the impeller wear ring has never been replaced it surely has too much clearance (out of spec). If there is too much space between the impeller and the wear ring it will cavitate coming out of the hole.

    Pump Plug Kit. It fills the voids in the pump shoe.

    If you don't mind me asking what kind of ski are you going against on hole shot.
