    07 gpr mods

    hi.
    Wondering if anybody can help me? I recently fitted an intake grate,ride plate and extended nozzle (all pro-tec). The result was my ski started to propoise alot at high speeds, can anybody help in telling me why?. I have since removed the ride plate and nozzle and left intake grate on and ski runs fine again.

    Step the sponsons. This means

    Take the sponsons off, in the middle bolt hole make it one hole instead of two. Then have it angled so the front of the sponson is up, back is down.

    Does stepping the sponsons change the handling? I like to play around from time to time and I like my ski to slide at low speeds.

    Yea, but so is drifting! lol
    Do you loose more speed by stepping the sponsons or shimming the tabs?

    I wanna try running no sponsons to see if I can do a 360

    Yes, you will lose speed. Not much, i would say .3 by stepping. The more you shim the tabs the more you lose. Every does the sponson thing though...

    Thanks for the help, i will try stepping the sponsons.Does the extended nozzle reduce top end speed? What other mods should i install? I ride in the open sea,lots of wave jumping and high speed runs.
