    What are your RPM now?

    That's a lot of prop, you may need the 87 to pick up Rs.

    for your 07 GPR, and looking at the mods in your siggy, keep that 85mm nozzle

    WFO Performance in Houston Texas has built a few GPRs running stock compression with the 85 nozzle and they are running 74/75 easy with similar mods you have.

    yur fine

    I would look into the jetworks mod holeshot kit. Island Racing sells it.
    This will help your holeshot even better. Also do you have an EFI controller ? Are you running stock or higher compression ?
    A tach is very important as you begin to add mods.
    The 87 will give more RPM's if you decide to switch

    Ok I will look into that from island racing. My efi settings are 5527 got from wfo and going to work from there as soon as I get my tach. Yes I'm still running stock compression.

    tanny get hold of carl for the jet works,also get that comp up a bit more...
    my ski spun the 14/20 better from about 15 hours up,might have been in my mind but sure felt better...
    jims 1300 does a great job on the stock head.....
