    GP1300R ported single pipe prop??

    GP1300R ported single pipe prop??
    What prop pitch are some of you ported 1300 single pipe using, and what rpms are you getting? I'm using a 14V setback Magnum pump on mine and I would like some feed back from some of you who had tried different pitches and pumps.

    about 7150 rpm is considered optimum for a ported 1300 as far as I can recall.

    people i ride with are generally running 14/23's or 14/24's (or bigger) if they want top end speed but lower pitches for CC sort of use.

    add 1.5 mm pitch to your trailing edge. drop the rpms down tp 7150. has the heat & humidity arraived in Guam? if not then add 1 mm and wait for the heat to take the rest of the rpms away
