    Unhappy RXP Stage 1 Installed Lost Rpms/Top speed

    Hey guys,
    Just got my 06 Rxp back from the dealer with the new stage 1 kit installed. Took it out, noticed better acceleration etc but rpms topping out between 7800-7860, on gps was only getting 67mph compared to 69.5 bone stock. Anything simple they could of done wrong that i can fix so i donít have to take it back to the geniuses at the dealer ... thanks again for all our help in the past.

    Water temp was 68, air temp was 70 @ sea level

    sounds like you may need to tweak ur prop a little.

    You need a prop
    When I went from stock to aftermarket I needed to
    prop to a 14-19r, though I used skat.
    Not sure what you have.
    Also tested a 14-20r special built and bent and it worked ok.
    Also tried a 15-21 special bend and lost to much rpms.
    So I would say check your prop, if you have a new one
    that should have been checked before install.
    But always check a new prop for proper pitch before installing,
    Most are off a degree or two out of the box..

    Did the dealer install a new wear ring when he replaced the impeller? If not yours is more than likely toast.

    Also, take 2 mm out of the trailing edge of the impeller and it will really wake things up
