    Stock 07 RXP Increase RPM and top speed

    Ok I have a Stock 07 RXP I Have a few questions

    I know the Stock speedometer isn't always right, But does it top out at 70?

    I'm Getting about 7500 @ 70mph and with about 1/4 throttle left If I pull it all the way back I don't really get anymore rpms or speed maybe about 7800 rpms and same speed.

    The Cable can probably be adjusted as the butterfly is still not completely at 90deg angle.

    Id like to leave it pretty much stock for reliability and cheapness, Is there anything I can do to get a little more out of it and not sacrifice reliability and a whole lot of money.

    I'm guessing maybe adjust the cable and repitch the prop???

    With Bullet on this one. How many hrs on charger? You should be 8100 all day. And yes, speedo is topped out at 70 and is way way off from gps. About 8mph.

    If the mods to the skis are equal, what years and models tend to be fastest top speed? What models tend to be tough to get speed out of?

    If hes pulling 75-7800 RPM his charger isnt gone,slip could be low BUT its not gone....Get the butterfly aligned,have the slip checked and put some new plugs in her....IF your Speed and RPMS dont come back o would start looking in the pump area for a dinged up prop,worn out wear ring.....

    you should re-check after a complete rebuild. Beat it's a little low on slip.

    Look in the GH store. you buy 2 shims for like 2 bucks!! I bought a bunch just to have. You will also need the sc mounting plate, gear wrench and shaft wrench and a good dial torque wrench. Might be a little cost up front but you will have them forever. Or if in doubt, send it to Jerry.
