    rejetted carbs on rx but no extra mph

    i rejetted the carbs on my rx with bens setup with out the accel pump, has good holeshot and mid range pull, but i still top out at 60.5mph at 6750 rpms. on my xpl i revved an extra 200 rpms wit the jet kit. i have the same impeller on both. i got it to 6800 the first time out after rejet, played wit the water reg valve cuz it was all the way screwed out, so i put it flush, and i think thats where the loss is maybe? does the reg valve effect rpms? not the raves because i tried the ones off my xpl and same result

    Yes, it does. Out increases max rpms, and there is a fine line between getting them and burning couplers. Always make a pass after adjusting, I think 2 clicks are all you can get above flush to prevent it from melting one.

    Your gonna learn that not every setup is good for every ski......

    The RX has a larger wetted hull surface for starters and even the prop off your XPL may be a bit tall. I usualy run the water regulator about 1 turn above flush.

    With 167.5s closed your revs should be up near 7000 with 87 lows set at 1.5 turns with stock N/seat. I personally run 165 s closed with 95 lows with no pumps.

    I would say your prop is a tad to tall for your pump. From memory the taper on the pump nozzle is different to the xpl so your revs will be different as well. You cant compare the two together as they are so different in design. Rebend your prop to suit Try it yourself its easy.You need one of these in the picture

    found the problem guys.......it revved 6750 before jet kit, 6750 after jet kit, i might have seen 6800 once. well i put a wedge on and seen rpms drop to 6400, i was mad as hell when i seen that, then i pulled the springs out of the raves and it hit 6880 rpms at 62mph on gps, so i take it i need to change out the o rings and clean up the raves? if they open all the way without springs, its not the solenoid right?

    Exact opposite! The solenoid isn't opening or the check valve is clogged. Removing the springs allows a "bypass" to confirm the controls aren't working.

    Your raves might be gummed up.
