    2007 rxp, only 6000rpm, then slugish?

    hey guys,
    I havnt ridden my rxp in a few months, but i do start it up every few weeks to make sure the engine is running fine.
    Took my ski out yesterday, i had to top up the oil, and the engine coolant before i took it out as both fo them were low.

    When i accelerate, it has lumpy spots, sounds like its running on 2cyls sometimes. Then when i pull WOT, the ski does the same thing, and sounds like its only running on 2cyls.
    From 3500-6000rpm it runs fine, but after that it just does not perform, sounds like its only running on 2cyls again.

    What could my problem be? Any help appreciated!

    Maybe your supercharger clutch washers took a crap? Will your ski go beyond 6700 RPM?

    I was thinking it could be the plugs, or the fuel that i put into it?
    I sucked 40L of fuel out of a gsx limited i just bought, as it had a full tank, but who knows how long it had been sitting there for.
    i will change the plugs, put new fuel in and see what happens.
