    250x Top Speed Probs

    Hi i have a 2008 ultra 250 x with 60 hours and some mods:
    -riva rideplate,
    -solas prop
    -r&d grate
    -09 pistons and cams
    -6 timming mods
    -riva free flow exhaust and wb
    -and some others.

    My probs is that my toop speed was max 53 mph about or 80 km\h.
    max rpm recorded on the gauge are 8650 (it seems me too much).
    but seeingthe rpm during screen i can see about only 6700 about.
    Is it impossible to have such this rpm......the ecu hasn't got a rev limiter?
    Why my ski go so slow? what to check?
    no strange noise, no strange things...

    Thank you

    THAT'S RUST is so bad...man do you wash you ski after each ride, spray the engine..and internal compartment "maybe" as you always says or maybe not..I suggest to do major check up and maintenance job on you ski
