    2007 250 Ultra speed loss with age

    I have a 2007 Ultra 250

    200 hours , total stock, other than oil changes , plugs replaced, and checking Super charger belt tension everything on the ski is as it was
    3 years ago.

    Top speed is 62.2 calm water 3/4 tank and 280 lb rider.

    What things should I check to see why top speed has dropped from 65.4 , or is it just age on the ski?

    thanks for your help

    Maximum that I can reach with my kawasaki ultra 250x is 40mph. Is this ok? Shouldn't be faster by default?

    Thank you,

    Is this GPS speed or from the dream-o-meter?

    I thought these 250's ran faster then that?

    With 200 hrs I am sure your rings are starting to wear and you are starting to lose compression. Have you done a compression test on it yet?

    It is from dream-o-meter. I have 45 hours so far with it. When I start I can feel the power, but running seems like should be more speed. What speed others have with the same model?

    Thank you,

    the only way to solve this for both the OP and the hijack is with a gps. stock speed should be about 65 to 67 mph. Rpm should be about 7500 to 7800.
