    07 Ultra 250x problem

    So I have an 07 kawasaki 250x and just recently the engine wouldn't go past 5,750 rpm which is about 45 mph. I tried changing the oil but it didnt really do anything. This ski has 91 hours on it. What could be the problem with it?

    I took my car on freeway the other day it would not go past 45 mph I changed the oil but it did not do anything what you thinks wrong ?

    When asking for help try providing a little info.

    First step change your spark plugs
    Check for loose hoses and leaks
    Check your intake air horn
    Start there.
