    Question Ultra 250X 07 Not reaching the top speed

    Hi there, I need some advise on my jet ski , the problem started with a broken stuck spark plug; I had to hauled out and pulled everything apart, I did it with a book, replaced everything the book says and marked all hoses and conectors, after I completed the project, it started all good, everything sound good, but when i went to ride it, found out that the top speed is only 35mph (fast key) with no power when pinned, theres no misfiring or boging, or nothing, sounds really strong, I'm thinking that i have misplaced a hose or connector or something, any advise would be really appreciated.


    Thank you in advance.

    Check:

    all hoses are tight, especially to intercooler and supercharger;
    to make sure air intake horn is not pressed against hull impeding flow;
    SC belt is aligned and in good condition--what is boost pressure?
    intercooler to make sure its clean;
    spark plugs to see if fouled, possibly replace;
    whether airbox vent tube has fluid in it;
    whether batterry terminals are tight;
    whether you have fresh gas.

    I'd checked hoses, spark plugs, intercooler fired up everything sounds good, a lot of power I will go to the bay for a test, and see what happens.
