    2004 GTX Limited Erratic RPMs

    Need some advise on my 2004 GTX limited 185 SC. Starts up fine but only runs about 35-40 mph at WOT and the RPMs are very erratic (6400-7200) It feels like it wants to go but dosen't. After running it for 30-40 minutes, the ski seems to be back to normal. Any ideas on what could cause the long warm up period?
    Thanks in advance.

    Remove and check your SC NOW! I had an 05 that had the same exact symptoms and the bearing failed in the SC and caused the wheel to rub the SC housing which caused the RPMs to vary up and down. I was lucky, didnt loose any bearing balls into the engine.

    Also seems from other posts I have read that it is probably a supercharger issue. Are there any motor issues that could cause this other than the supercharger?

    Maybe a faulty injector, or bad plug. But if that SC still has the ceramic washers, you had better get them out ASAP or expect repairs to be more than the ski is worth... Ron
