    750sx '92 keeps hopping what to do

    Hi Guys,

    I am from holland and new on this forum. I ride stand-up jetski's for many years.

    A friend end of my has an 750sx '92 it has an brand new engine, but it also has a problem. If you ride on it it keeps hopping. This is very annoying. I advised this vriend to try an other rideplate and intake.
    It has already an skat-trak 9/17 steel impellor
    a jet dynamics concave rideplate
    and a jet dynamics intake

    no matter what i do it keeps hopping, i try to put te tank as full as possible.

    Does anybody here has an suggestion, how to preventie this hopping?

    I am a pretty experienced driver an know how to drive my old 750sx which does not hop at all..

    I am looking forward too your reactions solutions

    I was under the assumption the 750sx was just known for porposing. Atleast my 95 sxi did it also. Xxx2 is correct try shimming the plate
