    RPMs

    Hey guys on my wifes 99 GSX LTD, when i ride it i cant seem to get it to go past 5020 rpms. 42 mph. WOT is still 5000-5100 rpms.
    Any ideas why it wont go further? i was thinking rev limiter or something.
    Mine goes like a freaking banshee and i think hers should be a little faster.
    Nothing seems blown and they start and run fine actually, just that minor thing.

    thanks for any help and as always ride safe!

    Same problem with my 96 gsx. I have no clue what it is, and have been stumped every since. Mine actually doesn't get above 4500 rpms, but close enough!

    Not trying to jack the thread OP but we have identical problems!!

    I have cleaned my raves and boy were they nasty. At first when I put mine in water it will go up to about 6k then after a few minutes it will bog down to the 4500k. Still rave valves?

    Thats with closed rave valves .. When the raves open it should be spinning around 7k
