    you may have a faulty servo motor, you can buy a new one but i recommend you check thats what the problem is first....

    fyi they are known to fail

    it could also be the conector.
    Follow the cable from the powervalve motor, and you will come across a tringular three pin conector. Strip clean and reassemble with dialectric grease to see if that cures it-it sometimes does.

    The power valve also shuts down when you hit the rev limiter, what RPM's are you turning?

    What happens when the power valve goes "crazy"? My GP1200R was running like crap last time out, wouldn't take full throtle at low revs then would come on like normal all of a suden. I was going to change the plugs.

    That sounds like the valve is stuck open, it will bog until around 4500 RPM then take off like a raped ape?

    yes, had to feather the throtle to get ot to run at all in the low rev range. got this ski when it wasn't running, got it going took it out twice, ran fine , smooth, linier power. last weekend it ran like crap, the fine at wfo, would bog and not idle well.
