    Powervalves doing Random things!!!

    Hi Guys,

    We have an 02 GP1200R that's playing up, have rebuilt carbs and pulled and cleaned the power valves, however when it's in calm water the power valves operate as they should and open up, but as soon as you hit a patch of rough water they shut down, and won't re-open until the water is calm again... It's totally repetitive (i.e not a once off) and I am running out of ideas as to what it could be. Have swaped the powervalve solenoid to a known good one and no difference.

    cheers

    James

    I think the ECU that also controls the powervalves are shutting down (closing) as your motor bumps the rev limiter as the ski comes unhooked in the ruff water.

    thanks, thats what it feels like, hit's a limiter and then won't come right till pump is fully loaded again..

    Is there a cheap and easy way to bypass this from happening?

    No cheap or easy way, options are an Advent Ignition or Gas Valves. But honestly I would work on the handling of the ski for better hook up, what type of intake grate are you running?

    Doesnt Pro Tech make a power valve controller that works with the OEM computer?
