How should the powervalve function (open/RPM) on the trailer/hose?
The powervalve in my GP1200R (01) only wants to start moving open at max RPM, and it doesn't seem to move that much, is this normal? It opens and closes pretty quick but obviously I don't want to hold it revved with no load so I'm only giving it a full throttle blip for a couple seconds. I thought it should start to open in at least the upper midrange? Is it normal for the powervalve to only start to open at max RPM/fully wound out? And how much visually should the pulley be moving the servo cables hook to? Or does the motor need to be under load in the water for the power valve to open up fully? Thanks...

Here is a test for the servo motor. you can also crank the motor shortly, shut it off and the servo motor should cycle a couple of seconds after the motor is shut down.

Ya Ive revved them up on land before. the valves dont seem to move much til you put a load on it at high rpms
