I’ve got a problem with my zr. At 2 k rpm it bogs down . I’ve noticed that the power valve solenoid fails to move. My question is at what point (rpm)should the solenoid begin to move?

Around 7K is when it rotates. We had one bogging low & found out the cables had come off the servo. Are powerV clean ?

Servo tested good today. Cables on, power valves clean and move easily . Isles fine until 2k rpm and it goes into like one cylinder only like it’s conserving power. Thinking it could be a bad stator. Machine has 9k miles

Does not sound like a bad stator. Did you bypass the TSS [Throttle Safety Switch]?

I would hook a spark tester up to it and see if you are missing spark at that rpm. I am assuming that your track isn't seized up. You could also check fuel pressure. Some testing must be done in order for you to have some direction....
