Okay, so its a 1991. The power valve is not operating. Yet, when you take the little brass ring off the power valve rod you can pull the lever sticking out of the case that actuates the power valve and it snaps back as though it is operational. Also you can pull the power valve rod sticking out of the head and slide if back and forth with ease. We've also confirmed the the power valve itself is working as when the bike is idling you can slide the rod in and out of the head and the power valve opens and closes. very confused as to why the power valve actuator in the case cover does not actuate and open the power valve when everything is hooked up. We've check the manual and all. Any thoughts? To me it seems as though the power valve spring is wayyyyy to strong and just isn't letting it open?
