The picture I posted shows the powervalve in the fully closed position. (With the actuator arm disconnected as the cylinder is off the bike in the pic). The arm is to connect to the pin, with the plate in the position shown in my pic.
You can run the bike with the cover off and watch the plate move in its action. The main thing here is to note that it should be fully closed at idle (up against the bolt), and swing around as the revs increase, hitting full open in the upper rpm (other side of plate against the bolt).
Also, if you disconnect the actuator arm from the plate you should be able to manually move the plate in its motions. It should glide smooth and easily in both directions. If you have any binding or resistance you'll need to service the PV assembly.
Special note: Don't try to move the plate around with the arm attached. It will dislodge a ball lower in setup and stop the system working.
