When you first turn the key "on" the power valve with go to its start position. If when you turned the bike off the valve was already there it wont move.

To set them up you need to disconnect the TPS (right hand side under the seat) and then turn the ignition "on". The valves will then move to adjusting position. Line the marks up.. or use the holes on the plates. Turn the ignition off and reconnect the TPS.

Once the bike is running as you blip the engine the power valves will flutter back and forth, that's normal.
