YPVS TONE Posted June 21, 2009 Share Posted June 21, 2009 When you turn on the ignition the valve will rotate anticlockwise to the fully open position i.e with the pulley U lined up with the hole .Now when you start the bike the valve should move clockwise to the low position. How high are you revving it as the valve won't start to open (moving anticlockwise) until about 5500 - 6000rpm and upwards. Tony. Link to comment Share on other sites More sharing options...
