actionman124 Posted June 11, 2010 Share Posted June 11, 2010 I have a P reg Thunder Ace, the rev counter is playing up and wondered if anyone can throw any light on it. The needle goes up to 7000 then drops to 4000 then down to 0 but only when the bike is moving...on the stand , it moves as it should...any clues?
