hi everyone ive got a speedfight 2 Air Cooled 2005 yesterday i noticed when i let the throttle off the revs arent going down or when they do are taking a long time to go down so the bike is staying at a lot higher revs. we thought it was an air leak but have had everything apart and its not that, we've also changed the crank seals and thats made no difference cant think what it can be now, anyone know? any help will be much appreciated thanks brad
