I know that some where along the track this has been covered, but my bike is going in for its 12 month service, and im considering have i tooth added to the front sprocket, as i do alot of long distance riding, and the bike is to revvy for my liking at highway speeds. My question is, has anyone done it, if so do they recommend it or did you go back to standard?? Just want to make sure, so that i dont waste time or money.. Cheers.
