Should be behind one of your sidecovers. I f you did'nt get a manual w/yor bike then order one from your dealer. It's an invaluable tool....Good luck to you friend....Tim

Even though you probably don't have that many miles on the bike, or if you do have a lot riding time on it, it sounds to me like you need a valve adjustment. That's a high reving bike for that engine that works pretty hard so you might have 1 - 3 loose valves.
