I've got the '11 RGU, 103/6spd, 3500 miles. At the 1K service went full Syn 3. Starting to hear and feel strange stuff that dealer says is normal. When rolling off throttle there is a whine (no, not coming from the back seat) that I first thought was dust on brake pads. It stops if I pull in the clutch. When I roll on the throttle there is a bang or pop that is almost as defined as if I had just shifted. Yesterday I had 15 miles of rural roads before going through town. By the time I got through town I thought the darn'd bike was coming apart, so got on the freeway to go to the dealer. 10 miles at freeway speeds, and the noises QUIT! Is it normal to have play in the drivetrain when loading/unloading power?
