On my 16 Tri i have noticed that when im riding next to a curb or highway wall anything that will reflect sound that at any speed where i am not on the gas or off just maintaining speed there is a rattle towards the rear of the bike.If i pull the clutch in it goes away or if i accelerate it goes away,never really noticed it until i put the the polished discs behind the wheels,will take the discs off and try it.Anyone else have this issue.I had the bike up on the jack and there seems to be a lot of backlash in the axle pulley assembly i checked a new one at the dealer and it also has some.
