So riding yesterday, a couple of times, when decelerating or in cruise, I hear a noise, it's loud I can hear it over the engine. Sounds like a tin can being kicked down the road. Or a paint can being very vigorously shaken but it really was quite loud. Thought I was dragging a tin can and it was bouncing around under the engine. It seemed to stop when I pulled the clutch in. At standstill it seemed okay.
Clutch works fine. Not stuck in any gears, it finds neutral as easy as it ever has. Will also try the 5th gear roll it back to see if that sorts it if it is the tensioner.
I'll check the tensioner drop tomorrow. Was loud tho. Not had chance to try the bike since to listen to it more. 2011 R3R 33k miles.
