During the ride home from work this past Tuesday I noticed a rattling noise which only manifests when the clutch is fully disengaged, like when I'm on the brakes and downshifting multiple times before a red light stop. I didn't notice anything on the Tuesday morning ride in. There's nothing when the bike is idling (clutch in or out) or under power. I feel it's coming from the clutch or engine area but it's hard to isolate it as I have to be moving to hear it. Bike is an 08 FZ6 S2 model. I'll get it looked at in the next couple of weeks but thought I's see if you foccers had any ideas what it might be and how serious, as in, should I stop riding until it's sorted?
