On my 2010. I've got a strange noise coming from the bike. Almost sounds like a knackered bearing kinda noise but it's intermittent. It only makes the noise when in gear and driving and even then not all the time. If it is making the noise and I pull the clutch in it stops immediately and then comes back when I let the clutch out. Sometimes I'll be riding along in gear with no noise and then it just starts. Higher up in the rev range I can't hear it. Whether that's due to the increase in noise from the engine or because the noise isn't there......couldn't say. Anyone got any experience with anything similar?
