Grinding noise/feeling around 6000rpm

[Dead Eye]

Are you certain its from the engine? Only reason I ask is that the few rattles and vibrations I've had have been due to the fairings / plastics - last one was the metal cone inside the left hand light housing.

Not really sure on what else it could be as if it was related to the chain / sprockets or front wheel etc I would expect the vibrations / noise to correlate more with road speed and not be related to the RPM of the engine.

If it is the engine I guess it could be something like the water pump, alternator, oil pump etc but this is incredibly unlikely as its very rare to hear of these parts failing.


Oh, actually, something I just thought of - what about the clutch? Have you checked the clutch plates for wear?
