engine noise - Breva

Does anyone have any idea of what seems to a spinning vibration noise on my 1200 breva you could say it sounds like a ratchet type of noise when I pull up and pull off up to around about 3000 revs doesn’t seem to be effecting the running though sounds weird

If it is making the noise with the clutch lever pulled in then is clutch rattle, perfectly normal on the twin plate clutch set up, should go away when you let the clutch out.
