If when you lightly load up the engine by letting out the clutch at idle against first gear, the sound disappears or you raise the RPMS over 2-2.5K, the sound disappears then it is the idle hammer. And is inherent to the V-twin particulary those with a long firing interval, 450 degrees for the 1000.
If it doesn't fit the above I would guess the maybe idle/scissor spring at the primary gear or maybe excess wear to the clutch basket and your hearing additional clutch rattle, but again think of a Ducati and the noise the clutches make on those bikes even though they are dry instead of wet as on our bike, they make a hell of a racket due to the V-twin and firing stroke loading/unloading.
