Considering it has a cutaway cover, that doesn't sound too bad. I've tried putting packers around the outside of the plates without any reduction of noise, just chewed up the packers !
The Kawasaki 350 Avenger used multiple rubber pads between the plates, supposedly to stop plate drag but I wonder if they had the same noise issue as BS. Not been able to find any details of how they were fitted.
I'm told our clutch is quieter than the Ducati dry clutch, anyone confirm this
