I have a 2006 VRSCA model that exhibits a loud whirring noise that changes pitch with engine rpm. The noise becomes a loud chirping sound at between 2500 and 3000 rpm. Above that the pitch changes so that the sound becomes much less noticable. This sound occurs regardless of whether the bike is in gear moving or setting still in neutral or with the clutch engaged. Anyone notice a similar situation with their VROD?
