New GS owner here. Had my bike a week and enjoying it immensely. One thing is bugging me. There is a whirring noise coming from what seems to me from under the tank, the noise appears ahead of me, and I am having trouble comparing it to any other noise. Whirring, a hair dryer? Its actually quite loud and is driving me nuts. Apart from that, the bike would seem very quiet and ear drum friendly. Can anyone tell me is this usual? Thanks.
