Hi all. Hope everyone here has been well this summer. I have a question, my bike, on occasion, appears to have begun making a "whirring" noise when the throttle is moved. Sounds like wind through a channel of some sort - somewhat high pitched. Ive noticed no decrease in performance and no lights have come on or anything. Bike runs great, but is getting older. Any thoughts? Its a 2008 Vulcan custom, fuel injected, liquid cooled, with a belt drive.
