..sounds like its coming from the right side and only shows up when my bike is at idle with the front brake activated. Doesn't do it with just the rear brake, stops if I increase the RPMs, but leave it at idle and pull in the front brake there it is. It sounds like a screw rolling around inside the air cleaner cover. Bike is a 2008 FLHTC stock with 36K. It's never easy diagnosing a new rattle so I thought I'd check with you guys. Any ideas?
