Bike has 8600 miles and when accelerating normally, there is a buzzing, rattling noise that starts exactly at 3000 RPM. It sounds like it could be something in the fairing buzzing from vibration. No noise is heard unless the bike is being ridden. Nothing by just revving the engine. I took it to the dealer and both the service manager and a tech heard it and feel like it is in the engine. Bike is still under warranty until May 15. They will watch it and recheck at the 10,000 mile service. Any ideas???
