I've got a '99 XL883c and it recently developed a rattle that I'm having a hard time tracking down. When I accelerate and then pull the clutch in and let the RPM's die down while I coast I can hear a weird rattle from the front wheel or somewhere forward on the motor? It's only a slow speed type thing. I checked the spokes and they feel pretty tight, and nothing seems to be loose. How do I track this thing down?
