Developed a heavy thumping vibration ( Not a tinny feel as if plastic rattling) when decelerating that is getting worse. Especially noticable at higher speeds say 75mph. At lower speeds below 60 it isn't quite as noticable. The vibration is something that I feel not hear. If I ease off the throttle I can minimize the feel. High frequency, I'll compare the frequency to a machine gun. I've had cars with worn u-joints that felt similar to this. Any ideas or experience with this? Bike has 46k miles.
