I have a 2007 600RR with about 55K miles on it. It seems when down shifting from higher RPM's like coming to a signal or stop sign, it sounds like my fairing are vibrating causing a noise. Checked all my fairings and bolts and everything seems tight. My room mates bike does the same thing? SO I am sure some of you are too also hearing this. I am starting to think it might be the inside of the exhaust pipe or something. Thanks for any info or suggestions.
