I'm at about 2000 miles on my o6 R1. The other day I left work and got on it a little in first and second then let off. (about 45-50mph) As I leaned back and let go of the bars (as I often do in the same spot) I noticed a vibration. I looked down and the bars were slapping from side to side pretty bad. Then today again. Is this normal or is something wrong? This is only my second bike, but on my FZ1 I could let go of the bars anytime over 20mph and never had so much as a twitch. And that was with no dampner.
