The last couple of mornings when I fire up my bike for the first time and shift from neutral to first I get the clunk as if it's shifted gears but first doesn't engage and the "N" light stays on. I have to shift into first a second time to get it to engage. So far this has only happened when I start the bike for the first time each day. I've also noticed that when I clutch in in neutral there is a faint vibration thourgh the bike that I haven't noticed before. The vibrating doesn't go away even after the bike has warmed up. I ride an 06 600rr, is this anything I should be worried about?
