Vibration/rattle at 9K rpms
 

I have a 2007 Honda CBR600RR, which only has 2700 miles on it. At 9K rpms, in any gear (Short of anything higher then 4th, cause i'm not crazy enough yet), it makes a weird vibration/rattle sound. I don't feel any loss of power. If I rev the bike to 9K --> 10K it doesn't do it. It's only when i'm in gear. Could this be a bad cam chain tensioner, or could it be the windshield? Any thoughts would help. Luckily it's still under warranty, though i'd prefer not to take it in if it's a cheap fix.

Thanks

Upon closer inspection of the bike i found out one of the bar ends fell off, as the screw i used was too short. Off to Ebay.

Found out one of my bar ends fell off. Shouldn't of purchased too sort of a screw at OSH.
