f4i vibration noise

i have a vibration noise on my 02 f4i thats pissing me off but for the life of me i cant figure out what it is....it is not a constant noise and usually is most noticable between 5-8k rpm. its not extremly loud like a metal on metal clanking but enough for me to easily hear it over my shorty exhaust..basically a buzzing noise on revs/acceleration. i know its basically impossible for anyone to figure it out without hearing in person but since im new to sportbikes in general i figured itd be worth a shot to see if its possibly something common or if i could get some typical things to check.

i appreciate any help

search for CCT

*punches himself in the face*

looks like im not the only one with this problem DOH...i shouldve done some searching beforehand...i apologize for beating the already dead horse.

 i appreciate it though

Check the CCT. That seems to be a problem with these bikes.

I had to post that picture, I had someone do that when I asked a question in another forum.  No worries.  Just a funky noise our bikes put out.  Just hmm while you are in that range.
