annoying vibration

[standardryder]

I have an 05 yfz and just recently I started getting a high frequency vibration in high rpm. I cant feel it, just hear it and its annoying the crap out of me! Mostly because I cant find out where it coming from, checked everywhere. First I though it was mid-header where the two pieces come together but I through a clamp on and still there. I ran out of ideas, anybody else get this? any suggestions?
I took a video, its hard to hear cause my camera sucks but its there.

Crazy thought, but check your swingarm skid plate. My PRM skid plate started to vibrate up near the front of the swingarm over time. I couldn't hear the vibration in the video unfortunately...

Hmm well I did throw a new singer guard on few weeks ago it could have loosened up, definitely have to check that out. And I went through the motor mounts, but only tightened up the bolts where the propegs mount to so ill have to look that over too.
Thanks!

That seems to happen alot! I toke my YFZ out the other day and was hearing a weird vibration... Sure enough, it was the rear skidplate.
