So those rotor cover aren't just there for looks

I removed the rotor covers so that I could polish them up and just put them back on when I spoon on new tires next week.

Didn't realize that one of them is weighted (right side) and today's shake down ride showed me why. Braking produced a high frequency vibration noise without the covers installed. Kinda like rubbing your finger around the top of a wine glass to get that humming noise.

All the rotor bolts are torqued properly and in sequence. Seems odd that it would make a noise. I've seen pictures of other RSV's here without the covers but have not heard anyone report this noise before.

Ken,

I took them off my '99 as I liked the look better, I never had any issues or noises. What seems strange to me is that only 1 of them has this on it

When you take your wheels off, remove the pads, but mark them so they go back to the same side, and campher the leading edge slightly with a file. You'll find that the squeel is gone.

I'll try chamfering the edge. That's a good idea.

Nevertheless, they are going back on when I get the tires replaced. I buffed the snot out of the covers and I don't want the shininess to go to waste.

So, what DOES buffed snot look like????

No..no...I buffed the snot OUT of it. I threw it away when I was done. Messy stuff...
