You don't say anything about the mileage, but like "goto" mentions, I'd check the rear oil then pull the rear wheel assembly and check all the "splines". Look at the "drive flange teeth". No grease, teeth look rounded??? That's the 1st possible noise/vibration. These DO wear faster if no grease (moly-lube).
This drive flange fits into the final drive unit and it has "teeth" in there for those from the drive flange. They could be "rounded" as well. These two parts get the power to the wheel/ground. If you need to see all that's in the rear drive unit go to: www.ronayers.com They have a parts fisch for your year bike and exploded views of this area(rear drive unit).
Other possible vibration/s causes maybe the "rubber cushions" are worn out in the final drive unit. Brake pads may be hanging as well. Again look at the Ron Ayers site if you have no service manual.
I replaced my drive flange and ring gear about a year or so ago. Had the vib/whinning sound while riding on my 95, 1100. It's not a common problem...but it do happen.
