When I bought my bike I didn't like how loose the cluster was. If you remove the windshield and the large black plastic piece underneath it (I think you also need to remove the 2 black side covers that run from the gauges down to the gas tank), you'll have access to the 3 (I think) nuts that hold down the instrument cluster. I removed the 3 nuts and reinstalled them, adding a nylon washer to take up some of the slack. The washer needs to have a large enough ID to where it will go over the stud that the nut bottoms out against and compress the rubber bumper. It's difficult to describe without a visual. I think the washers I had on hand were about 1/8" thick and had an ID of about 3/8".
I didn't completely remove the cluster so I can't help you there, but accessing those 3 nuts is a good starting point. You may just need to disconnect the harness and lift it off after that.
