I didn't like how loose my gauges were so I fixed them last weekend so this is fresh in my mind. Here's what I did:
-Remove windscreen
-Remove both of the black fairing covers on the left/right side of the instrument panel (the ones that come down across the top of the fairings)
-Remove the 2 screws beneath the windshield and the 2 black plastic "rivets" holding the plastic panel beneath the windshied. To remove the rivets, just use something to push on the center of the pin until it "pops" in a little, then pull out the whole rivet. Then remove the black panel.
-I think the instrument cluster itself is just held on by 3 small bolts (1 on top, 2 on the bottom) that you will need an 8mm (might have been 10mm) box wrench to remove. They are mounted on some rubber pieces. A magnet is helpful to make sure you don't drop the bolts.
That's as far as I went as I didn't need to remove the cluster but that should point you in the right direction. BTW, I firmed up the gauges a little by adding a thick nylon washer between the bolts and the rubber mounts.
