BZZZZZZZ:
I removed the plastic bits on the "inner fairing" panels (to the
left and right of the bars and the center tank cover section. I put
a small bead of silicone caulk where those pieces meet the bike, let
the caulk set up for ~45 minutes, and replaced eveything. Absolutely
NO plastic bzzzzzing at any speed anymore. This is one really quiet
bike.

--------------------------------------

=> By the way, I hate that buzz! In the past I've put black electrical tape
=> around the two tabs that are supposed to hold that cover tight. Have you
=> found a good way to keep that thing from buzzing?

Yes.

Remove all the panels around the top of the tank and the sides
of the instrument cluster.

Apply a thin bead of silicone caulk to the edges--where it won't be
seen. It doesn't have to be a continuous bead. 

Let the caulk "set up" until it's got a skin and is tacky--sort of
like soft bubble gum. About 10~15 minutes.

Reassemble.

I've been _completely_ buzzz free for about 2,000 miles, including
lots of bumpy pavement and NYC potholes.

=> 
=>    I also occassionally get a buzz from one of the two black plastic
=> column-like pieces that come up the edges of the windscreen. They are each
=> held by one phillips screw. My only cure for those has been to loosen then
=> retighten them.

Same cure as above. Also, since all those plastic parts are soft, I
wouldn't want to loosen and retighten them too often. Be _very_
careful about overtorquing. Remember the mechanics rule...tighten
until the bolt snaps, the back off 1/4 turn.

=> Well,
=>    It turns out I go in and out of those panels fairly often, for one reason
=> or another. After a while, the permatex solution gets to be time consuming
=> on reassembly, and also starts to be messy after a few reassemblies. I'm
=> sure it works great though.
=> 

I remove the panels too. I'm NOT suggesting using permatex or
something sold as an adhesive, but ordinary household (bathroom)
caulk. It remains slightly pliable, and doesn't glue the parts
togther the same way as a good adhesive. In fact, if you let the
bead cure enough before assembly, you probably don't need to reapply
the caulk at all on subsequent reassemblies--it remains on one
piece.


=>    I already have 66,000 miles on mine, and when you pile up miles quickly,
=> you end up going "in there" more often.
