Thanks for the advise fellas. I think I'll be checking things out in this order: Lube (silicon) the rubber bumper and check the clamp on the exhaust; check whether or not the belt is loose; then the chain. The breaks look fine.
If anyone else out there has any idea of what it might be, stick it to this thread just in case the other guys who are experiencing can still get the info.

Mine was on my left side muffler rubber only and only at idle. About drove me crazy. I'd be good till the lube wore off ...

Quick update: It's not the rubber bumbper on the exhaust mount. I took the rubber piece out yesterday, cleaned and lubed it, and no change at all. Looks like I'm on to the belt.
Anyone have any tricks on gauge the tightness of the belt without buying the HD tool?

I've been battling this "chirp" for a while now. Mostly it has been the rubber slip on mounts. I'll buy some new ones and see if that helps when I do my 50K service. I'll also be checking everything else mentioned in this thread. As part of my 50K service and in an effort to eliminate this noise once and for all.

Last update: Success! It's fixed! Believe it or not, the dealer service manager new exactly what it was. I called the dealer today to see if they had a belt gauge in-stock. I was transfered to the Service Manager so I just explained everything to him. He told me to buy some "Poly-Lube" ($4.00) and put it on my belt. He said 90% of these types of chirps, that he sees/hears, is caused by a dry belt. After work, I picked some poly lube up, put it on the belt, and went for a ride...NO DAMN CHIRP!!!
Hopefully this helps you guys who are still chancing this elusive chirp.
Good Luck, thanks for the help...RIDE SAFE!

Mine started chirping today & loudly. I noticed it during decelleration. At first I thought it was another vehicle until it did it again at accelleration. I only noticed it between like 20 & 50 mph. I did run it up to 50 mph & killed the engine, then allowed to bike to slow down. It still did it. I figure this eliminates the possibility of egine/exhuast noise. I checked belt tension & it's gtg. Brakes are all new, less than 500 miles but I checked all the hardware. I'm thinking of trying this Poly Lube. The noise does appear to be comeing from the left side of the bike & at $4, it's not a gamble.
Any other ideas?

It was the left side top muff bracket.I squeezed the metal bracket with Chanellocks to tighten up gap between the bracket and rubber piece.
