So just to get this started I will post the couple of websites I have used for farkles/mods up to this point. I loved the old farkles page and hope this one can one day compare.
SENA SCM10 Dual Wireless Intercom system: www.radiorider.com Tell them you are a member of the Concours forum along with what year bike you have and the color and (as of 6-7-2011), you get the dual system for $275 including Free Priority S/H.
sorry it took three posts before you made the list. You should have been first. Look to Murph for whatever you need, then look elsewhere if he doesn't carry it.
Advanced Sport Touring has Handlebar Risers, Luggage Racks and very soon Tip-over Protection, GPS / Ram ball mounts and Passenger Peg Lowers. www.AdvancedSportTouring.com
