Welcome from Centreville (home) and Falls Church VA (work).
The guys @ Colemans Honda are old bike nuts, go make some friends down in parts and I bet they will be helpful. In my experience you should avoid Crossroads Cycles at all costs, they botched up my bike big time.
If you ever want to get together with another local SOHC nut, get at me, I work right by where you live, and am always down for a cold one with another bike nut.
