Hi, just thought I'd finally chime in. Been lurking ever since I ordered my red/black 07 FLHTCUSE2 last August. Sold my last ride (silver/black 03 FLHRCI) to a good friend of mine. Took delivery 2 weeks ago. Haven't had a chance to try it out yet - still snow on the ground (just got 12" more on Sunday). That's what I get for living in Eastern Canada.
Thanks to the all the great info I've been able to filter through from this site, I've already ordered a quick detach kit for the tour pak, a corbin classic solo seat oval backrest, and touring pillion, sissy bar with pad, Nolan n-com helmets with the J&M headsets, I'm about to contact HD-DUDE about a Hawg-wired setup and I'm ordering a Garmin Zumo as well. I've spoken to the service techs at my dealership about a SERT, True Duals and Air. They've said to put a thousand mile on the stock setup first, then we'll upgrade those as well.
For a bike that I thought I would not mess with much, hanging around here has pretty much changed that theory. Love lurking, but when I've something useful to add, I'll give my 2 cents.
