I am blessed with a great parts guy at my local dealer, and he happens to ride an HD touring bike. So he has all of the answers i seek and normally some good recommendations too.
I stumbled into a different dealer when i was pricing out speaker upgrades, after 2 minutes I couldn't listen to the BS they were spewing any longer. At the end he handed me an accessory catalog and said here, you can see everything we offer. I won't go back there even for a tail light bulb.
