Like you I bought the Basic F6B. Before taking delivery I had the dealer install the taller OEM windshield and passenger back rest. Once in my hands I started to equip the 6 to my liking with both "home brewed" and "aftermarket" accessories. First up was the center stand (e-bay), Go Cruise Throttle Lock, Grip Puppies, Kury Highway Pegs, Cruiser Bag (re-used), Luggage Rack (Home Brewed) and a extra GL1800 Rear Wheel with General G-Max Car Tire. In retrospect, I have no regrets in my decision to upgrade from my previous Yamaha RSTD (a great bike in its own way) to the F6B. Both bikes were identical in weight but the 6 carves corners like a sport bike due to its low CG.
As you have the Basic I would highly suggest one of the first items to acquire is the center stand. It makes oil changes a snap and its great when performing mods to the bike when its in a true vertical position. Next would be the tall OEM windshield with vent. I've. had several occasions to use it on 90+ degree days and it provides some great air flow to the face and chest. Grip Puppies and Go-Cruise would be next. After that who knows but you
Congratulations on your new bike and enjoy!
