edehn,
I think those inner fairing parts are for sale right now on ebay.

Basic maintenance is pretty straightforward. I strip my 1200 down and take it to the shop for valve adjustments tho. If you have the tools and a set of shims you could do the valves yourself, it's not rocket science.
Some aftremarket parts that I know of:
exhaust (

seat (Corbin,Sargent), jet kit & air filter (K&N), and suspension upgrades (Race Tech, Penski, Hagon)
I've had good luck finding parts on ebay but you have to be patient, from time to time someone will sell parts off a wrecked or salvaged bike.
Welcome to the group,
cheers,
