You looking for aftermarket of OEM? There isn't a whole lot of aftermarket for them. Absolutely no wheels, period. Winch mounts, mufflers, and hand guards are about it.
I get my OEM stuff from cyclepartonline.com or cheapcycleparts.com. There are plenty of others, but I like the prices at these two and cyclepartonline has flat $7 shipping. Some get pretty hefty shipping fees.
Oh, one thing I haven't seen mentioned regarding your original question about doing an oil change is the type of oil. Everyone has a favorite, but be sure the oil says JASO-MA
on the bottle. The oils to avoid usually say something about better MPG. They have friction modifiers that won't work with your wet clutch. I personally use Shell Rotella T6 synthetic 5w40. That way I can run it year round. I know it says diesel on the bottle, but a lot of ATV and Motorcycle people swear by it. It is JASO-MA approved.
"The Japanese Automotive Standards Organization (JASO) has created their own set of performance and quality standards for engines of Japanese origin.
For 4-stroke gasoline engines, the JASO T904 standard is used, and is particularly relevant to motorcycle engines. The JASO T904-MA and MA2 standards are designed to distinguish oils that are approved for wet clutch use."
