The fenders and gas tank for your bike are available thru the aftermarket.
(Maier racing & Clarke manufacturing.)
Side panels would be honda o.e.m. or used thru a bike salvage yard.
The chain tensioner (guide??) and airbox would be Honda o.e.m. or salvage yard.
Brake pads should be easy and comonly available thru your local bike shop.
For salvage yards try "motorcycle salvage" in a search engine like "yahoo", or "search.com".
Good Luck! :D
