I just bought gold pegs on eBay a couple weeks ago. forwardmotionmc was the seller. Send a message asking for them. ($26 w/shipping) Gold CRG roll-a-click levers.
Gold sheathed stainless brake lines. I think Galfer has.
There's a couple brands of gold rearsets available from various brands.
Gold bar-ends. Lockhart Phillips has these.
Vortex gold gas caps.
Gold sprocket from sprocketspecialists.
Gold chains (D.I.D., Renthal, EK)
Micron gold exhaust.
Gold rim tape is an option. tapeworks.com has a ton of colors.
There are a lot of options. Just start looking at some of the bigger aftermarket sites like indysuperbike and kneedraggers, etc. Other than that you're gonna have to start painting and powdercoating. Just don't over do it!!
