Found this web site that sells colored bolts and nuts, including a complete kit for the fairing.
I think the blue would blend in nicely and or maybe the gold color on a black 04 F.

those are cool.....but would buy them unless i needed some new bolts anyway....the sprocket nuts look the best.
That is soooo pimp... but tempting...
I remember seeing a site that sold them here in the states but. Wish I could remember cause I could use some new bolts, they have some rust and would be nice to trick out with those
