That's the age-old question right there.. On a DOHC CB750 I rebuilt, for a long time I had the bodywork painted gloss black from a rattle can. It was awesome like that, stealth mode.. No name plate/badges, etc.- just black. People would ask me at the gas station all the time- what kinda bike is that!?
On my CB900F, when I first got it, it was painted like a late-60's Buick green, which was interesting and original, but just not what I was looking for. I painted it a pearl white metallic flake paint, and I really liked the look. Later though, I got a deal on NOS factory bodywork and tank, so I went with the stock, 1982 Grey metallic with blue Stripe and Honda emblem, etc.
So, I'm probably not much help, except to maybe suggest you mix it up a bit- Perhaps a flat black tank, with gloss black scallops? That might be cool..
