Consider custom graphic decals to either replace your stock ones or add flashes to your existing scheme. I like the race look myself - number plates, etc,. Here's a shop I'm biased to b/c they're in my town. But there's lots of them out there. They did a few of my friends' bikes and they look pretty sick.
Vinyl Graphics are the way to go if you do thenm correctly.
I used a 3M removable adhesive for my bike that way I can change it or remove it with out damaging the paint.
Find a custom graphics shop to do the work if you have not worked with vinyl before. It's easy for me because that what I do for a living.
