What do you want on the bike as far as logos? If it were my bike I'd start with some number plates and then add on from there.
you could put some green on the bike.
If I had a black bike I would kind of go retro late 80's but add some flair.
I'd put a silver band across the bike and put KAWASAKI in black over it and then put the Ninja Logo in Japanese (like on the 89'90 ZX7-H) in reflective black under that. then put the ZX6 logo red with a silver pin drop shade.
i went with white decals on my 07 black ninja. i liked the all black look for awhile but it started to get boring to me so i ended up pulling out all the stickers i had got with my parts and started putting them on, lol
i'll post pics up once i get a chance to take some new ones
i took the side decals and tail decals off. that way the white wouldn't really look out of place. i have my dynojet stickers on the tail where the 6r was and on the side fairings i have an attack kawasaki, and icon sticker. then on the lower cowl i have the Power Commander sticker and motosport sticker. pics are coming
