I really like that green fade. But the paint does look a bit dinged up, and it is your bike (unless you want to sell it to me! and, um, make it smaller...). It would be pretty slick to replicate the decal. I'm guessing it's a lost cause trying to find a true replacement -- my "typical" Kabuki, had different decals.
Mine actually has a killer head badge:
Anything similar on this frame?
PS: That's a photo from when I first got the bike. It's still no diamond, but I'm not that bad to my ride.
