Where to get the xsr or black Yamaha emblem?

Hi, I recently got a green xsr 700. I got the white Yamaha logo removed from the tank and would like to replace it with something else.. xsr or xsr 700, or brushed metal Yamaha logos would be nice. I called certified Yamaha retailers here in ?stanbul but they couldn't find them in the accessory or spare parts list.. they sent email for that.. but anyway the service guy told me that even they have xsr logo it will be the same size with one on the tank which I find very small..

So anybody knows where to get black or metallic xsr or Yamaha logos?

Thank you in advance for comments and advices
