I believe I had the same problem on my 04 600rr. It looks like the chrome/color is being rubbed off. If so, its caused by the foam insert located aroud the middle light. I ended up getting a new one and cutting off the foam around the light/windscreen section. I believe most of the new sportech screens come with a static plastic piece there now, but yours may have not. Contact them and see what they say. I tried a matching color sticker there for mine at first, but it just got bubbled with all the wind and looked like crap.
