Hi Im kind of new to the Forums here.
I have a '02 600f Sport and there is a small rust stain at the bottom middle of the headlight from something behind the light, Im wondering if anybody had this problem and what it is?
When it gets wet a rusty watermark appears.

 

Well, you'll have to find the steel part that is rusting, and sand and paint it!
Sounds like maybe a steel clip is rusting somewhere and the water is following the edge of the lamp.
I haven't heard much about it being a common problem, but maybe it is?

 

I think Ill try take the front fairing off soon to see what there is above the lights that could be rusting. Thought I'd ask here first.
