Thats from not drying your bike after you wash it. take a small electric sander to it (not to much or you will wear a hole in it) then polish it and that will give it a seal that is good for a while. alot cheaper than going out and buying a new header. We did this to my brothers procircuit pipe that he had on his Cr 85 that had sat in out garage for a little over a year and it looks brand new now.
