I don't think that you could polish it out anyway as it likely has a clear coat over the polished/anodized aluminum. You'd have to take it down to bare metal and then it might darken later anyway.

I was just wondering if those Reed Valve covers had ever been removed on your bike such as during a valve adjustment/inspection. If the reed valve was not replaced properly or was leaking, it may be possible for hot exaust gasses to travel the wrong way and heat up the cover.
