I have about 50 miles of current driving on the bike. I am running 91 octane gas. I just noticed that the back of the muffler seems to be getting very hot, to the point of discoloration. I have added some pictures to show what I mean. I don't think it ever looked that way before. Is this normal? If not, what might be causing it, and is it a bad thing, besides turning the exhaust blue? Thanks.
