I totally agree with everyone else comments, however; they set these bikes up very "lean" from the factory so they will meet EPA specs and that makes them run hot which is what causes the discoloration. I don't know if "richening" up the fuel mixture will stop the bike from getting hot enough to "blue" the pipes but it can't hurt to try as long as a skilled mechanic is doing the adjusting for you. But other than changing the color of your pipes, I don't remember ever hearing of a real problem associated with the way they come set from the factory.
