Sorry Guys
Not ever have genuine honda exhaust systems gone blue with me.If its happened with you, you have problems not even running for hours in a garage has that happened.
That is why I hate Brit bikes cos they blue within minutes

Never happened on one of my bikes in my ownership, but I did buy a cb750a a while back (don't ask) where the original Honda exhausts had seriously blued through a very over-lean setup. Agree with Bitsa, it's pretty hard to get an OEM double skinned header to go...
