I'm writing this Friday from a campground and so it won't get sent
until Monday later.
I've whined about my Cobras bluing at the baffles before. Since the
bike seems to run well I decided that is just the way it is going to
be. How would I know if my jetting is off beside multiple dyno runs and
hundreds of dollars and hours in the carbs? Can't see it for a bike
that seems fine (to me).
BTW I rarely allow the bike more than 20 seconds of idle at start up so
I doubt that's it. Take off and go easy for a few miles, choke off
usually within 2 miles.
I do sit on the highway at 75mph during my commute.
If I ever repipe I will probably get Vance&Hines or something double
walled.
I have little bluing on the header, just a touch.

I'm curious if you know why that portion of your exhaust is

strange to me. I always thought that the farther from the head you

turning colors I would begin to wonder about the temps at the head.
That caught my eye too. These are both pretty wild leaps of intuition.
I
wonder what we are seeing is raw leftover fuel burning when it gets
close
enough to the end of the pipe to find additional air. Another (pretty
remote) possibility is that if he runs it a lot of the time at the
same RPM
and there is some sort of standing wave pattern getting etched on the
pipes.
I wonder how blue it got just outside the exhaust port?
