I think you got to way too rich to blue headers. Slightly lean bikes run much hotter than slightly rich bikes IE to get rid of the excessive deceleration popping. For example, if you compare two standard Bonnies, both with after market open pipes, AI removed, AF screws out to eliminate popping the one not re-jetted will blue to the second curve of the headers. The re-jetted bike will blue just passed the first curve. I guess we are saying the same thing, but I've never seen a rich Triumph with over bluing.
