I guess my rear exhaust headers are not supposed to glow, but they were yesterday.
The plugs do not show signs of running particularly lean but there is some heat getting back there from somewhere.
Currently the carbs are off for a full rebuild, and the front exhaust headers too, to get at the starter. I noticed that one of the headers was very loose in the collector, and this would probably be contributing to the "spitting" back through #1 and #4 carbs. I suspect the butterfly valve seals aren't helping much, the intake boots seem to be sound.
Anyway ... I was wondering if anyone else had experienced this. I do know that some exhaust headers, on some bikes do have a "glowing" issue, but I didn't think that the Venture Royale had this ... er ... feature.
Any thoughts?
