Here's a request for somebody who rides tonight or who has a garage since I won't be riding soon due to our snow and ice. The origin of this thread was simply wondering if the red headers are normal so:
After your ride, simply let the bike idle for a few minutes in the dark and see if your headers are dull red near where they come out of the engine. It seems to me that I've seen it on both of my Teneres but I can't swear to it.
If using a garage with the engine running and the door shut, unscrew the door bulb so you don't let the exhaust accumulate. Obviously, open the door right away, exhaust in confined spaces is deadly, you are responsible for you doing dumb things, your wife will get pissed if you stink up the house, yada, yada . . .
