AIR FUEL MIXTURE ERROR???
The screw on the black hose is the idle adj. if you look at my pictures page the last 3 are the bsr 42 carb and parts list.
Screw #19 adjusts the starter jet. Also here is a link to another picture that might help.

The glowing pipes (at night) are not out of the norm for newer engines. What is out of the norm is the popping you describe, that's a lean condition but the two symptoms would not be connected (as in a problem) in the Japenese bikes. These long time DS guys can weigh in but I wouldn't be concerned about the nighttime pipe thing.
