If you search past posts on "glowing headpipe" you will probably find that most people say it is normal with the stainless steel yosh system. Unless your quad is idling rough or popping and farting upon decelleration, you probably don't need to adjust your idle midture screw. I assume the glowing is only really visible when it gets dark outside? If it glows bright red doring the daytime, then your idle is too lean. My quad does the same thing. Good luck!

YES THE INTAKES WERE TIGHT
THE SPECTS SAID 0.10 TO 0.15 FOR INTAKE
0.15 TO 0.20 EXHAUST ON A COPY OF THE SERVICE MANUAL FROM BIG VALLEY ATV CLUB ONLINE
IT WAS A NIGHT & THE HEADPIPE SEEMED TO GLOW EVEN WHILE HOLDING AT ABOUT 2500 RPM
I DO HEAR SLIGHT VALVETRAIN NOISE

Those specs are all in MM, The specs out f the factory service manual are,
Intake~0.10~0.15mm (0.0039~0.0059in) I set my intakes closer to the 0.0059 becaues they seem to tighten up by the next valve adjustment
Exhaust~0.15~0.20mm (0.0059~0.0079in) I also do the exhausts closer to the 0.0059 because they don't tighten up like the intakes do
