Glowing exhaust..
I posted this a while back. Seems to fit here also.
That depends on the color. Bright cherry red or salmon and your literally playing with fire!!! A piston will start to get soft at a little over 1,500F (EGT). 1,600 and over, and you done.
Faint Red 930
Blood Red 1075
Dark Cherry 1175
Medium Cherry 1275
Cherry 1375
Bright Cherry 1450
Salmon 1550
Dark Orange 1630
You make the call at what color the pipe was. I set my EGT at 1,350 to 1,400F. I have run as high as 1,500 for a few seconds at a time but I don't recomend it; especially with a light racing piston. Lean is mean, but I see no sence in pushing it.

Glowing exhaust..
Update- thanks to a few members advice I messed with the air/fuel screw, while the machine was running at an idle in the dark. I waited for it to get bright red hot, and then adjusted the screw back/down a few turns. The red color started to dissapate, so I turned it all the way down to where it almost killed it. The "glowing" darn near went away totally. So I turned it back up a few times to get a good idle speed, not to much, but just enough. This seemed to reduce the glowing effect considerably. My only consensus is that it was getting to much fuel and burning it off was making the glow. Dont know exactly for sure, but it did help, and I no longer worry about it. Thanks to all!
