i build 400 arctic cat 400 motors all day. the reason the pipe is glowing red is that the motor is runing way lean when u r runing full throttle. ive got a fix for that. pm me for more info

 

What is the fix for my problem any help would be great thanks?

 

i thought glowing header pipes meant a rich condition, b/c the fuel is still burning after the exhaust valve has been opened and continues to burn through there. thats what happens to our cars, and ive always heard that.

 

what is the fix I'm having the same problem any help would be appreciated thanks
