Glowing header

My left side header tube is glowing cherry red after the engine runs for less than 2 minutes.Does anyone have any idea what could cause this problem. I have a stage 1 Hahn kit on an '04 busa.
 
if at idle lean yes but running lean at the idle wont hurt much (if not under load) but it sounds as you need to adjust the trim on that cylinder if its through a power commander
 
did you change the timming? do a quick compression check to make sure the valves are all ok... swap injectors and see if that changes anything...
 
Every 6 months or so I run a little techron fuel injection cleaner through my system. I have never had injector problems.
