In addition to my previous thread about idle problem, the rear header pipe glows red hot after running a while. I'm running open headers at this time.

Any ideas?

 

It's Normal..Rotary exhaust Temps are Hotter than Piston engines.I have a Full set-up on my N/A,And I can get the Header Cherry Red,just "hot-footin it" around Town!

 

no actually it's not normal. If it's just the rear pipe getting red hot you're lean on the rear rotor, or there is a sevear timming issue just on the rear rotor. Don't know how that might happent though

 

Not normal at all. Either a fuel mixture issue, or a timing/ignition issue...

 

glowing in itself happens, and i'm not going to touch the "normal vs abnormal" argument. suffice it to say that even with a spot-on tune, i've seen some glow with really hard, sustained runs. however, it does sound like your rear is leaner than it should be, so i would look into your carbie.
