Just road the bike back down to the barn in the dark... are exhaust headers supposed to glow? More specific, the right header side. Note that in my first set of pics in my introduction in the "Chit Chat" forum that, that is the side that one of the exhaust nuts isn't fully threaded on (I suppose I should take my special fancy new exhaust nut wrench to it to see if it's loose).
Perhaps while in storage a colony of gloworms has taken up residence?

No, the header pipes should not be glowing. Without further investigation, you really won't know for sure if the right side is running too rich or to lean. Either way, it's not good. Have you set the valve lash yet? Incorrect clearance can cause problems. Set exhaust at 0.008". Take a look at the condition of both sparkle plugs. Compare. And there is also the concern of exhaust valve recession...
About that partially unscrewed header nut. It may just not be screwed down all the way or it could be the curse of the buggered threads on the cylinder head exhaust spigot. Do not get overly aggressive with the exhaust nut wrench, aka: the Fugawee War Club. If the nut will not come off easily, you will need to saw it off to save the spigot threads and an expensive repair. One of the annual Airhead maintenance chores is to remove both exhaust nuts and apply a fresh smear of anti-seize compound.
IMHO, it may be time to do a full service on the bike; lubricants, spline lube at clutch and final drive, engine, carburetion, new tires... Catch the deferred maintenance issues before they catch you out.
