Although we haven't talked about it in some time, yes, the right cylinder on these motors does run a little hotter than the left one, but it's not an issue usually, and not as bad on the '77 and older bikes. In '78, when the E.P.A. started mandating the carbs, it got worse. But still, that pipe glowing red isn't right, you're too lean. I'd step the pilots up some more.
I have a '78 and an '83, both of which would be more prone to doing this, and neither one does.
