Bought a baskecase 1980 midnight special for 250.00.Spent the winter getting it together.After alot of work its now (in my opinion) a good looking bike.I replaced the rusted out pipes with a nice 4 into 2 chrome set.#1 and #4 go to the right and #2 and #3 go to the left.Took it out of the garage today and fired it up outside for the first time.I am getting a "POP" out of #2 and 3. #1 and 4 are glowing orange.I dont know about these bikes but I do know this cant be good.I did a search but couldnt find anything specificallly about this problem.Any help would be greatly appreciated.

That would be a sign of being very lean on those two cylinders.
Probably carb related.
Although one set of coils fires 1 and 4 and the other fires 2 and 3, but I doubt that is your problem since they obviously fire.
I would start by trying to adjust the idle air screws on 1 and 4 out, but I bet the problem is in the carbs. Like clogged jets or passages or low float levels.80 SG XS1100

Take care of those pipes! If they are the Jardine spaghetti pipes, they are one of the more valuable sets of aftermarket pipes for these bikes.
Popping is usually due to fuel/air mixture screws. There is a tech tip about adjusting by ear vs using a colortune plug. Not sure on the glowing pipes though... They definitely shouldn't do that!

Those two are way too lean. You need to adjust your carbs. Other threads will show the way. Do a search.

WOW! That definitely doesn't sound good. What do your spark plugs look like? I don't know if a restriction in the pipe could cause that, but it might be worth checking as the problem seems isolated to one exhaust. Mice like to climb up and build nests in places like that. JATI think I have a loose screw behind the handlebars.

Wow sounds link a melt down is on its way if you let it run like that for very long. Like others said, take your plugs out and try to read the color, white is lean and would make the exhaust hotter than a rich condition (black plug). You should eat, sleep, breath in the carb maintenance section for a little while as I think you need to pull your carbs off and go through them again. GL
