SOURCE: 1980 Yamaha XS 1100 Carduretor diagram

It is part of a detent mechanism for the choke. No, all 4 carbs do not have them, only 1.
Here is a link to Yamaha's website, where you can pull up a diagram of your bike's carbs. The ball is #10 and there is also a spring with it.
http://www.yamaha-motor.com/sport/parts/home.aspx
They are saying there are 2 balls and 2 springs, but I do not remember them having 2. I also don't see another #10 or #11 on the picture anywhere. You should be able to look at the rod that connects all the chokes together and see if there are 2 sets of dimples for the balls. Obviously there will be one set in carb #1, if you find another set of dimples for a detent ball, then there indeed would be 2. Also, the carb body would be drilled for the spring and ball like the #1 carb is.
Thanks

WHY would I have oil in where my flywheel and coil


I haven't looked at a XS 1100 for many years, but my first guess is a leaking crankshaft oil seal. 1979 is a long time ago, 35 years to be exact, and if your bike is still running well, it deserves to have a leak here and there.
If the oil leak is not too much, keep an eye on the oil level in the engine and enjoy the ride, else you have to pull off the coil packs and flywheel (probably dry clutch assembly) to get to the oil seal. The best would be to have a bike shop look at it if it really bothers you.
Keep the air in your hair, your feet on the grass and the bears off your rear (view mirror). Oh yes, put a piece of rag on the floor under the engine when you park it!

I have a 1980 yamaha xs 1100 special, it sat in a garage for 3 years, i replaced the fuel lines, cleaned the tank, and replaced the plugs, how come it only idles when the choke is on and it sounds like a...


You probably have varnish build up in the carburetors, causing restricted air flow, and therefore the engine is running too lean, especially on the right side, and a lean running engine will run hot at the exhaust. It only idles when the choke is on because the choke creates a richer fuel supply. A can or two of commercial fuel cleaner through the fuel supply may get the engine's jet's orifices cleaned out. Otherwise, overhaul the carbs.
Hey, nice old bike, though. Good luck
