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.

How do u sychronize carbs on a 1980 midnight special


This is a difficult process for a trained mechanic requiring special tools and equipment. Your carbs may require overhaul before they can be properly adjusted to operate your 32 year old Classic motorcycle. I think it will be a good investment.

Please see your local Yamaha shop for repairs and adjustments.

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

Need to know how to sink my carbs and adjust them on a 1980 yamaha xs 650


Do you have a synchronizing tool? If not, you'll need one, either homemade or store bought. All what synching the carbs means is that they are both pulling in the same amount of gas and air based on manifold vacuum pressure.
