SOURCE: Need step by step how to synchronize carbs on 1982 yahama xj 1100
It doesn't really matter which make or model of bike it is, the procedure is exactly the same.
Firstly you will need a set of vacuum balance tubes - do you have those?
TRying to balance a 4 without is an exercise in futility. They are reasonably cheap for a home set.
Here is a step-by-step.

I had an XJ 1100 and had the same problem. after paying someone else two diferent times I found an article talking about the very problem, (wish I could tell you where it is but) what it said was this system was prone to moisture getting in the rear master cylinder. I took the cylider apart and carfully cleaned all the brown residue out of all the small areas and orfices. then with a large suction/pressure pump bought at NAPA I forced good quality dot 4 fluid through the lines untill all the fluid came out clear (better buy 2 quarts this may take several flushings. then disasemble and clean the wheel cylinder as carefully as you did the master cylinder. This solved the problem on my 82 XJ 1100, the article said the trick was that if you live in a climate where weather chages with the seasons changing the fluid each riding season should prevent this from clogging again. Hope this helps, mine worked great afterwords.

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.

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.
