On a K1100 you need to take the brake lever off and lubricate where it pivots. This can be more difficult than one might expect.

The lever pivots on a small bolt. Part #5 in the following diagram. (The diagram is wrong. It goes through the brake lever from the bottom, not the top.)

http://www.realoem.com/bmw/enUS/showparts?id=0532-USA---89V2-BMW-K%201100%20RS%20(0522,0532)&diagId=32_0784

This bolt is held in by some rather sturdy thread locker so make sure that you use a good Allen wrench and that it is well seated in the bolt head or you can strip the head if you are not careful.

Once the bolt has cleared all of its threads the head is not exposed enough to grab it with pliers and it does not fall right out so it may take some work to get it out.

When was the last time the brake fluid was changed? The other possibility is crap in the piston return hole preventing the brake fluid from pushing the piston back. If the fluid is nice and brown and dirty, then that's a good bet. You'll need to pump all the old fluid out so you can see the bottom of the master cylinder. There are two holes in the casting: both should be clear.

Also: check that it isn't simply dirt around the brake pads preventing them from moving.

The next thing I would try is replacing Part #6 in the diagram I linked to above.
