You can't catch it the first time you encounter it, but you can after you obtain Reshiram, later on. That's the trigger for Kyurem to return to its cave. Just do the usual - knock its HP down and either paralyse it or put it to sleep, then hit it with Dusk Balls.
Go to the the caves deepest part in the giant chasm
He is found in the Giant Chasm, close to Lacunosa City
Catch Kyurem, get the dna splicer. Trade to get a zekrom from someone that has white or white 2. then use the dna splicer
Go to Drakebreath then go up past the Team Steam HQ and there should be some land on the left. There is a path up the beach follow that all the way and there he is
