Anyways, here's how I would think about it. When you get to the top, instead of coming straight down, you want to push away with a slight closing of the shoulders. As you get to the bottom, your arms will naturally bring you forward as they should be close to fully extended since you pushed out from the bar. As you start transferring the energy you have from the fall into horizontal motion, send your chest and upper body forward without sending your legs forwards. This should give your chest a good bit of forward movement. You'll get to the "front" of the pull-up and your body will start swinging back. As you move backwards, and this part can be tricky, you need to close your shoulders violently and use both your arms and core to transfer that momentum vertically.
As I said, it's really not easy to explain in text and even videos have their limitations. As you try to be more and more explosive on the pullups, you should be able to figure out the bottom part of the kip. To chain them together really comes down to a lot of feel and timing. I only figured them out a couple of weeks ago and I still lose the timing after a few of them.
The upside is that once you do figure it out, you can do pullups much faster and more efficiently since you're recycling much more energy from one rep to the next.
