Keirin gears are usually close to what you use for a 200 (motor gets you up to speed), and kilo depends on your philosophy and physiology.

I've been creeping up over the years. Used to 200 in 94 at the biggest, rounds in 90, 92, kilo in 92, 94 or 96 depending upon track and weather conditions. These days I've been experimenting over 100 for 200, but still hovering around 95-100 for 200, 94ish for rounds. Kilo has lately been 97. All this does not mean I'm going faster (sadly).

This is a very personal topic, and perhaps more than any other, your mileage may vary. Also depends a lot of the level of your competition. If you're just getting started, sprinting in 86 or 88 may make total sense.
