If you're putting your weight to the outside of the turn, then not enough weight is going on the front wheel, which is what caused it to chatter. You want to apply weight to your outside/down leg AND the inside handlebar, preferably the drops if you're taking a turn at speed, as that lowers your center of gravity. The outside leg pressure keeps the rear tire from slipping, the inside handlebar pressure keeps the front from slipping. If you do these two things you shouldn't really need to think about which way you're leaning your body as you'll naturally lean correctly if you do both.
