My 93 Classic used to die a lot at idle. The problem was the idle air bypass motor on the back of the intake plenum siezing up. I removed the 3 allen bolts holding it to the back of the plenum and sprayed it down with carb and choke cleaner. The motor has a small worm screw that pushes and pulls a little cone shaped piece in and out to control the amount of air going into the intake since the butterfly in the intake tube is closed at idle. The problem was that it wasn't opening up when I'd let off the throttle. After a few good spray downs I never had the problem again.
