Underdrive pulleys will be a smaller diameter than stock. If someone else doesn't beat me to it I'll measure my old stock ones and post tomorrow.

All you really have to do is look at the crank pulley. It will look like a big soup bowl. If you have underdrives, then the crank will be quite small, measuring about 3 inches across.
