Probably something near a 175 main and a 42 slow. Those numbers change whether it's a California bike or an international bike. Could be anywhere from 160 to 175 and 40 or 42. Only real way to know is to open it up. Besides, unless you are the first owner, you have no idea what they could have thrown in there.

Edit: Oops, you said butterfly, not CV. I thought the '89s were the first year for the CV. No clue at all.
