There's very little that can go wrong with the dry clutch to be honest, but the RS can wear one out pretty quickly. I would get the steel plates bead blasted (or try "roughing" them a little with some emery cloth) and fit some new clutch springs. The steel plates may however be past their best.

Make sure the steel plates are straight (if they are warped at all, then the clutch will slip) and make sure the fibre plates are free from any contamination. The pressure plate should also be checked to ensure it is straight. The RS clutch is very light, and prone to wear. You may find it's in need of complete replacement... basket, hub, pressure plate, springs, and fibre/steel plates, the lot!

An RS isn't really a bike to run on a tight budget, even an old one. It's still a GP bike, after all. The rings should be replaced after about 50 miles, pistons will need replacing every 200 miles or so, and the crank every 1000. The 1991 is probably the hardest on all the components too, by the nature of the way it makes its power. You'd possibly be better off with a well sorted NSR to begin with, but of course I have no idea of your background or experience so I'm probably talking crap... again!
