I opened up the primary last night & everything looked pretty normal... except for the chunks of magnet stuck to all the steel parts inside! In the 20 minutes or so that it took me to tear this thing apart, I got to see that there were a few other improvements made when they went to the 5 speed in '91. It's a damn good thing too, because 'What the hell were they thinking?' keeps going through my head. Mainly, because (unlike the 5 speeds) you have to remove the entire primary cover if you ever want to change your clutch cable. Lame. Oh well, just proves to me that everyone has some learning to do sometimes.
