I'm wondering the same question myself. I have no clutch pressure or return at the lever. so i took off the clutch cover and decided to take out the clutch springs. But before I did I noticed that the springs were pretty compressed because the bolts were tight. When I go to put them back in i have no clue how tight to make them!! just tightin them until there isn't any more thread left? I'm clueless here......clymer manual is no help.
