The clutch and bearings tend to expand as they heat up. So you need about .10 of play on the clutch bell when mounted on the motor shaft. Too little play and the bearings can become damaged. Too much play and the bearings can cause problems too.
Shimmimg the clutch refers to adding or removing shims on the bolt that holds the clutch bell on to get this play.
