There is a small wave washer in the clutch that causes some wear on the inner most metal plate. This washer pushes the clutch stack out when you pull the lever. It will wear a groove into the closest metal plate.
Pull out all the plates. Swap the inner most metal plate with another one.
Also, the metal plates have sharp edges on one side and rounded on the other. When you reinstall all the metal plates, put the rounded edges to the outside of the clutch pack.
This will improve way the clutch releases.
