Shims are used between the upper bushing and the wire retaining ring. Guzzi uses a single thick shim in combination with zero or more thin shims. To adjust, you add thin shims until the wire retaining ring no longer fully seats. Then remove the last thin shim. Since the thin shims are fragile, I place them between the upper bushing and the thick shim. This prevents any damage from the wire retaining ring. The spare parts catalogs reference a number of shims with varying thicknesses:

• MG# 12527200: 2 mm (0.078 inch)
• MG# 12527201: 2.1 mm (0.082 inch)
• MG# 12527202: 2.2 mm (0.086 inch)
  MG# 12527301 is also listed as a part number for this shim
• MG# 12527203: 2.3 mm (0.09 inch)
• MG# 12527204: 2.4 mm (0.094 inch)
• MG# 12527210: 0.1 mm (0.0039 inch)

The inside diameter of these shims is 36 mm; the outside diameter is 42.85 mm.
