Inspection and cleaning

• Clean and inspect all parts carefully. If there
are any cracks or other defects replace the
damaged parts with new ones. Always use
original parts.
• Check the thickness of the clutch shoes by
using vernier callipers to measure the diameter
of the clutch. If the diameter is less than 60
mm the clutch assembly must be replaced (see
figure 16).
