STARTER CLUTCH
Install the starter driven gear onto the starter clutch and turn the
starter driven gear by hand (the gear turns in only one direction).
The starter driven gear should turn smoothly. If excessive resis-
tance is felt while turning the starter driven gear, inspect the

which contacts the starter clutch, for wear or damage. If any
wear or damage is found, replace the defective part(-s).

GEARSHIFT LINKAGE INSPECTION
GEARSHIFT SHAFT/GEARSHIFT ARM

Check the return spring on the gearshift arm for damage or
fatigue.
If any defects are found, replace the defective part(-s).
OIL SEAL INSPECTION
Inspect the gearshift shaft oil seal’s lip for damage or wear.
If any defects are found, replace the oil seal with a new one.
