GEAR-SHIFTING FORK
Using a thickness gauge, check the clearance between
the groove of its gear and shifting fork.
The clearance for each of the three shifting forks plays
an important role in the smoothness and positiveness of
shifting action.
If the clearance checked is noted to exceed the limit
specified, replace the fork or its gear, or both.
