GEARSHIFT FORK TO GROOVE CLEARANCE
Using a thickness gauge, check the shifting fork clearance in the
groove of its gear.
The clearance for each of the three shifting forks plays an impor-
tant 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.
