INSPECTION
Check primary chain:
At the 500 mile (800 km) service interval.
At every 5000 mile (8000 km) service interval thereafter.
Check primary chain for correct tension by measuring its ver-
tical freeplay through the primary chain inspection cover
opening located near the top of the primary cover.
1. See Figure 1-24. Remove two screws from primary chain
inspection cover.
2. Remove primary chain inspection cover.
3. See Figure 1-25. Check primary chain tension by mea-
suring vertical freeplay (measuring midway between
sprockets) several times, each time with primary chain
moved (by rotating engine) to a different position on
sprockets.
4. Check primary chain tension against
sary, adjust as described below.

Hot (normal running temperature)
5. Install primary chain inspection cover. Tighten screws to
40-60 in-lbs (4.5-6.8 Nm).
ADJUSTMENT
1. See Figure 1-26. Loosen locknut and turn adjusting
screw:
a. Turn clockwise (inward) to reduce freeplay.
b. Turn counterclockwise (outward) to increase free-
play.
2. Tighten locknut to 20-25 ft-lbs (27.1-33.9 Nm).
