DRIVE CHAIN SLACK INSPECTION AND ADJUSTMENT
3-35

NOTE:
If bleeing proves difficult, it may be necessary to
allow the brake fluid system to stabilise for a few
hours. Repeat the bleeding procedure when the
tiny bubbles in the system have disappeared.
j. Top up fluid to the maximum level.
DRIVE CHAIN SLACK INSPECTION AND
ADJUSTMENT
Inspecting slack:
NOTE:
Before checking and/or adjusting the chain, rotate
the rear wheel through several revolutions and
check the slack several times to find the point on
the wheel where chain slack is highest.
Check and/or adjust chain slack with rear wheel in
this “tight chain” position.
Drive chain slack:
30 ~ 40 mm
NOTE:
To check chain slack, the motorcycle must stand
in an upright position with its two wheels touching
the ground and no one sitting on it. Check slack in
the position shown in the figure.
2. Adjust:
•Drive chain slack
Slack adjustment:
Too little chain slack will overload the engine
and other vital parts. Keep the slack within the
specified limits.
CAUTION: 1. Check:
•Drive chain slack (a)
Out of specification ➔Adjust.

Rear wheel axle nut:
115 Nm (11.5 mkg)
•Turn each adjusting bolt exactly the same
amount to maintain correct axle alignment.
There are marks on each side of the
swingarm. Use these marks to align the rear
wheel.
DRIVE CHAIN LUBRICATION
The chain consists of many parts which work with
each other. If the chain is not maintained properly,
it will wear out quickly. Therefore, the chain must
be serviced regularly. This service is especially
necessary when riding in dusty areas. This motor-
cycle has a drive chain with small rubber O-Rings
between the chain plates. Steam cleaning, high-
pressure washing and certain solvents can dam-
age these O-Rings. Use only kerosene to clean
the drive chain. Wipe it dry, and thoroughly lubri-
cate it with SAE 80 ~ 90W motor oil or special lu-
bricant for O-Ring chains. Do not use any other lu-
bricants on the drive chain. They may contain sol-
vents that could damage the O-Rings.
Recommended lubricant:
SAE 80W/90 engine oil or
special lubricant for
O-Ring chains.
(1) O-Rings
•Loosen the axle nut (1).
•Loosen the locknuts (2) on each side. To tight-
en the chain, turn the chain adjusting bolts (3)
in direction (a). Loosen the locknuts on each
side. To loosen the chain, turn the chain
adjusting bolts in direction (b) and push the
wheel forward.
•After adjusting, tighten the locknuts (2). Then
tighten the axle nut (1) to the specified torque.
