DRIVE CHAIN SLACK INSPECTION AND ADJUSTMENT/
DRIVE CHAIN LUBRICATION

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.

REAR SHOCK ABSORBER ADJUSTMENT
3-39
NOTE:
•Use the special wrench included in the
owner's tool kit to make the adjustment.
•The spring preload setting is determined by
measuring distance A, shown in the illustra-
tion. The longer distance A is, the lower the
spring preload; the shorter distance A is, the
higher the spring preload. With each com-
plete turn of the adjusting nut, distance A
changes by 1.5 mm.
Spring preload:
Minimum (soft):
Distance A = 217 mm
Standard:
Distance A = 211 mm
Maximum (hard):
Distance A = 205 mm
2. Tighten the locknut to the specified torque.
Always tighten the locknut against the adjust-
ing nut, and then tighten the locknut to the
specified torque.
CAUTION:Locknut:
45 Nm (4.5 m·kgf)
