ADJUSTING THE DRIVE CHAIN SLACK
NOTE:
The drive chain slack must be checked at the
tightest point on the chain.
CAUTION:
ECA13550
A drive chain that is too tight will overload
the engine and other vital parts, and one that
is too loose can skip and damage the swing-
arm or cause an accident. Therefore, keep
the drive chain slack within the specified lim-
its.
1. Stand the vehicle on a level surface.
WARNING
EWA13120
Securely support the vehicle so that there is
no danger of it falling over.
NOTE:
Place the vehicle on a suitable stand so that the
rear wheel is elevated.
2. Spin the rear wheel several times and find the
tightest position of drive chain.
3. Check:
● Drive chain slack “a”
Out of specification → Adjust.
NOTE:
● Measure the drive chain slack in the intermedi-
ate position between drive axle center and rear
wheel axle center.
● If the chain contacts the drive chain guide, this
is the limit of chain slack.
4. Adjust:
● Drive chain slack

a. Loosen the wheel axle nut “1”.
b. Turn the drive chain adjusting plate “2” in di-
rection “a” or “b” until the specified drive chain
slack is obtained.
NOTE:
To maintain the proper wheel alignment, adjust
both sides evenly.
c. Tighten the wheel axle nut to specification.

LUBRICATING THE DRIVE CHAIN
The drive chain consists of many interacting
parts. If the drive chain is not maintained proper-
ly, it will wear out quickly. Therefore, the drive
chain should be serviced, especially when the
vehicle is used in dusty areas.
This vehicle has a drive chain with small rubber
O-rings between each side plate. Steam clean-
ing, high-pressure washing, certain solvents,
and the use of a coarse brush can damage
these O-rings. Therefore, use only kerosene to
clean the drive chain. Wipe the drive chain dry
and thoroughly lubricate it with engine oil or
chain lubricant that is suitable for O-ring chains.
Do not use any other lubricants on the drive
chain since they may contain solvents that could
damage the O-rings.
