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”

→
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:

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.
