breakage. If the drive chain slack is more

the frame, swingarm, and other parts. To pre-
vent this from occurring, keep the drive
chain slack within the specified limits.

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
0 -rings between each side plate. Steam clean-
ing, high-pressure washing, certain solvents,
and the use of a coarse brush can damage
these 0 -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 0-ring chains.
Do not use any other lubricants on the drive
chain since they may contain solvents that could
damage the 0 -rings.
