Check the pinion damages or wear and replace it should the
wear degree be as the one shown in figure.
Remove the wheel and check the wear of the rear sproket
teeth. The below figure shows the outline of teeth in normal
and excessive wear. Should the sprocket be badly worn out, re-
place it by loosening the six fastening screws to the hub.
WARNING*: Misalignment of the wheel will
result in abnormal wear and may result in
an unsafe riding condition.
Note*: In muddy and wet conditions, mud
sticks to the chain and sprockets resulting in
an overtight chain. The pinion, the chain,
and the rear sprocket wheel wear increases
when running on muddy ground.
Excessive consumption

LUBRICATING THE CHAIN

Lubricate the chain following these instructions.
WARNING * : Never use grease to lubricate
the chain. Grease helps to accumulate dust
and mud, which act as abrasive and hepl to
rapidly wear out the chain, the sprocket,
and the crown.

Disassembling and cleaning

When particularly dirty, remove and clean the chain before lu-
brication.
Work as follows:
1 - Set a stand or a block under the engine and see that the
rear wheel is lifted from the ground.
Remove: screws (1), transmission sprocket guard (2), clip
(3), master link (4) and transmission chain (5);
To reassemble, reverse the above procedure.
