LUBRICATING THE CHAIN
Lubricate the chain following these instructions.
CAUTION*: Never use grease to lubricate
the chain. Grease helps to accumulate
dust and mud, which act as abrasive
and help to rapidly wear out the chain,
the front and rear sprockets.

Disassembling and cleaning
When particularly dirty, remove and clean the chain be-
fore lubrication. Proceed 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), sprocket guard (2), clip (3), mas-
ter link (4) with its O-rings and chain (5).
To reassemble, reverse the above procedure, making
sure to correctly set the clip (3) and master link (4) as
well as the relevant O-rings.
2- Make sure that the chain is neither worn out nor dam-
aged. If the rollers or the links are damaged, replace
the chain by following the instructions given in the
Scheduled Maintenance Chart.
3- Ensure that the sprockets are not damaged.
4- Wash and clean the chain as described hereunder.
5- If the chain has been cut, reassemble it using the mas-
ter link.

6- Assemble the master link spring (3) by setting the
closed side facing the chain direction of rotation, as
shown below.
Note *: The master link is the most critical safety part
in the drive chain. Even if the master links are reus-
able when in good conditions, for safety purposes we
advise using a new master link when reassembling
the chain.
7- Accurately adjust the chain as described in the relevant
paragraph.
