Routine maintenance operations
CAUTION
Danger of falling or turning over.
As soon as the motorcycle is stood up, i.e. moved
from the park position to the riding position, the
stand retracts automatically.
Keep the motorcycle in the vertical position with both
wheels on the ground.
NOTE
If you attempt to check the oil with the motor-
cycle leaned in either direction from the vertical, your
measurement will be inaccurate.
Visually check to ensure that the oil level is at or
above the lower edge of the threaded hole (3).
If it is:
Inspect the gasket (2). Replace if damaged.
Install and tighten the screw (1).
If it is not:
Top up the oil per the following paragraph.
TOPPING UP
If it is necessary to top up the transmission:
Unscrew and remove the filler cap (4).
Pour a small quantity of oil and wait about one minute
to allow the oil to flow into the transmission.
Check the oil level as described above.
Repeat this operation until the oil level is at or slightly
above the edge of the threaded hole (3). Follow the
screw installation instructions above.
WARNING
Tighten the filler screw snugly, to ensure that it
does not leak. Regularly check the transmission
cover gasket to ensure that it is not leaking.
Never ride the motorcycle with low transmission
oil or with contaminated or unapproved lubri-
cants. This will greatly accelerate the wear of
moving parts, and cause irreparable failure.
It also could lead to a seizure, with subsequent
crash and serious injury, or even death.
