Lubrication (oil injection models)

1. Install the spark plug(s) and torque to
proper specification. For information on
spark plug installation, see page 73.
2. Fill the oil tanks. This prevents the for-
mation of condensation. For models with
a remote oil tank, it may be necessary to
manually override the control unit to
completely fill the engine oil tank.
3. Change the gear oil. For instructions,
see page 77. Inspect the oil for the pres-
ence of water which indicates a leaky
seal. Seal replacement should be per-
formed by an authorized Yamaha dealer
prior to use.
4. Grease all grease fittings. For further de-
tails, see page 72.
TIP:
For long-term storage, fogging the engine
with oil is recommended. Contact your
Yamaha dealer for information about fogging
oil and procedures for your engine.
