10. Add sufficient oil of the recommended
type to raise it to the correct level, and
then install and tighten the oil tank filler
cap.
CAUTION:
In order to prevent clutch slippage (since
the engine oil also lubricates the clutch),
do not mix any chemical additives with
the oil or use oils of a higher grade than
“CD”. In addition, do not use oils labeled
“ENERGY CONSERVING II” or higher.
Make sure that no foreign material enters
the crankcase. Recommended engine oil:
See page 10-2.

Cable inspection and lubrication
WARNING
Inspect cables frequently and replace if dam-
aged. Corrosion can result when the outer
covering of control cables becomes damaged.
Cables can also become frayed or kinked. Op-
eration of controls could be restricted, which
could cause an accident or injury.
Lubricate the inner cables and the cable ends.
If the cables do not operate smoothly, ask a
Yamaha dealer to replace them.

CAUTION:
Be sure to use motor oils that do not contain anti-
friction modifiers. Passenger car motor oils (often
labeled “Energy Conserving”) contain anti-friction
additives which will cause clutch and/or starter
clutch slippage, resulting in reduced component
life and poor engine performance.
