NOTE:
The engine oil should be between the mini-
mum and maximum level marks.
4. If the engine oil is below the minimum
level mark, add sufficient oil of the recom-
mended type to raise it to the correct lev-
el.
NOTE:
When adding oil, be careful not to overfill the
engine; the oil level rises faster starting from
the half-level-portion on the dipstick.
5. Insert the dipstick into the oil filler hole,
and then tighten the oil filler cap.
CAUTION:
Make sure that the oil filler cap is securely
tightened, otherwise oil may seep out when
the engine is running.

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:

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.
