Coolant
Check the coolant level in the reservoir tank when
the engine is cold. (The coolant level will vary with
engine temperature.) The coolant level is satisfac-
tory if it is between the “FULL” and “LOW” marks
on the tank. If the coolant level is at or below the
“LOW” level, add tap water (soft water) to bring the
level up to “FULL”. Change the coolant every two
years. (See pages 8-55 ~ 8-65 for details.)CAUTION:_ Hard water or salt water is harmful to the en-
gine. You may use distilled water if you can’t
get soft water. _

Cable inspection and lubrication
WARNING
Inspect cables frequently and replace if dam-
aged. Corrosion can result when the outer cov-
ering 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.
Recommended lubricant:

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