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

NOTE:
●If the engine fails to start, release the start
switch, then push the start switch again.
Pause a few seconds before the next at-
tempt. Each cranking should be as short
as possible to preserve battery energy. Do
not crank the engine more than 10 sec-
onds on each attempt.
●If the battery is discharged, pull the recoil
starter to start the engine.
7. If the engine is started with the starter
(choke) in position 1, the starter (choke)
should be returned to position 2 to warm
up the engine. If the engine is started with
the starter (choke) in position 2, keep the
starter (choke) in this position to warm up
the engine.
8. Continue warming up the engine until it
idles smoothly and return the starter
(choke) to position 3 before riding.
CAUTION:
See the “Engine break-in” section prior to op-
erating engine for the first time.

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.
