9Owners are personally responsible for their vehicle’s condition. Your motorcycle/scooter’s vital functions can start to
deteriorate quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements). Any dam-
age, fluid leak or loss of tire pressure could have serious consequences. Therefore, it is very important that, in addition
to a thorough visual inspection, you check the following points before each ride.

1. Turn the fuel cock to “ON”.
2. Turn the main switch to “ON” and
the engine stop switch to “#“.
3. Shift transmission into neutral.
NOTE:
When the transmission is in neutral,
the neutral indicator light should be
on. If the light does not come on, ask
a Yamaha dealer to inspect it.
4. Turn on the starter (choke) and
completely close the throttle grip.
5. Start the engine by pushing the
start switch.
NOTE:
If the engine fails to start, release the
start switch, wait a few seconds, then
try again. Each attempt should be as
short as possible to preserve the bat-
tery. Do not crank the engine more
than 10 seconds on any one attempt.
EC000034
cC
The oil level indicator light should
come on when the start switch is
pushed and should go off when
the start switch is released. If the
indicator light flickers or remains
on, immediately stop the engine
and check the engine oil level and
for oil leakage. If necessary, fill the
engine with oil and check to see
that the oil level indicator light
goes off. If the light does not go off
even with sufficient oil in the
crankcase or the light does not
come on when pushing the start
switch, consult a Yamaha dealer.
6. After starting the engine, move
the starter (choke) halfway back.
NOTE:
For maximum engine life, never
accelerate hard with a cold engine!
7. After the engine is warm, turn off
the starter (choke) completely.
NOTE:
The engine is warm when it responds
normally to the throttle with the starter
(choke) turned off.
