51. 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
CAUTION:@ 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 indica-
tor light flickers or remains on, im-
mediately 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 suffi-
cient oil in the crankcase or the light
does not come on when pushing the
start switch, consult a Yamaha deal-
er. @6. After starting the engine, move the
starter (choke) halfway back.NOTE:@ For maximum engine life, never accel-
erate 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. @

6Installation
1. Measure the electrode gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.
2. Clean the gasket surface. Wipe off
any grime from the threads.
3. Install the spark plug and tighten it
to the specified torque.
NOTE:@ If a torque wrench is not available when
you are installing a spark plug, a good
estimate of the correct torque is 1/4 to
1/2 turn past finger tight. Have the
spark plug tightened to the specified
torque as soon as possible. @4. Install the spark plug caps.

1. Place the motorcycle on the cen-
terstand. Warm up the engine for
several minutes.NOTE:@ Be sure the motorcycle is positioned
straight up when checking the oil level.
A slight tilt toward the side can result in
false readings. @

6 10. Start the engine and warm it up for
several minutes. While warming
up, check for oil leakage. If oil
leakage is found, stop the engine
immediately and check for the
cause.
NOTE:@ After the engine is started, the oil level
indicator light should go off if oil is filled
to the specified level. @
