CAUTION:_ If the fuel level warning light comes
on, check the fuel level, and, if nec-
essary, refuel as soon as possible. _3. Shift the transmission into the neu-
tral position.
NOTE:_ When the transmission is in the neutral

CAUTION:_ The engine trouble warning light
should come on when the start
switch is pushed, and it should go
off when the start switch is released.
If the engine trouble warning does
not come on when pushing the start
switch, or it remains on after start-
ing, have a Yamaha dealer check the
self-diagnosis device. _6. After starting the engine, move the
starter (choke) knob back halfway.
ECA00045
CAUTION:_ For maximum engine life, never ac-
celerate hard when the engine is
cold! _7. When the engine is warm, turn the
starter (choke) off.NOTE:_ The engine is warm when it responds
normally to the throttle with the starter
(choke) turned off. _
EAU01258
Starting a warm engine Follow the same procedure as for start-
ing a cold engine with the exception
that the starter (choke) is not required
when the engine is warm.

Shifting Shifting gears lets you control the
amount of engine power available for
starting off, accelerating, climbing hills,
etc.
The gear positions are shown in the
illustration.NOTE:@ To shift the transmission into the neu-
tral position, press the shift pedal down
repeatedly until it reaches the end of its
travel, and then slightly raise it. @

EAU01880
Checking the spark plugs The spark plugs are important engine
components, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode,
they should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plugs can re-
veal the condition of the engine.
The porcelain insulator around the cen-
ter electrode of each spark plug should
be a medium-to-light tan (the ideal col-
or when the motorcycle is ridden nor-
mally), and all spark plugs installed in
the engine should have the same color.
If any spark plug shows a distinctly dif-
ferent color, the engine could be defec-
tive. Do not attempt to diagnose such
problems yourself. Instead, have a
Yamaha dealer check the motorcycle.
If a spark plug shows signs of electrode
erosion and excessive carbon or other
deposits, it should be replaced.Before installing a spark plug, the spark
plug gap should be measured with a
wire thickness gauge and, if necessary,
adjusted to specification.Clean the surface of the spark plug
gasket and its mating surface, and then
wipe off any grime from the spark plug
threads.
NOTE:@ If a torque wrench is not available when
installing a spark plug, a good estimate
of the correct torque is 1/4–1/2 turn
past finger tight. However, the spark
plug should be tightened to the speci-
fied torque as soon as possible. @
a. Spark plug gap
Specified spark plug:
DPR8EA-9 (NGK) or
X24EPR-U9 (DENSO)
Spark plug gap:
0.8–0.9 mm
Tightening torque:
Spark plug:
17.5 Nm (1.75 m·kgf)

Engine oil and oil filter
cartridge The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:Make sure that the motorcycle is posi-
tioned straight up when checking the oil
level. A slight tilt to the side can result in
a false reading. @2. Start the engine, warm it up for
several minutes, and then turn it
off.3. Wait a few minutes until the oil set-
tles, and then check the oil level
through the check window located
at the bottom-right side of the
crankcase.
NOTE:@ The engine oil should be between the
minimum and maximum level marks. @4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.To change the engine oil (with or
without oil filter cartridge replace-
ment)
1. Start the engine, warm it up for
several minutes, and then turn it
off.
2. Place an oil pan under the engine
to collect the used oil.1. Engine oil level check window
