INSTRUMENT AND CONTROL FUNCTIONS
EAU13441
Catalytic converterThis vehicle is equipped with catalytic
converters in the exhaust system.
EWA10860
wThe exhaust system is hot after op-
eration. Make sure that the exhaust
system has cooled down before do-
ing any maintenance work.
ECA10700
cCThe following precautions must be
observed to prevent a fire hazard or
other damages.● ●● ●
●
Use only unleaded gasoline. The
use of leaded gasoline will cause
unrepairable damage to the
catalytic converter.
● ●● ●
●
Never park the vehicle near pos-
sible fire hazards such as grass
or other materials that easily
burn.
● ●● ●
●
Do not allow the engine to idle
too long.

w● ●● ●
●
Become thoroughly familiar with
all operating controls and their
functions before riding. Consult
a Yamaha dealer regarding any
control or function that you do
not thoroughly understand.
● ●● ●
●
Never start the engine or oper-
ate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of con-
sciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.
● ●● ●
●
For safety, always start the en-
gine with the centerstand down.

cCSee page 5-3 for engine break-in in-
structions prior to operating the ve-
hicle for the first time.1. Turn the key to “ON”.
ECAT1070
cCThe engine trouble warning light and
coolant temperature warning light
should come on for a few seconds,
then go off. If these warning lights
do not go off, have a Yamaha dealer
check their electrical circuits.2. Close the throttle completely.
3. Start the engine by pushing the
start switch while applying the front
or rear brake.NOTE:
If the engine does not start, release the
start switch, wait a few seconds, and
then try again. Each starting attempt
should be as short as possible to pre-serve the battery. Do not crank the en-
gine more than 5 seconds on any one
attempt. If the engine does not start with
the starter motor, try using the
kickstarter.

cCFor maximum engine life, never ac-
celerate hard when the engine is
cold!

Checking the spark plugThe spark plug is an important engine
component, which is easy to check.
Since heat and deposits will cause any
spark plug to slowly erode, the spark
plug should be removed and checked
in accordance with the periodic main-
tenance and lubrication chart. In addi-
tion, the condition of the spark plug can
reveal the condition of the engine.
To remove the spark plug
1. Remove panel A. (See page 6-5.)
2. Remove the spark plug cap.ZAUM00**

3. Remove the spark plug as shown,
with a spark plug wrench available
at a Yamaha dealer.
To check the spark plug
1. Check that the porcelain insulator
around the center electrode of the
spark plug is a medium-to-light tan
(the ideal color when the vehicle is
ridden normally).
NOTE:
If the spark plug shows a distinctly dif-
ferent color, the engine could be oper-
ating improperly. Do not attempt to di-
agnose such problems yourself. In-
stead, have a Yamaha dealer check the
vehicle.2. Check the spark plug for electrode
erosion and excessive carbon or
other deposits, and replace it if
necessary.Specified spark plug:

To install the spark plug
1. Measure the spark plug gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifi-
cation.Spark plug gap:
0.7 ~ 0.8 mm (0.028 ~ 0.031 in)2. Clean the surface of the spark plug
gasket and its mating surface, and
then wipe off any grime from the
spark plug threads.
3. Install the spark plug with the spark
plug wrench, and then tighten it to
the specified torque.Tightening torque:
Spark plug:
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 specified
torque as soon as possible.
4. Install the spark plug cap.
5. Install the panel.

Engine oil and oil strainerThe engine oil level should be checked
before each ride. In addition, the oil must
be changed and the oil strainer cleaned
at the intervals specified in the periodic
maintenance and lubrication chart.
To check the engine oil level
1. Place the vehicle on the
centerstand.NOTE:
Make sure that the vehicle is positioned
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 sev-
eral minutes, and then turn it off. Engine oil

To check the coolant level
The coolant level should be checked as
follows before each ride. In addition, the
coolant must be changed at the inter-
vals specified in the periodic mainte-
nance and lubrication chart.
1. Place the vehicle on the
centerstand.NOTE:●
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
●
Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
2. Check the coolant level in the cool-
ant reservoir.
