Engine trouble warning light“”
This warning light comes on if a prob-
lem is detected in the electrical circuit
monitoring the engine. If this occurs,
have a Yamaha dealer check the self-
diagnosis system.
The electrical circuit of the warning light
can be checked by turning the key
to“”. The warning light should come
on for a few seconds, and then go off.
If the warning light does not come on
initially when the key is turned to“”,
or if the warning light remains on, have
a Yamaha dealer check the electrical
circuit.
EAU11591
Speedometer UK ONLY
The speedometer shows the riding
speed.
EAUM1471
Fuel gauge The fuel gauge indicates the amount of
fuel in the fuel tank. The needle moves
towards “E” (Empty) as the fuel level
decreases. When the remaining fuel in
the tank reaches approximately 2.7 L
(0.72 US gal, 0.60 Imp.gal), the fuel
level warning light will come on and the
multi-function display will automatically
change to the “Trip/fuel” mode. (See
page 3-4.) If this occurs, refuel as soon
as possible.TIPDo not allow the fuel tank to empty itself
completely.

Ignition circuit cut-off system The ignition circuit cut-off system (com-
prising the sidestand switch and brake
light switches) has the following func-
tions.

It prevents starting when the side-
stand is up, but neither brake is ap-
plied.


It prevents starting when either
brake is applied, but the sidestand
is still down.


It cuts the running engine when the
sidestand is moved down.
Periodically check the operation of the
ignition circuit cut-off system according
to the following procedure.

1. Connect the headlight coupler and
the turn signal couplers.
2. Place the cowling in the original
position, and then install the
screws.

EAU19622
Checking the spark plug The spark plug is an important engine
component, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode, it
should be removed and checked in ac-
cordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plug can re-
veal the condition of the engine.
The porcelain insulator around the cen-
ter electrode of the spark plug should
be a medium-to-light tan (the ideal color
when the vehicle is ridden normally). If
the spark plug shows a distinctly differ-
ent color, the engine could be operating
improperly. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the vehicle.
If the spark plug shows signs of elec-
trode erosion and excessive carbon or
other deposits, it should be replaced.

6 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.
TIPIf 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.
EAUM1551
Engine oil The engine oil level should be checked
before each ride. In addition, the oil
must be changed at the intervals spec-
ified in the periodic maintenance and
lubrication chart and when the service
indicator light comes on.
To check the engine oil level
1. Place the scooter on the center-
stand. 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, remove the oil filler cap, wipe
the dipstick clean, insert it back
into the oil filler hole (without
screwing it in), and then remove it
again to check the oil level.TIPThe engine oil should be between the
minimum and maximum level marks.

66. Refill with the specified amount of
the recommended final transmis-
sion oil, and then install and tighten
the oil filler cap. WARNING! Make
sure that no foreign material en-
ters the final transmission case.
Make sure that no oil gets on the
tire or wheel.
[EWA11311]
7. Check the final transmission case
for oil leakage. If oil is leaking,
check for the cause.
EAU20070
Coolant The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAUM2102
To check the coolant level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.TIP

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 through
the check window.TIPThe coolant should be between the
minimum and maximum level marks.
3. If the coolant is at or below the
minimum level mark, remove the
cowling A. (See page 6-6.)
4. Open the reservoir cap, and then
add coolant to the maximum level
mark. WARNING! Remove only
the coolant reservoir cap. Never
attempt to remove the radiator
cap when the engine is hot.
[EWA15161]
NOTICE: If coolant is not
available, use distilled water or
soft tap water instead. Do not
use hard water or salt water
since it is harmful to the engine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
