Oil level warning light “ ”
This warning light comes on when the
key is in the “ ” position or if the oil
level in the 2-stroke engine oil tank is
low during operation. If the warning
light comes on during operation, stop
immediately and fill the oil tank with
2-stroke engine oil of either JASO
grade “FC” or ISO grades “EG-C” or
“EG-D”. The warning light should go
off after the 2-stroke engine oil tank
has been refilled.
TIP
If the warning light does not come on
when the key is in the “ ” position or
does not go off after the 2-stroke
engine oil tank has been refilled, have
an Yamaha dealer check the electrical
circuit.

Do not operate the vehicle until you
know that the engine oil level is suf-
ficient.

Tips for reducing fuel con-
sumption
Fuel consumption depends largely on
your riding style. Consider the follo-
wing tips to reduce fuel consumption:
●Turn the starter (choke) off as
soon as possible.
●Shift up swiftly, and avoid high
engine speeds during accelera-
tion.
●Do not rev the engine while shif-
ting down, and avoid high engine
speeds with no load on the engi-
ne.
●Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at
traffic lights or at railroad cros-
sings).
EAU16830
Engine break-in
There is never a more important
period in the life of your engine than
the period between 0 and 1000 km
(600 mi). For this reason, you should
read the following material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1000 km (600 mi). The various parts in
the engine wear and polish themsel-
ves to the correct operating clearan-
ces. During this period, prolonged
full-throttle operation or any condition
that might result in engine overhea-
ting must be avoided.
EAUS1560
0–500 km (0–300 mi)
●Avoid prolonged operation above
4000 r/min.
●After every hour of operation,
stop the engine, and then let it
cool for five to ten minutes.
●Vary the engine speed from time
to time. Do not operate the engi-
ne at one set throttle position.500–1000 km (300–600 mi)
●Avoid prolonged operation above
6000 r/min.
●Rev the engine freely through the
gears, but do not use full throttle
at any time. NOTICE:After 1000
km (600 mi) of operation, the
transmission oil must be chan-
ged.
[ECA10370]
1000 km (600 mi) and beyond
●The vehicle can now be operated
normally.
ECA10310
●Keep the engine speed out of
the tachometer red zone.
●If any engine trouble should
occur during the engine break-
in period, immediately have a
Yamaha dealer check the vehi-
cle.

Instead, have a Yamaha dealer check
the vehicle.
2. Check the spark plug for electro-
de erosion and excessive carbon
or other deposits, and replace it if
necessary.
To install the spark plug
1. Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to spe-
cification.
1. Spark plug gap
2. Clean the surface of the spark
plug gasket and its mating surfa-
ce, 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.
TIP
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. Howe-
ver, the spark plug should be tighte-
ned to the specified torque as soon
as possible.
4. Install the spark plug cap.
5. Install the panel.
EAUS1591
Transmission oil
The transmission oil level should be
checked before each ride. In addition,
the oil must be changed at the inter-
vals specified in the periodic mainte-
nance and lubrication chart.
To check the transmission oil level
1. Oil filler cap
2. Oil check bolt
1. Remove cowling A. (See page
6-8).
2. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion.
Tightening torque:
Spark plug:
22.5 Nm (2.2 m•kgf, 16.3 ft•lbf)
Spark plug gap:

TIP
Make sure that the vehicle is positio-
ned straight up when checking the oil
level. A slight tilt to the side can result
in a false reading.
3. Remove the oil check bolt, and
then check the oil level.
TIP
The oil should be at the brim of the
check hole.
4. If the oil is below the brim of the
check hole, remove the oil filler
cap, add sufficient oil of the
recommended type to raise it to
the correct level, and then install
the oil filler cap.
5. Install the oil check bolt, and then
tighten it to the specified torque.To change the transmission oil
1. Oil check bolt
2. Transmission oil drain bolt
3. Washer
1. Place an oil pan under the trans-
mission oil case to collect the
used oil.
2. Remove the drain bolt and the oil
check bolt to drain the oil.
3. Install the drain bolt and the
check bolt, and then tighten them
to the specified torques.4. Remove the oil filler cap, refill
with the specified amount of the
recommended transmission oil,
and then install and tighten the oil
filler cap. NOTICE: Make sure
that no foreign material enters
the transmission case.
[ECAM1021]
5. Start the engine and let it idle for
several minutes while checking
the transmission oil case for oil
leakage. If oil is leaking, imme-
diately turn the engine off and
check for the cause.
