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.

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:
0.6–0.7 mm (0.024–0.028 in)

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.
Recommended transmission oil:

Insufficient brake fluid may allow air
to enter the brake system, possibly
causing it to become ineffective.
Before riding, check that the brake
fluid is above the minimum level mark
and replenish if necessary. A low bra-
ke fluid level may indicate worn brake
pads and/or brake system leakage. If
the brake fluid level is low, be sure to
check the brake pads for wear and
the brake system for leakage.
Observe these precautions:
●When checking the fluid level,
make sure that the top of the bra-
ke fluid reservoir is level.
●Use only the recommended qua-
lity brake fluid, otherwise the rub-
ber seals may deteriorate, cau-
sing leakage and poor braking
performance.
●Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performan-
ce.
●Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vapor
lock.
●Brake fluid may deteriorate pain-
ted surfaces or plastic parts.
Always clean up spilled fluid
immediately.
●As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if
the brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause.
EAU22731
Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the TIP after the periodic maintenan-
ce and lubrication chart. In addition,
have the oil seals of the master cylin-
ders and calipers as well as the brake
hoses replaced at the intervals listed
below or whenever they are damaged
or leaking.
●Oil seals: Replace every two
years.
●Brake hoses: Replace every four
years.
Recommended brake fluid:
