NOTE:
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is
1/4Ð1/2 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.

a.Spark plug gapTo install the spark plug
1.Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to
specification.
2.Clean the surface of the spark
plug gasket and its mating sur-
face, 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.

Transmission oilThe transmission oil level should be
checked before each ride. In addition,
the transmission oil must be changed
at the intervals specified in the peri-
odic maintenance and lubrication
chart.
To check the transmission oil level
1.Place the motorcycle on a level
surface and hold it in an upright
position. NOTE:
Make sure that the motorcycle 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
several minutes, and then turn it
off.

cC8In order to prevent clutch slip-
page (since the transmission
oil also lubricates the clutch),
do not mix any chemical addi-
tives with the oil.
8Make sure that no foreign
material enters the transmis-
sion.6.Start the engine, and then let it
idle for several minutes while
checking the transmission for oil
leakage. If oil is leaking, immedi-
ately turn off the engine and
check for the cause.

The coolant should be between the
minimum and maximum level marks.3.If the coolant is at or below the
minimum level mark, open the
reservoir cap, add coolant to the
maximum level mark, and then
close the reservoir cap.
EAU03761
CoolantTo check the coolant level
1.Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:
8The coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
8Make sure that the motorcycle is
positioned straight up when
checking the coolant level. A
slight tilt to the side can result in
a false reading.

Checking the brake fluid
levelInsufficient 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
brake fluid level may indicate worn
brake pads and/or brake system
leakage. If the brake level is low, be
sure to check the brake pads for
wear and the brake system for leak-
age.

8Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking perfor-
mance.
8Be 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.
8Brake fluid may deteriorate paint-
ed surfaces or plastic parts.
Always clean up spilled fluid
immediately.
8As 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.

make sure that the top of the

ing leakage and poor braking
performance.REARRecommended brake fluid:

Changing the brake fluidHave a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and lubrica-
tion chart. In addition, have the oil
seals of the master cylinder and
caliper as well as the brake hoses
replaced at the intervals listed below
or whenever they are damaged or
leaking.
8Oil seals: Replace every two
years.
8Brake hoses: Replace every four
years.

Drive chain slackThe drive chain slack should be
checked before each ride and adjust-
ed if necessary.
To check the drive chain slack
1.Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:
When checking and adjusting the
drive chain slack, the motorcycle
should be positioned straight up and
there should be no weight on it.
a
a.Drive chain slack2.Shift the transmission into the
neutral position.
3.Move the rear wheel by pushing
the motorcycle to locate the tight-
est portion of the drive chain,
and then measure the drive
chain slack as shown.
4.If the drive chain slack is incor-
rect, adjust it as follows. Drive chain slack:
25Ð40 mm

Checking and lubricating the
cablesThe operation of all control cables
and the condition of the cables
should be checked before each ride,
and the cables and cable ends
should be lubricated if necessary. If a
cable is damaged or does not move
smoothly, have a Yamaha dealer
check or replace it.
Recommended lubricant:
Engine oil
EW000112
wDamage to the outer sheath may
interfere with proper cable opera-
tion and will cause the inner cable
to rust. Replace a damaged cable
as soon as possible to prevent
unsafe conditions.
2.Wipe the drive chain dry.
3.Thoroughly lubricate the drive
chain with a special O-ring chain
lubricant.
ECA00052
cCDo not use engine oil or any other
lubricants for the drive chain, as
they may contain substances that
could damage the O-rings.

Checking and lubricating the
throttle grip and cableThe operation of the throttle grip and
the condition of the throttle cable
should be checked before each ride,
and the cable should be lubricated or
replaced if necessary.NOTE:
Since the throttle grip must be
removed to access the throttle cable
end, the throttle grip and the cable
should always be lubricated at the
same time.1.Remove the throttle grip by
removing the screws.
2.Disconnect the throttle cable,
hold it up, and then apply several
drops of oil to the cable end,
allowing it to trickle into the
sheath.
3.Connect the throttle cable, and
then grease the inside of the
throttle grip housing.4.Grease the metal-to-metal con-
tact surface of the throttle grip,
and then install the grip by
installing the screws.
Recommended lubricant:
Throttle cable:
Engine oil
Throttle grip housing and grip:
Lithium-soap-based grease
(all-purpose grease)

Adjusting the Autolube
pumpThe Autolube pump is a vital and
sophisticated component of the
engine, which must be adjusted by a
Yamaha dealer at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
