Spark plugsRemoval
1. Remove the rear right and front
left cylinder head covers by pulling
them outward as shown.
2. Remove the spark plug caps.
3. Use the spark plug wrench in the
tool kit to remove the spark plugs
as shown.Inspection
The spark plug is an important engine
component and is easy to inspect. The
condition of the spark plug can indicate
the condition of the engine.
Normally, all spark plugs from the
same engine should have the same
color on the white insulator around the
center electrode. The ideal color at this
point is a medium-to-light tan color for a
motorcycle that is being ridden normal-
ly. If one spark plug shows a distinctly
different color, there could be some-
thing wrong with the engine.
Do not attempt to diagnose such prob-
lems yourself. Instead, take the motor-
cycle to a Yamaha dealer. You shouldperiodically remove and inspect the
spark plugs because heat and deposits
will cause any spark plug to slowly
break down and erode. If electrode ero-
sion becomes excessive, or if carbon
and other deposits are excessive, you
should replace the spark plug with the
specified plug.1. Cylinder head cover

6Installation
1. Measure the electrode gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.
2. Clean the gasket surface. Wipe off
any grime from the threads.
3. Install the spark plugs and tighten
to the specified torque.
NOTE:@ If a torque wrench is not available when
you are installing a spark plug, a good
estimate of the correct torque is 1/4 to
1/2 turn past finger tight. Have the
spark plug tightened to the specified
torque as soon as possible. @4. Install the spark plug caps and the
cylinder head covers.

Engine oilOil level inspection
1. Place the motorcycle on a level
place and hold it in an upright posi-
tion. Warm up the engine for sev-
eral minutes.NOTE:@ Be sure the motorcycle is positioned
straight up when checking the oil level.
A slight tilt toward the side can result in
false readings. @

the oil level through the level win-
dow located at the lower part of
the left side crankcase cover.
NOTE:@ Wait a few minutes until the oil level
settles before checking. @3. The oil level should be between
the maximum and minimum
marks. If the level is low, fill the en-
gine with sufficient oil to the speci-
fied level.Engine oil replacement
1. Warm up the engine for a few min-
utes.
2. Stop the engine. Place an oil pan
under the engine and remove the
oil filler cap.
3. Remove the drain bolt and drain
the oil.
4. Reinstall the drain bolt and tighten
it to the specified torque.5. Fill the engine with sufficient rec-
ommended oil. Install the oil filler
cap and tighten it.

CAUTION:@ l
Do not put in any chemical addi-
tives. Engine oil also lubricates
the clutch and additives could
cause clutch slippage.

Be sure no foreign material en-
ters the crankcase.

66. Start the engine and warm it up for
a few minutes. While warming up,
check for oil leakage. If oil leakage
is found, stop the engine immedi-
ately and check for the cause.
NOTE:@ After the engine is started, the oil level
indicator light should go off if oil is filled
to the specified level. @
EC000067
CAUTION:@ If the indicator light flickers or re-
mains on, immediately stop the en-
gine and consult with a Yamaha
dealer. @Engine oil filter replacement
It is recommended that the oil filter be
changed by an authorized Yamaha
dealer due to necessary disassembly
of components that is only covered in
the service manual.

WARNING
@ Do not let foreign material enter the
final gear case. Be sure oil does not
get on the tire or wheel. @Oil level inspection
1. Place the motorcycle on a level
place and hold it in an upright posi-
tion. The engine should be cool at
ambient temperature.2. Remove the oil filler bolt and
check the oil level. The oil level
should be at the brim of the filler
hole. Add the recommended oil if
necessary.
Oil replacement
1. Place an oil pan under the final
gear case.
2. Remove the oil filler bolt and drain
bolt to drain the oil.

EC000082
CAUTION:@ l
Make sure the air filter is prop-
erly seated in the air filter case.
l
The engine should never be run
without the air filter installed.
Excessive piston and/or cylin-
der wear may result.

Carburetor adjustmentThe carburetors are important parts of
the engine and require very sophisti-
cated adjustment. Most adjustments
should be left to a Yamaha dealer who
has the professional knowledge and
experience to do so. However, the idle
speed may be adjusted by the owner
as part of routine maintenance.
EC000095
CAUTION:@ The carburetors were set at the
Yamaha factory after many tests. If
they are changed, poor engine per-
formance and damage may result.
EAU01168
Idle speed adjustmentNOTE:@ A diagnostic tachometer must be used
for this procedure. @1. Attach the tachometer. Start the
engine and warm it up for a few
minutes at approximately 1,000 to
2,000 r/min. Occasionally rev the
engine to 4,000 to 5,000 r/min.
The engine is warm when it quick-
ly responds to the throttle.

speed by adjusting the throttle
stop screw. Turn the screw in di-
rection
a to increase engine
speed and in direction
b to de-
crease engine speed.
NOTE:@ If the specified idle speed cannot be
obtained by performing the above ad-
justment, consult a Yamaha dealer. @

Throttle cable free play
inspectionThere should be a free play of 4 ~
6 mm at the throttle grip. If the free play
is incorrect, ask a Yamaha dealer to
make this adjustment.
EAU00637
Valve clearance adjustmentThe correct valve clearance changes
with use, resulting in improper fuel/air
supply or engine noise. To prevent this,
the valve clearance must be adjusted
regularly. This adjustment however,
should be left to a professional
Yamaha service technician.

Brake fluid replacementThe brake fluid should be replaced only
by trained Yamaha service personnel.
Have the Yamaha dealer replace the
following components during periodic
maintenance or when they are dam-
aged or leaking:l
oil seals (every two years)
l
brake hoses (every four years)

Cable inspection and
lubrication
EW000112
WARNING
@ Damage to the outer housing of ca-
bles may lead to internal rusting and
interfere with the cable movement.
Replace damaged cables as soon as
possible to prevent unsafe condi-
tions. @Lubricate the cables and cable ends. If
a cable does not operate smoothly, ask
a Yamaha dealer to replace it.
EAU00773
Throttle cable and grip
lubricationThe throttle twist grip assembly should
be greased at the time that the cable is
lubricated, since the grip must be re-
moved to get at the end of the throttle
cable. After removing the screws, hold
the end of the cable up in the air and
put in several drops of lubricant. With
the throttle grip disassembled, coat the
metal surface of the grip assembly with
a suitable all-purpose grease.
Recommended lubricant:

Front fork inspectionVisual check
EW000115
WARNING
@ Securely support the motorcycle so
there is no danger of it falling over. @Check for scratches or damage on the
inner tube and excessive oil leakage
from the front fork.
Operation check
1. Place the motorcycle on a level
place.
2. Hold the motorcycle in an upright
position and apply the front brake.
3. Push down hard on the handle-
bars several times and check if the
fork rebounds smoothly.
EC000098
CAUTION:@ If any damage or unsmooth move-
ment is found with the front fork,
consult a Yamaha dealer. @
EAU00794
Steering inspectionPeriodically inspect the condition of the
steering. Worn out or loose steering
bearings may be dangerous. Place a
stand under the engine to raise the
front wheel off the ground. Hold the
lower end of the front forks and try to
move them forward and backward. If
any free play can be felt, ask a Yamaha
dealer to inspect and adjust the steer-
ing. Inspection is easier if the front
wheel is removed.
