Spark plug inspectionThe spark plug is an important engine
component and should be inspected
periodically, preferably by a Yamaha
dealer. The condition of the spark plug
can indicate the condition of the en-
gine.
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. The spark
plugs should be periodically removed
and inspected because heat and de-
posits will cause any spark plug to
slowly break down and erode. If elec-
trode erosion becomes excessive, or if
carbon and other deposits are exces-
sive, the spark plug should be replaced
with the specified plug.
Before installing any spark plug, mea-
sure the electrode gap with a wire
thickness gauge and adjust it to specifi-
cation.When installing a spark plug, the gas-
ket surface should always be cleaned
and a new gasket used. Any grime
should be wiped off from the threads
and the spark plug tightened to the
specified torque.
NOTE:@ If a torque wrench is not available when
installing a spark plug, a good estimate
of the correct torque is 1/4 to 1/2 turn
past finger tight. The spark plug should
be tightened to the specified torque as
soon as possible. @

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 seve-
ral 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. @2. Stop the engine and wait for a few
minutes. Check the oil level
through the level window located
at the lower part of the right 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 recommended
oil to reach the specified level.Engine oil and oil filter cartridge re-
placement
1. Warm up the engine for several
minutes.

nearby Yamaha dealer. @5. Reinstall the drain bolt and tighten
it to the specified torque.
6. Apply a light coat of engine oil to
the O-ring of new oil filter.NOTE:@ Make sure the O-ring is seated properly. @

ommended oil. Install the oil filler
cap and tighten it.
EC000066
CAUTION:@ l
Do not put in any chemical addi-
tives. Engine oil also lubricates
the clutch and additives could
cause clutch slippage.
l
Be sure no foreign material en-
ters the crankcase.
@
9. Start the engine and warm it up for
several minutes. While warming
up, check for oil leakage. If oil
leakage is found, stop the engine
immediately and check for the
cause.NOTE:@ After the engine is started, the oil level
indicator light should go off if the oil is at
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. @

Coolant1. Remove panel C. (See page 7-8
for removal and installation proce-
dures.)
2. Check the coolant level in the res-
ervoir tank when the engine is cold
as the coolant level will vary with
engine temperature. The coolant
level should be between the maxi-
mum and minimum marks.3. If the level is low, remove the rider
seat, open the reservoir tank cap,
and add coolant or distilled water
to the specified level. (See page
3-15 for rider seat removal and in-
stallation procedures.)
4. Install the reservoir tank cap and
rider seat.
5. Install the panel.
EC000080
CAUTION:@ Hard water or salt water is harmful
to the engine. You may use distilled
water if you can’t get soft water. @NOTE:@ l
If water is added, have a Yamaha
dealer check the antifreeze con-
tent of the coolant as soon as pos-
sible.
l
Have a Yamaha dealer change
the coolant every two years.

The radiator fan operation is com-
pletely automatic. It is switched on
or off according to the coolant tem-
perature in the radiator.

removing the screws.5. Tap the air filter lightly to remove
most of the dust and dirt and blow
out the remaining dirt with com-
pressed air as shown. If the air fil-
ter is damaged, replace it.
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.

6. Fit the projection on the air filter el-
ement into the holder in the air fil-
ter case, and then tighten the
screws.
7. Install the air filter case cover and
tighten the bolts.
8. Insert the air filter case into the
carburetor intake joint and tighten
the clamp screw.

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.2. Set the idle to the specified engine
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. @1. Throttle stop screw
Standard idle speed:
950 ~ 1,050 r/min

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.

After repairing or replacing the

torque.
EAU00695
Clutch lever free play
adjustmentThis motorcycle has a hydraulic clutch.
There are no adjustments to perform
but the clutch system must be inspect-
ed periodically for proper fluid level and
leakage. If the control lever free play
becomes excessive and the motor-
cycle creeps or stalls when shifted into
gear, or if the clutch slips, causing ac-
celeration to lag behind engine speed,
there is probably air in the clutch sys-
tem and it must be bled out. Ask a
Yamaha dealer to do this service. Tightening torque:
