a. Spark plug gap
EAU01880
Spark plug inspection
The 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 speci-
fication.Specified spark plug:
CR8E (NGK) or
U24ESR-N(DENSO)
Spark plug gap:
0.7 ~ 0.8 mm

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.Tightening torque:
Spark plug:
12.5 Nm (1.25 mákg)

Engine oil
Oil level inspection
1. Place the motorcycle on the cen-
terstand. Warm up the engine for
several 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.
1. Engine oil filler cap
2. With the engine stopped, check
the oil level through the level win-
dow 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 oil to reach the
specified level.

EC000066
CAUTION:
lDo not put in any chemical addi-
tives. Engine oil also lubricates
the clutch and additives could
cause clutch slippage.
lBe sure no foreign material en-
ters the crankcase. Recommended oil:
See page 8-1.
Oil quantity:
Total amount:
3.1 L
Periodic oil change:
2.3 L
With oil filter replacement:
2.6 L
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.

5. Remove the air filter case cover by
removing the screws.
6. Pull out the air filter.7. Tap the air filter lightly to remove
most of the dust and dirt. Blow out
the remaining dirt with com-
pressed air as shown. If the air fil-
ter is damaged, replace it.
8. Reassemble by reversing the re-
moval procedure.
EC000082
CAUTION:
lMake sure the air filter is prop-
erly seated in the air filter case.
lThe engine should never be run
without the air filter installed.
Excessive piston and/or cylin-
der wear may result.

Carburetor adjustment
The 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.

Idle speed adjustment
1. 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 quickly responds to the
throttle.
2. Set the idle to the specified engine
speed by adjusting the throttle
stop screw. Turn the screw in di-
rectiona
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.Standard idle speed:
1,200 ~ 1,300 r/min

Valve clearance adjustment
The 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.
EAU00647
Tires
To ensure maximum performance,
long service, and safe operation, note
the following:
Tire air pressure
Always check and adjust the tire pres-
sure before operating the motorcycle.
EW000082
Tire inflation pressure should be
checked and adjusted when the
temperature of the tire equals the
ambient air temperature. Tire infla-
tion pressure must be adjusted ac-
cording to total weight of cargo,
rider, passenger, and accessories
(fairing, saddlebags, etc. if approved
for this model), and vehicle speed.

justing nut exactly the same
amount to maintain correct axle
alignment. There are marks oneach side of the swingarm. Use
these marks to align the rear
wheel.
EC000096
CAUTION:
Too little chain slack will overload
the engine and other vital parts.
Keep the slack within the specified
limits.
3. After adjusting, tighten the lock-
nuts. Then tighten the axle nut to
the specified torque.

EAU00769
Drive chain lubrication
The chain consists of many parts which
work with each other. If the chain is not
maintained properly, it will wear out
quickly. Therefore, the chain must be
serviced regularly. This service is es-
pecially necessary when riding in dusty
areas. This motorcycle is equipped
with a sealed type chain. Steam clean-
ing, high-pressure washes, and sol-
vents can damage chain so do not use
these for cleaning it. Use only kerosene
to clean the drive chain. Wipe it dry,
and thoroughly lubricate it with SAE 30
~ 50W motor oil. Do not use any other
lubricants on the drive chain. They may
contain solvents that could damage the
sealed chain.
EC000097
CAUTION:
Be sure to oil the chain after wash-
ing the motorcycle or riding in the
rain.

Cable inspection and
lubrication
EW000112
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.
Recommended lubricant:
Engine oil
EAU00773
Throttle cable and grip
lubrication
The 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.
