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:

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.

1. Torque wrench
7. Install the new oil filter and tighten
it to the specified torque with an oil
filter wrench.
NOTE:
When installing the oil filter, tighten it to
the proper torque by using a torque
wrench.
Tightening torque:
Oil filter:
17 Nm (1.7 mákg)
8. Fill the engine with sufficient oil to
reach the specified level. Install
the oil filler cap and tighten it.
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.

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.

Front fork inspection
Visual checkEW000115
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 inspection
Periodically 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.

c. Install the spark plug caps onto the
spark plugs and place the spark
plugs on the cylinder head so that
the electrodes are grounded. (This
will limit sparking during the next
step.)
d. Turn the engine over several times
with the starter. (This will coat the
cylinder walls with oil.)
e. Remove the spark plug caps from
the spark plugs, install the spark
plugs and then the spark plug
caps.
EWA00003
When turning the engine over, be
sure to ground the spark plug elec-
trodes to prevent damage or injury
from sparking.
6. Lubricate all control cables and
the pivoting points of all levers and
pedals as well as of the side-
stand/centerstand.7. Check and, if necessary, correct
the tire air pressure, then raise the
motorcycle so that both of its
wheels are off the ground. Alterna-
tively, turn the wheels a little every
month in order to prevent the tires
from becoming degraded in one
spot.
8. Cover up the muffler outlets with
plastic bags to prevent moisture
from entering.
9. Remove the battery and fully
charge it. Store it in a cool, dry
place and recharge it once a
month. Do not store the battery in
an excessively cold or warm place
(less than 0ûC or more than 30ûC).
For more information, see ÒBattery
storageÓ in the chapter ÒPERIOD-
IC MAINTENANCE AND MINOR
REPAIRSÓ.
NOTE:
Make any necessary repairs before
storing the motorcycle.
