Emission controls not only function to
ensure cleaner air, but are also vital to
proper engine operation and maximum
performance. In the following periodic
maintenance charts, the services relat-
ed to emissions control are grouped
separately. These services require
specialized data, knowledge, and
equipment. Maintenance, replace-
ment, or repair of the emission control
devices and systems may be per-
formed by any repair establishment or
individual that is certified (if applicable).
Yamaha dealers are trained and equipped to perform these particular
services.

Owner’s tool kit
The service information included in this
manual and the tools provided in the
owner’s tool kit are intended to assist
you in the performance of preventive
maintenance and minor repairs. How-
ever, additional tools such as a torque
wrench may be necessary to perform
certain maintenance work correctly.
TIP
If you do not have the tools or experi-
ence required for a particular job, have
a Yamaha dealer perform it for you.

To install the spark plu
g
1. Clean the surface of the spark plug gasket and its mating surfa-
ce, and then wipe off any grime
from the spark plug threads.
2. Install the spark plug with the spark plug wrench, and then tight-
en it to the specified torque.
TIP
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is 1/4–
1/2 turn past finger tight. However, the
spark plug should be tightened to the
specified torque as soon as possible.
3. Install the spark plug cap.
EAU39847
Engine oil
The engine oil level should be checked
before each ride. In addition, the oil
must be changed at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
To check the en gine oil level
1. Place the motorcycle on a level surface and hold it in an upright
position. 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.
3. Wait a few minutes until the oil set- tles, remove the engine oil filler
cap, wipe the engine oil dipstick
clean, insert it back into the oil filler
hole (without screwing it in), and
then remove it again to check the
oil level.
TIP
The engine oil should be between the
tip of the dipstick and the maximum
level mark.

tip of the dipstick and the maxi-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
5. Insert the dipstick into the oil filler hole, and then tighten the oil filler
cap.
To chan ge the en gine oil
1. Start the engine, warm it up for several minutes, and then turn it
off.
2. Place an oil pan under the engine to collect the used oil.
3. Remove the engine oil filler cap, the engine oil drain bolt and its
gasket to drain the oil from the
crankcase.
4. Install a new gasket and the drain bolt, and then tighten the drain
bolt to the specified torque.
5. Refill with the specified amount of the recommended engine oil, and
then install and tighten the oil filler
cap.
NOTICE

In or der to prevent clutch slip-
pa ge (since the en gine oil also
lu bricates the clutch), do not
mix any chemical add itives. Do
not use oils with a d iesel speci-
fication of “CD” or oils of a hi gh-
er quality than specified . In
a ddition, do not use oils la bele d
“ENERGY CONSERVING II” or
hi gher.
 Make sure that no forei gn mate-
rial enters the crankcase.
6. Start the engine, and then let it idle for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.
7. Turn the engine off, and then check the oil level and correct it if
necessary.

Cleanin g the spark arrester
The spark arrester should be cleaned
at the intervals specified in the periodic
maintenance and lubrication chart.
WARNING
EWA10981
 Always let the exhaust system
cool prior to touchin g exhaust
components.
 Do not start the en gine when
cleanin g the exhaust system.
TIP
Make sure to select a well-ventilated
area free of combustible materials to
clean the spark arrester.
1. Remove the tailpipe by removing
the bolts, and then pulling it out of
the muffler.
2. Tap the tailpipe lightly, and then use a wire brush to remove any
carbon deposits from the spark
arrester portion of the tailpipe and
inside of the tailpipe housing. 3. Insert the tailpipe into the muffler,
and then install and tighten the
bolts to the specified torque.
TIP
Make sure to align the bolt holes when
inserting the tailpipe.

Spoke wheels
WARNING
EWA10611
The wheels on this mo del are not
d esi gne d for use with tu beless tires.
Do not attempt to use tu beless tires
on this mo del.
To maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points
regarding the specified wheels.
 The wheel rims should be
checked for cracks, bends, warp-
age or other damage, and the
spokes for looseness or damage
before each ride. If any damage is
found, have a Yamaha dealer re-
place the wheel. Do not attempt
even the smallest repair to the
wheel. A deformed or cracked
wheel must be replaced.
 The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse han-
dling characteristics, and a short-
ened tire life.

Adjustin g the clutch free play
The clutch free play must be checked
and, if necessary, adjusted as follows
at the intervals specified in the periodic
maintenance and lubrication chart.
1. Loosen the locknut.
2. Slowly turn the clutch adjusting screw in direction (a) until resis-
tance is felt, and then turn it 1/8
turn in direction (b).
3. Tighten the locknut to the speci- fied torque.
TIP
When tightening the locknut, hold the
clutch adjusting screw with a screw-
driver so that it does not turn together
with the locknut.

2. To tighten the drive chain, turn thedrive chain slack adjusting nut at
each end of the swingarm in direc-
tion (a). To loosen the drive chain,
turn the adjusting nut at each end
of the swingarm in direction (b),
and then push the rear wheel for-
ward. NOTICE: Improper drive
chain slack will overload the en-
g ine as well as other vital parts
of the motorcycle an d can lead
to chain slippa ge or breakag e.
To prevent this from occurrin g,
keep the d rive chain slack with-
in the specifie d limits.
[ECA10572]
TIP
Using the alignment marks on each
side of the swingarm, make sure that
both drive chain pullers are in the same
position for proper wheel alignment.
3. Tighten the axle nut and both
locknuts to the specified torques.
4. Adjust the brake pedal free play. (See page 7-19.)
