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, replacement,
or repair of the emission control devic-
es and systems may be performed by
any repair establishment or individual
that is certified (if applicable). Yamaha
dealers are trained and equipped to
perform these particular services.

Tool kit
The tool kit is located under the seat.
(See page 3-11.)
The information included in this manual
and the tools provided in the tool kit are
intended to assist you in the perfor-
mance of preventive maintenance and
minor repairs. However, a torque
wrench and other tools are necessary
to perform certain maintenance work
correctly.
TIP
If you do not have the tools or experi-
ence required for a particular job, have
your Yamaha dealer perform it for you.

Checking the spark plugs
The spark plugs are important engine
components, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode,
they should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plugs can re-
veal the condition of the engine.
The porcelain insulator around the cen-
ter electrode of each spark plug should
be a medium-to-light tan (the ideal color
when the vehicle is ridden normally),
and all spark plugs installed in the en-
gine should have the same color. If any
spark plug shows a distinctly different
color, the engine could be operating im-
properly. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the vehicle.
If a spark plug shows signs of electrode
erosion and excessive carbon or other
deposits, it should be replaced.
Before installing a spark plug, the spark
plug gap should be measured with a
wire thickness gauge and, if necessary,
adjusted to specification. Clean the surface of the spark plug
gasket and its mating surface, and then
wipe off any grime from the spark plug
threads.
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 speci-
fied torque as soon as possible.

NGK/CR7E

14 To change the engine oil (and re-
place the oil filter cartridge)
1. Place the vehicle on a level sur- face.
2. Start the engine, warm it up for several minutes, and then turn it
off.
3. Place an oil pan under the engine to collect the used oil.
4. Remove the engine oil filler cap, and then the engine oil drain bolt
and its gasket.
5. Check the O-ring for damage and replace it if necessary.
TIP
Skip steps 6–8 if the oil filter cartridge is
not being replaced. 6. Remove the oil filter cartridge with
an oil filter wrench.
TIP
An oil filter wrench is available at a
Yamaha dealer.
7. Apply a thin coat of clean engine oil to the O-ring of the new oil filter
cartridge.
TIP
Make sure that the O-ring is properly
seated.
8. Install the new oil filter cartridge, and then tighten it to the specified
torque with a torque wrench.

tem have cooled down.
NOTICE
ECA11621
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.
Make sure that no foreign mate-
rial enters the crankcase.
12. Start the engine, and then let it idle for several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
13. Turn the engine off, and then check the oil level and correct it if
necessary.
14. Reset the oil change indicator. (See page 5-10.)

Cast wheels
To maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points regarding the
specified wheels.
The wheel rims should be checked
for cracks, bends, warpage or oth-
er damage before each ride. If any
damage is found, have a Yamaha
dealer replace 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.
After repairing or replacing the
front tire, tighten the valve stem nut
and locknut to the specified
torques.

Checking the front and rear
brake lever free play
Front
Rear
There should be no free play at the
brake lever ends. If there is free play,
have a Yamaha dealer inspect the
brake system.
WARNING
EWA14212
A soft or spongy feeling in the brake
lever can indicate the presence of air
in the hydraulic system. If there is air
in the hydraulic system, have a
Yamaha dealer bleed the system be-
fore operating the vehicle. Air in the
hydraulic system will diminish the
braking performance, which may re-
sult in loss of control and an acci-
dent.

Troubleshooting
Although your Yamaha received a thor-
ough inspection before shipment from
the factory, trouble may occur during
operation. Any problem in the fuel,
compression, or ignition systems, for
example, can cause poor starting and
loss of power.
The following troubleshooting chart
represents a quick and easy procedure
for checking these vital systems your-
self. However, should your vehicle re-
quire any repair, take it to an authorized
Yamaha dealer whose skilled techni-
cians have the necessary tools, experi-
ence, and know-how to properly
service your Yamaha vehicle.
Be sure to use only genuine Yamaha
replacement parts. Although imitation
parts may look similar to genuine parts,
they are often inferior in quality, have a
shorter service life, and can lead to an
expensive repair bill later on.
WARNING
EWA15142
When checking the fuel system, do
not smoke, and make sure there are
no open flames or sparks in the ar-
ea, including pilot lights from water
heaters or furnaces. Gasoline or
gasoline vapors can ignite or ex-
plode, causing severe injury or
property damage.
EAU77992Smart key system troubleshooting
Please check the following items when
the smart key system does not work.
Is the smart key turned on? (See
page 3-5.)
Is the smart key battery dis-
charged? (See page 3-6.)
