To install the panel
1. Place the panel in the original posi-
tion, and then install the bolt.
2. Install the seat.
EAU19604
Checking the spark plug The spark plug is an important engine
component, which is easy to check.
Since heat and deposits will cause any
spark plug to slowly erode, the spark
plug should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plug can re-
veal the condition of the engine.
To remove the spark plug 1. Remove the spark plug cap.
2. Remove the spark plug as shown, with the spark plug wrench includ-
ed in the owner’s tool kit. To check the spark plug
1. Check that the porcelain insulator around the center electrode of the
spark plug is a medium-to-light tan
(the ideal color when the vehicle is
ridden normally).
TIPIf the spark plug shows a distinctly dif-
ferent color, the engine could be oper-
ating improperly. Do not attempt to
diagnose such problems yourself. In-
stead, have a Yamaha dealer check
the vehicle.

72. Check the spark plug for electrode
erosion and excessive carbon or
other deposits, and replace it if
necessary.
3. Measure the spark plug gap with a wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion. To install the spark plug
1. Clean the surface of the spark plug gasket and its mating surface, 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.
TIPIf 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.3. Install the spark plug cap.
EAU39845
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 engine oil level1. Place the motorcycle on a level surface and hold it in an upright po-
sition. A slight tilt to the side can re-
sult 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.TIPThe engine oil should be between the
tip of the dipstick and the maximum lev-
el mark.

4. If the engine oil is not between the
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 change the engine 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 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.
6. Start the engine, and then let it idlefor several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately 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.

Cleaning the air filter element The air filter element should be cleaned
or replaced at the intervals specified in
the periodic maintenance and lubrica-
tion chart. Clean or, if necessary, re-
place the air filter element more
frequently if you are riding in unusually
wet or dusty areas.
To clean the air filter element1. Remove panel A. (See page 7-7.)
2. Remove the air filter case cover by removing the screws.
3. Pull the sponge material and the air filter mesh out. 4. Clean the mesh with solvent, and
then wipe the solvent off.
5. Clean the sponge material with solvent, and then squeeze the re-
maining solvent out. WARNING!
Use only a dedicated parts
cleaning solvent. To avoid the
risk of fire or explosion, do not
use gasoline or solvents with a
low flash point.
[EWA10431]
NOTICE:
To avoid damaging the foam
material, handle it gently and
carefully, and do not twist or
wring it.
[ECA10511]
6. Apply oil of the recommended type to the entire surface of the sponge
material, and then squeeze the ex-
cess oil out.TIPThe sponge material should be wet but
not dripping.7. Insert the mesh and the spongematerial into the air filter case.
NOTICE: Make sure that the
mesh and the sponge material
are properly seated in the air fil-
ter case. The engine should
never be operated without the

●
Always let the exhaust system
cool prior to touching exhaust
components.
●
Do not start the engine when
cleaning the exhaust system.
TIPMake sure to select a well-ventilated
area free of combustible materials to
clean the spark arrester.1. Remove the tailpipe by removingthe 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 ar-
rester portion of the tailpipe and in-
side of the tailpipe housing. 3. Insert the tailpipe into the muffler,
and then install and tighten the
bolts to the specified torque.
TIPMake sure to align the bolt holes when
inserting the tailpipe.

Adjusting the carburetor The carburetor is an important part of
the engine and requires very sophisti-
cated adjustment. Therefore, most car-
buretor adjustments should be left to a
Yamaha dealer, who has the neces- sary professional knowledge and expe-
rience. The adjustment described in the
following section, however, may be ser-
viced by the owner as part of routine
maintenance.NOTICE
ECA10550
The carburetor has been set and ex-
tensively tested at the Yamaha fac-
tory. Changing these settings
without sufficient technical knowl-
edge may result in poor perfor-
mance of or damage to the engine.

Adjusting the engine idling
speed The engine idling speed must be
checked and, if necessary, adjusted as
follows at the intervals specified in the
periodic maintenance and lubrication
chart.TIPA diagnostic tachometer is needed to
make this adjustment.1. Attach the tachometer to the spark plug lead.
2. Start the engine and warm it up for several minutes at 1000–2000
r/min while occasionally revving it
to 4000–5000 r/min.TIPThe engine is warm when it quickly re-
sponds to the throttle.3. Check the engine idling speedand, if necessary, adjust it to spec-
ification by turning the throttle stop
screw. To increase the engine
idling speed, turn the screw in di- rection (a). To decrease the en-
gine idling speed, turn the screw in
direction (b).
TIPIf the specified idling speed cannot be
obtained as described above, have a
Yamaha dealer make the adjustment.1. Throttle stop screw
