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.
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
specified torque as soon as possible.

En
gine oil an d oil filter car-
tri dgeThe engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the en gine oil level
1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion. 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.
4. 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
minimum and maximum level marks.
5. If the engine oil is at or below theminimum level mark, add suffi-
cient oil of the recommended type
to raise it to the correct level.
6. Insert the dipstick into the oil filler hole, and then tighten the oil filler
cap.
To chan ge the en gine oil (with or
without oil filter cartri dge replace-
ment) 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.
TIPSkip steps 4–6 if the oil filter cartridge
is not being replaced.4. Remove the oil filter cartridge withan oil filter wrench.

cartridge.TIPMake sure that the O-ring is properly
seated.6. Install the new oil filter cartridgewith an oil filter wrench, and then
tighten it to the specified torque
with a torque wrench. 7. Install the engine oil drain bolt and
its new gasket, and then tighten
the bolt to the specified torque.
8. Refill with the specified amount of the recommended engine oil, and
then install and tighten the oil filler
cap.

lu bricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a hi gh-

a dd ition, do not use oils la bele d
“ENERGY CONSERVING II” or

for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.
TIPAfter the engine is started, the engine
oil level warning light should go off if
the oil level is sufficient.NOTICE

Replacin g the air filter ele-
mentThe air filter element should be re-
placed at the intervals specified in the
periodic maintenance and lubrication
chart. Replace the air filter element
more frequently if you are riding in un-
usually wet or dusty areas.
To replace the air filter element
1. Remove the air filter case cover by removing the bolts.
2. Pull the air filter element out. 3. Insert a new air filter element into
the air filter case. NOTICE: Make
sure that the air filter element is
properly seate d in the air filter
case. The en gine shoul d never
b e operated without the air filter
element installe d, otherwise the
piston(s) an d/or cylin der(s) may
b ecome excessively worn.

Checking the throttle grip free
playThe throttle grip free play should mea-
sure 4.0–6.0 mm (0.16–0.24 in) at the
inner edge of the throttle grip. Periodi-
cally check the throttle grip free play
and, if necessary, have a Yamaha deal-
er adjust it.
EAU21402
Valve clearanceThe valve clearance changes with use,
resulting in improper air-fuel mixture
and/or engine noise. To prevent this
from occurring, the valve clearance
must be adjusted by a Yamaha dealer
at the intervals specified in the periodic
maintenance and lubrication chart.

TiresTires are the only contact between the
vehicle and the road. Safety in all con-
ditions of riding depends on a relatively
small area of road contact. Therefore, it
is essential to maintain the tires in good
condition at all times and replace them
at the appropriate time with the speci-
fied tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
WARNING

Operation of this vehicle with im-
proper tire pressure may cause se-
vere injury or d eath from loss of

Tire inspection
The tires must be checked before each
ride. If the center tread depth reaches
the specified limit, if the tire has a nail
or glass fragments in it, or if the side-
wall is cracked, have a Yamaha dealer
replace the tire immediately.TIPThe tire tread depth limit may differ
from country to country. Always com-
ply with the local regulations.

Cast wheelsTo 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, warp-
age or other 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 de-
formed 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.

Front brake pad s
Each front brake pad is provided with
wear indicator grooves, which allow
you to check the brake pad wear with-
out having to disassemble the brake.
To check the brake pad wear, check
the wear indicator grooves. If a brake
pad has worn to the point that the wear indicator grooves have almost disap-
peared, have a Yamaha dealer replace
the brake pads as a set.
