TIP Air filter
• This model’s air filter is equipped with a disposable oil-coated paper element, which must not be cleaned with com- pressed air to avoid damaging it.
• The air filter element needs to be replaced more frequently when riding in unusually wet or dusty areas.
 Hydraulic brake service
• Regularly check and, if necessary, correct the brake fluid level.
• Every two years replace the internal components of the brake master cylinders and calipers, and change the brake fluid.
• Replace the brake hoses every four years and if cracked or damaged.

Checkin
g the spark plug sThe spark plugs are important engine
components, which should be
checked periodically, preferably by a
Yamaha dealer. Since heat and depos-
its will cause any spark plug to slowly
erode, they should be removed and
checked in accordance with the peri-
odic maintenance and lubrication
chart. In addition, the condition of the
spark plugs can reveal the condition of
the engine.
The porcelain insulator around the
center 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 engine should have the same
color. If any spark plug shows a dis-
tinctly different color, the engine could
be operating improperly. Do not at-
tempt to diagnose such problems
yourself. Instead, have a Yamaha deal-
er check the vehicle.
If a spark plug shows signs of elec-
trode 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.

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.NOTICE

Do not use any tools to remove or in-
stall the spark plu g cap, otherwise
the i gnition coil coupler may get
d amag ed . The spark plu g cap may
b e difficult to remove b ecause the
ru bber seal on the en d of the cap fits
ti g htly. To remove the spark plu g
cap, simply twist it b ack and forth
while pullin g it out; to install it, twist
it back an d forth while pushin g it in.

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 surfa- ce 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 dipstick and wipe it clean, insert it back
into the 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, remove the
engine oil filler cap, and then add
sufficient oil of the recommended
type to raise it to the correct level.1. Engine oil dipstick
