TIPAir filter
 This model’s air filter uses a disposable oil-coated paper element. This element cannot be cleaned with compressed
air, doing so will only damage it.
 The air filter element needs to be replaced more frequently when riding in unusually wet or dusty areas.
Hydraulic brake service  Regularly check the front and rear brake fluid levels. Replenish if necessary.
 Every two years replace the rear brake master cylinder, the internal components of the front brake master cylinder, the
brake calipers, and change the brake fluid.
 Replace the brake hoses every four years or sooner if cracked or damaged.30 *Throttle g

Checkin g the spark plu gsThe 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.

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 for the oil level to settle for an accurate reading.
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. Check the dipstick O-ring fordamage, and replace it if neces-
sary.
6. If the engine oil is at or below the minimum level mark, remove the
engine oil filler cap, and then add
sufficient oil of the recommended
type to raise it to the correct level. 7. Check the filler cap O-ring for
damage, and replace it if neces-
sary.
8. Insert and tighten the engine oil dipstick, and then install and tight-
en the oil filler cap.
To chan ge the en gine oil (with or
without oil filter cartri dge replace-
ment) 1. Place the vehicle on a level sur- face.
2. Remove cowlings A and B. (See page 7-9.)

TIPBe sure to wipe off spilled oil on any
parts after the engine and exhaust sys-
tem have cooled down.NOTICE
ECA11621
 In or der to prevent clutch slip-
pa ge (since the en gine oil also
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-
er quality than specifie d. In
a ddition, do not use oils lab eled
“ENERGY CONSERVING II” or
hi gher.
 Make sure that no forei gn mate-
rial enters the crankcase.
15. Check the filler cap O-ring for damage, and replace it if neces-
sary.
16. Install and tighten the oil filler cap.
17. 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.TIPAfter the engine is started, the engine
oil level warning light should go off if
the oil level is sufficient.NOTICE
ECA10402
If the oil level warnin g li ght flickers
or remains on even if the oil level is
correct, imme diately turn the en gine
off an d have a Yamaha dealer check
the vehicle.18. Turn the engine off, and then check the oil level and correct it if
necessary.
19. Check the dipstick O-ring for damage, and replace it if neces-
sary.
20. Install the cowlings.

Why Yamalu beYAMALUBE oil is a Genuine YAMAHA
Part born of the engineers’ passion
and belief that engine oil is an impor-
tant liquid engine component. We form
teams of specialists in the fields of me-
chanical engineering, chemistry, elec-
tronics and track testing, and have
them develop the engine together with
the oil it will use. Yamalube oils take full
advantage of the base oil’s qualities
and blend in the ideal balance of addi-
tives to make sure the final oil clears
our performance standards. Thus,
Yamalube mineral, semisynthetic and
synthetic oils have their own distinct
characters and value. Yamaha’s expe-
rience gained over many years of re-
search and development into oil since
the 1960’s helps make Yamalube the
best choice for your Yamaha engine.

Brake li ght switchesThe brake light should come on just
before braking takes effect. The brake
light is activated by switches connect-
ed to the brake lever and brake pedal.
Since the brake light switches are
components of the anti-lock brake sys-
tem, they should only be serviced by a
Yamaha dealer.

Supportin g the motorcycleSince this model is not equipped with a
centerstand, use maintenance stands
when removing the front or rear wheel
or when performing other maintenance
that requires the motorcycle to stand
up right.
Check that the motorcycle is in a stable
and level position before starting any
maintenance.
EAU25872
Trou bleshootin gAlthough Yamaha motorcycles receive
a thorough 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 charts
represent quick and easy procedures
for checking these vital systems your-
self. However, should your motorcycle
require any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the motorcycle
properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills.
