mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
To change the engine oil (with or
without oil filter cartridge replace-
ment)
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 cowling by removing
the bolts.
5. Remove the engine oil filler cap,
the engine oil drain bolt and its
gasket to drain the oil from the
crankcase.
TIP
Skip steps 6…8 if the oil filter cartridge
is not being replaced.

6A low brake fluid level may indi-
cate worn brake pads or brake
system leakage; therefore, be sure
to check the brake pads for wear
and the brake system for leakage.
If the brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause before further rid-
ing.
WARNING
EWA15991
Improper maintenance can result in
loss of braking ability. Observe
these precautions:
Insufficient brake fluid may al-
low air to enter the brake sys-
tem, reducing braking
performance.
Clean the filler cap before re-
moving. Use only DOT 4 brake
fluid from a sealed container.
Use only the specified brake flu-
id; otherwise, the rubber seals
may deteriorate, causing leak-
age.
Refill with the same type of
brake fluid. Adding a brake fluid
other than DOT 4 may result in a
harmful chemical reaction.
Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vapor
lock.
EAU22734
Changing the brake fluid
Have a Yamaha dealer change the
brake fluid every 2 years. In addition,
have the seals of the master cylinders
and brake calipers, as well as the brake
hoses replaced at the intervals listed
below or sooner if they are damaged or
leaking.
Brake seals: every 2 years
Brake hoses: every 4 years

7 harsh chemicals, including
strong acidic wheel cleaners,
especially on spoke or magne-
sium wheels.
harsh chemicals, abrasive
cleaning compounds, or wax on
matte-finished parts. Brushes
can scratch and damage the
matte-finish, use soft sponge or
towel only.
towels, sponges, or brushes
contaminated with abrasive
cleaning products or strong
chemicals such as, solvents,
gasoline, rust removers, brake
fluid, or antifreeze, etc.
Before washing
1. Park the vehicle out of direct sun-
light and allow it to cool. This will
help avoid water spots.
2. Make sure all caps, covers, elec-
trical couplers and connectors are
tightly installed.
3. Cover the muffler end with a plas-
tic bag and a strong rubber band.
4. Pre-soak stubborn stains like in-
sects or bird droppings with a wet
towel for a few minutes.
5. Remove road grime and oil stains
with a quality degreasing agent
and a plastic-bristle brush or
sponge. NOTICE: Do not use
degreasing agent on areas re-
quiring lubrication such as
seals, gaskets, and wheel axles.
Follow product instructions.
[ECA26290]
Washing
1. Rinse off any degreaser and spray
down the vehicle with a garden
hose. Use only enough pressure
to do the job. Avoid spraying wa-
ter directly into the muffler, instru-
ment panel, air inlet, or other inner
areas such as underseat storage
compartments.
2. Wash the vehicle with a quality au-
tomotive-type detergent mixed
with cool water and a soft, clean
towel or sponge. Use an old tooth-
brush or plastic-bristle brush for
hard-to-reach places. NOTICE:
Use cold water if the vehicle has
been exposed to salt. Warm wa-
ter will increase salt’s corrosive
properties.
[ECA26301]
3. For windshield-equipped vehicles:
Clean the windshield with a soft
towel or sponge dampened with
water and a pH neutral detergent.
If necessary, use a high-quality
windshield cleaner or polish for
motorcycles. NOTICE: Never use
any strong chemicals to clean
the windshield. Additionally,
some cleaning compounds for
plastic may scratch the wind-
shield, so be sure to test all
cleaning products before gen-
eral application.
[ECA26310]
4. Rinse off thoroughly with clean
water. Be sure to remove all deter-
gent residues, as they can be
harmful to plastic parts.
After washing
1. Dry the vehicle with a chamois or
absorbent towel, preferably mi-
crofiber terrycloth.
