NOTICE
ECA11401
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,
as well as to the exhaust system.
TIPThis mark identifies the recom-
mended fuel for this vehicle as
specified by European regulation
(EN228).
Check that gasoline nozzle has
the same identifier when fueling.Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
95 or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand or premium unleaded fuel. Use
of unleaded fuel will extend spark plug
life and reduce maintenance costs.Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that con-
taining methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10% (E10). Gas-
ohol containing methanol is not
recommended by Yamaha because it
can cause damage to the fuel system
or vehicle performance problems.
Recommended fuel:
Premium unleaded gasoline (E10
acceptable)
Fuel tank capacity:
16 L (4.2 US gal, 3.5 Imp.gal)

Engine oil and oil filter car-
tridgeThe 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 chart.
To check the engine 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,
and then check the oil level
through the engine oil level check
window.4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to raise
it to the maximum level mark.
TIPCheck the O-ring for damage, and re-
place it if necessary.
To change the engine oil (and re-
place the filter)
1. Place the vehicle on a level sur-
face.
2. Remove cowling A. (See page
6-9.)
3. Start the engine, warm it up for
several minutes, and then turn it
off.
4. Place an oil pan under the engine
to collect the used oil.
5. Remove the engine oil filler cap,
the engine oil drain bolt and its
gasket to drain the oil from the
crankcase.

Motorcycle care and storage

7chemicals 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 forplastic 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.
2. For drive chain-equipped models:
Dry and then lubricate the drive
chain to prevent rust.
3. Use a chrome polish to shine
chrome, aluminum, and stainless
steel parts. Often the thermally in-
duced discoloring of stainless
steel exhaust systems can be re-
moved through polishing.
4. Apply a corrosion protection spray
on all metal parts including
chrome or nickel-plated surfaces.
WARNING! Do not apply sili-
cone or oil spray to seats, hand
grips, rubber foot pegs or tire
treads. Otherwise these parts
