
Even with the transmission in
the neutral position, do not
coast for long periods of time
with the engine off, and do not
tow the motorcycle for long dis-
tances. The transmission is
properly lubricated only when
the engine is running. Inade-
quate lubrication may damage
the transmission.

Always use the clutch while
changing gears to avoid damag-
ing the engine, transmission,
and drive train, which are not
designed to withstand theshock of forced shifting.
EAU16811
Tips for reducing fuel
consumptionFuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:
Shift up swiftly, and avoid high en-
gine speeds during acceleration.

Do not rev the engine while shifting
down, and avoid high engine
speeds with no load on the engine.

Turn the engine off instead of let-
ting it idle for an extended length of
time (e.g., in traffic jams, at traffic
lights or at railroad crossings).
EAU16842
Engine break-inThere is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided.
EAU17094
0–1000 km (0–600 mi)
Avoid prolonged operation above 3500
r/min. NOTICE: After 1000 km (600
mi) of operation, the engine oil must
be changed and the oil filter car-
tridge or element replaced.
[ECA10303]
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 4200

TIP
Air filter
This model’s air intake system is equipped with a disposable oil-coated paper element. The air filter element cannot
be cleaned with compressed air, it must be replaced.
The air filter element needs to be replaced more fr equently when riding in unusually wet or dusty areas.

Hydraulic brake service
After disassembling the brake master cylinder and caliper, always change the fluid. Regularly check the brake fluid
level and fill the reservoir as required.
Every two years replace the internal components of the brake master cylinder and caliper, and change the brake fluid. Replace the brake hose every four years and if cracked or damaged.

12 spark plug wrench, and then tight-
en it to the specified torque.
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 speci-fied torque as soon as possible.
3. Install the spark plug cap.
EAU59622
Engine oil and oil filter
elementThe engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter ele-
ment replaced at the intervals specified
in the periodic maintenance and lubri-
cation chart.
To check the engine oil level1. Start the engine, warm it up for several minutes, and then turn it
off.
2. On a level surface, place the vehi- cle on the centerstand.
3. Wait a few minutes until the oil set- tles. Remove the engine oil filler
cap, wipe the dipstick clean, insert
it back into the oil filler hole (with-
out screwing it in), and then re-
move it again to check the oil level.
WARNING! Never remove the
engine oil filler cap after
high-speed operation, other-
wise hot engine oil could spout
out and cause damage or injury.
Always let the engine oil cool
down sufficiently before remov- ing the oil filler cap.
[EWA17640]
TIPThe engine oil should be between theminimum and maximum level marks.
4. If the engine oil is below the mini- mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
5. Install the oil filler cap.

To change the engine oil (with or
without oil filter element 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. Loosen the oil filter element cover bleed bolt and oil filter element
drain bolt.
4. Remove the engine oil drain bolt and its gasket to drain the oil from
the crankcase. 5. Remove the engine oil filler cap,
the engine oil tank drain bolt and
its gasket to drain the oil from the
oil tank. 6. Remove the oil filter element drain
bolt to drain the oil from the oil filter
element.
TIPSkip steps 7–9 if the oil filter element isnot being replaced.
7. Remove the oil filter element cover by removing the bolts.
8. Remove and replace the oil filter element and O-rings.TIPMake sure that the O-rings are properlyseated.


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 vaporlock.
NOTICE
ECA17641
Brake fluid may damage painted sur-
faces or plastic parts. Always cleanup spilled fluid immediately.
As the brake pads wear, it is normal for
the brake fluid level to gradually go
down. A low brake fluid level may indi-
cate worn brake pads and/or brake sys-
tem 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 riding.
EAU22724
Changing the brake fluid Have a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and lubrica-
tion chart. In addition, have the oil seals
of the brake master cylinder and caliper
as well as the brake hose replaced at
the intervals listed below or whenever
they are damaged or leaking.
Oil seals: Replace every two
years.

Brake hose: Replace every four
years.
