Tips for reducing fuel
consumption
Fuel 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).
EAU16841
Engine break-in
There 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.
EAU17100
0–1000 km (0–600 mi)
Avoid prolonged operation above 4000
r/min.
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 6000
r/min.
CAUTION:

ECA11150
After 1000 km (600 mi) of operation,the engine oil must be changed, and
the oil filter element replaced.
1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.
CAUTION:

ECA10310

Keep the engine speed out of
the tachometer red zone.

If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the vehi-
cle.

Parking
When parking, stop the engine, and
then remove the key from the main
switch.
WARNING

EWA10310

Since the engine and exhaust
system can become very hot,
park in a place where pedestri-
ans or children are not likely to
touch them.

Do not park on a slope or on soft
ground, otherwise the vehicle
may overturn.
CAUTION:

ECA10380
Never park in an area where there
are fire hazards such as grass or
other flammable materials.

PERIODIC MAINTENANCE AND MINOR REPAIR

Safety is an obligation of the owner. Pe-
riodic inspection, adjustment and lubri-
cation will keep your vehicle in the
safest and most efficient condition pos-
sible. The most important points of in-
spection, adjustment, and lubrication
are explained on the following pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a gen-
eral guide under normal riding condi-
tions. However, DEPENDING ON THE
WEATHER, TERRAIN, GEOGRAPHI-
CAL LOCATION, AND INDIVIDUAL
USE, THE MAINTENANCE INTER-
VALS MAY NEED TO BE SHORT-
ENED.
WARNING

EWA10320
If you are not familiar with mainte-
nance work, have a Yamaha dealer
do it for you.

Owner’s tool kit
The owner’s tool kit is located inside the
storage compartment under the seat.
(See page 3-14.)
The service information included in this
manual and the tools provided in the
owner’s tool kit are intended to assist
you in the performance of preventive
maintenance and minor repairs. How-
ever, additional tools such as a torque
wrench may be necessary to perform
certain maintenance work correctly.
NOTE:

If you do not have the tools or experi-
ence required for a particular job, have
a Yamaha dealer perform it for you.
WARNING

EWA10350
Modifications not approved by
Yamaha may cause loss of perfor-
mance and render the vehicle un-
safe for use. Consult a Yamaha
dealer before attempting any chang-
es.

NOTE:


The annual checks must be performed every year, except if a kilometer-based maintenance, or for the UK, a
mileage-based maintenance, is performed instead.

From 50000 km (30000 mi), repeat the maintenance intervals starting from 10000 km (6000 mi).

Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and technical
skills.

NOTE:


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.

quick fastener.NOTE:

To install the quick fastener, push the
center pin out so that it will protrude
from the fastener head, insert the fas-
tener into the cowling, and then push
the protruding pin in until it is flush with
the fastener head.

To remove one of the panels
1. Remove the corresponding cowl-
ing A or B. (See page 6-6.)
2. Remove the seat. (See
page 3-14.)
3. Remove the screw, and then take
the panel off.To install the panel
1. Place the panel in the original po-
sition, and then install the screw.
2. Install the seat and the cowling.

EAU19642
Checking the spark plugs
The spark plugs are important engine
components, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode,
they should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plugs can re-
veal the condition of the engine.
The porcelain insulator around the cen-
ter 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 en-
gine should have the same color. If any
spark plug shows a distinctly different
color, the engine could be operating im-
properly. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the vehicle.
If a spark plug shows signs of electrode
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.
NOTE:

If 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.
EAU19832
Engine oil and oil filter
element
The 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 level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
NOTE:

Make sure that the vehicle is positioned
straight up when checking the oil level.
A slight tilt to the side can result in a
false reading.
2. Start the engine, warm it up for 15
minutes, and then turn it off.
3. Wait a few minutes until the oil set-
tles, remove the oil filler cap, wipe
the dipstick clean, insert it back
into the oil filler hole (without
screwing it in and with the arrow
mark pointing upward as shown),
and then remove it again to check
