Fuel tank overflow hose
Before operating the vehicle:
zCheck the fuel tank overflow hose
connection and routing.
zCheck the fuel tank overflow hose
for cracks or damage, and replace
it if necessary.
zMake sure that the fuel tank over-
flow hose is not blocked, and
clean it if necessary.
EAU13434
Catalytic converter
This model is equipped with a catalytic
converter in the exhaust system.
WARNING
EWA10863
The exhaust system is hot after op-
eration. To prevent a fire hazard or
burns:
zDo not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.
zPark the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.
zMake sure that the exhaust sys-
tem has cooled down before
doing any maintenance work.
zDo not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up of
heat.
NOTICE
ECA10702
Use only unleaded gasoline. The use
of leaded gasoline will cause unre-
pairable damage to the catalytic
converter.

Tips for reducing fuel con-
sumption
Fuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
zAvoid high engine speeds during
acceleration.
zAvoid high engine speeds with no
load on the engine.
zTurn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at traf-
fic lights or at railroad crossings).
EAU16842
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 fol-
lowing 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.
EAU74660
0–1000 km (0–600 mi)
Avoid prolonged operation above 1/3
throttle. NOTICE: After 1000 km (600
mi) of operation, be sure to replace
the engine oil and clean the oil
strainer, and replace the final trans-
mission oil.
[ECA23650]
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 1/2
throttle.
1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.
NOTICE
ECA10271
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

Parking
When parking, stop the engine, and
then remove the key from the main
switch.
WARNING
EWA10312
zSince the engine and exhaust
system can become very hot,
park in a place where pedestri-
ans or children are not likely to
touch them and be burned.
zDo not park on a slope or on soft
ground, otherwise the vehicle
may overturn, increasing the
risk of a fuel leak and fire.
zDo not park near grass or other
flammable materials which
might catch fire.

TIP
zThe annual checks must be performed every year, except if a kilometer-
based maintenance, or for the UK, a mileage-based maintenance, is
performed instead.
zFrom 20000 km (12000 mi), repeat the maintenance intervals starting from
4000 km (2400 mi).
zItems marked with an asterisk should be performed by a Yamaha dealer as
they require special tools, data and technical skills.

Valve clearance
The valve clearance changes with use,
resulting in improper air-fuel mixture
and/or engine noise. To prevent this
from occurring, the valve clearance
must be adjusted by a Yamaha dealer
at the intervals specified in the periodic
maintenance and lubrication chart.
EAU69760
Tires
Tires are the only contact between the
vehicle and the road. Safety in all con-
ditions of riding depends on a relatively
small area of road contact. Therefore, it
is essential to maintain the tires in good
condition at all times and replace them
at the appropriate time with the speci-
fied tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
WARNING
EWA10504
Operation of this vehicle with im-
proper tire pressure may cause se-
vere injury or death from loss of
control.
zThe tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperature
of the tires equals the ambient
temperature).
zThe tire air pressure must be
adjusted in accordance with the
riding speed and with the total
weight of rider, passenger, car-
go, and accessories approved
for this model.

Troubleshooting
Although Yamaha vehicles 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 vehicle re-
quire any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the vehicle prop-
erly.
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.
WARNING
EWA15142
When checking the fuel system, do
not smoke, and make sure there are
no open flames or sparks in the ar-
ea, including pilot lights from water
heaters or furnaces. Gasoline or
gasoline vapors can ignite or ex-
plode, causing severe injury or prop-
erty damage.
