Be a Responsible Owner
As the vehicle’s owner, you are res-
ponsible for the safe and proper ope-
ration of your motorcycle.
Motorcycles are single-track vehicles.
Their safe use and operation are
dependent upon the use of proper
riding techniques as well as the
expertise of the operator. Every ope-
rator should know the following requi-
rements before riding this motorcycle.
He or she should:
●Obtain thorough instructions
from a competent source on all
aspects of motorcycle operation.
●Observe the warnings and main-
tenance requirements in this
Owner’s Manual.
●Obtain qualified training in safe
and proper riding techniques.
●Obtain professional technical
service as indicated in this
Owner’s Manual and/or when
made necessary by mechanical
conditions.Safe Riding
Perform the pre-operation checks
each time you use the vehicle to
make sure it is in safe operating con-
dition. Failure to inspect or maintain
the vehicle properly increases the
possibility of an accident or equip-
ment damage. See page 4-2 for a list
of pre-operation checks.
●This motorcycle is designed to
carry the operator and a passen-
ger.
●The failure of motorists to detect
and recognize motorcycles in
traffic is the predominating cause
of automobile/motorcycle acci-
dents. Many accidents have
been caused by an automobile
driver who did not see the
motorcycle. Making yourself
conspicuous appears to be very
effective in reducing the chance
of this type of accident.
Therefore:
• Wear a brightly colored jacket.
• Use extra caution when you
are approaching and passing
through intersections, sinceintersections are the most
likely places for motorcycle
accidents to occur.
• Ride where other motorists can
see you. Avoid riding in anot-
her motorist’s blind spot.
●Many accidents involve inexpe-
rienced operators. In fact, many
operators who have been invol-
ved in accidents do not even
have a current motorcycle licen-
se.
• Make sure that you are quali-
fied and that you only lend your
motorcycle to other qualified
operators.
• Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
• We recommend that you prac-
tice riding your motorcycle
where there is no traffic until
you have become thoroughly
familiar with the motorcycle
and all of its controls.
●Many accidents have been cau-
sed by error of the motorcycle
operator. A typical error made by
the operator is veering wide on a

EAU17241
Periodic inspection, adjustment, and
lubrication will keep your vehicle in
the safest and most efficient condi-
tion possible. Safety is an obligation
of the vehicle owner/operator. The
most important points of vehicle ins-
pection, 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
general guide under normal riding
conditions. However, depending on
the weather, terrain, geographical
location, and individual use, the main-
tenance intervals may need to be
shortened.
EWA10321
Failure to properly maintain the
vehicle or performing maintenance
activities incorrectly may increase
your risk of injury or death during
service or while using the vehicle. If
you are not familiar with vehicle
service, have a Yamaha dealer per-
form service.
EWA15121
Turn off the engine when perfor-
ming maintenance unless otherwi-
se specified.
●A running engine has moving
parts that can catch on body
parts or clothing and electrical
parts that can cause shocks or
fires.
●Running the engine while servi-
cing can lead to eye injury,
burns, fire, or carbon monoxide
poisoning – possibly leading to
death. See page 1-1 for more
information about carbon
monoxide.

Adjusting the carburetor
The carburetor is an important part of
the engine and requires very sophisti-
cated adjustment. Therefore, most
carburetor adjustments should be left
to a Yamaha dealer, who has the
necessary professional knowledge
and experience. The adjustment des-
cribed in the following section, howe-
ver, may be serviced by the owner as
part of routine maintenance.
ECA10550
The carburetor has been set and
extensively tested at the Yamaha
factory. Changing these settings
without sufficient technical know-
ledge may result in poor perfor-
mance of or damage to the engine.

Adjusting the engine idling
speed
The engine idling speed must be
checked and, if necessary, adjusted
as follows at the intervals specified in
the periodic maintenance and lubrica-
tion chart.

Cleaning and lubricating the
drive chain
The drive chain must be cleaned and
lubricated at the intervals specified in
the periodic maintenance and lubrica-
tion chart, otherwise it will quickly
wear out, especially when riding in
dusty or wet areas. Service the drive
chain as follows.
ECA10581
The drive chain must be lubricated
after washing the motorcycle and
riding in the rain.
1. To prevent damaging the O-rings,
do not clean the drive chain with
steam cleaners, high-pressure
washers or inappropriate sol-
vents. NOTICE: To prevent
damaging the O-rings, do not
clean the drive chain with ste-
am cleaners, high-pressure
washers or inappropriate sol-
vents.

Troubleshooting
Although Yamaha motorcycles recei-
ve a thorough inspection before ship-
ment 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 motorcy-
cle require any repair, take it to a
Yamaha dealer, whose skilled techni-
cians have the necessary tools, expe-
rience, and know-how to service the
motorcycle properly.
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.
EWA15141
When checking the fuel system, do
not smoke, and make sure there
are no open flames or sparks in the
area, including pilot lights from
water heaters or furnaces. Gasoli-
ne or gasoline vapors can ignite or
explode, causing severe injury or
property damage.
