NOTE:@ If the engine fails to start, release the
start switch, wait a few seconds, and
then try again. Each starting attempt
should be as short as possible to pre-
serve the battery. Do not crank the en-
gine more than 10 seconds on any one
attempt. @
EC000038
CAUTION:@ l
The oil level warning light and
fuel level warning light should
come on when the start switch
is pushed, and they should go
off when the start switch is
released.
l
If the oil level warning light flick-
ers or remains on after starting,
immediately stop the engine,
and then check the engine oil
level and the vehicle for oil leak-
age. If necessary, add engine
oil, and then check the warning
light again. If the warning light
does not come on when push-
ing the start switch, or if it doesnot go off after starting with suf-
ficient engine oil, have a
Yamaha dealer check the elec-
trical circuit.
l
If the fuel level warning light re-
mains on after starting, stop the
engine, and then check the fuel
level. If necessary, refuel as
soon as possible, and then
check the warning light again. If
the warning light does not come
on when pushing the start
switch, or if it does not go off af-
ter starting with sufficient fuel,
have a Yamaha dealer check the
electrical circuit.
@5. After starting the engine, move the
starter (choke) lever back halfway.
ECA00045
CAUTION:@ For maximum engine life, never ac-
celerate hard when the engine is
cold! @
6. When the engine is warm, turn the
starter (choke) off.NOTE:@ l
The engine is warm when it re-
sponds normally to the throttle
with the starter (choke) turned off.
l
When the engine is idling with the
starter (choke) turned on, the radi-
ator fan will automatically be
switched on and off regardless of
the coolant temperature. As a re-
sult, the engine idling speed will
vary, but this does not indicate a
malfunction.

EAU00464
Safety is an obligation of the owner.
Periodic inspection, adjustment and lu-
brication 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
SHORTENED.

@ If you are not familiar with motor-
cycle maintenance work, have a
Yamaha dealer do it for you. @

compartment under the passenger
seat. (See page 3-14 for passenger
seat removal procedures.)
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. @

then tighten it to the specified
torque.10. Add the specified amount of the
recommended engine oil, and
then install and tighten the oil filler

EC000072
CAUTION:@ l
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives with
the oil or use oils of a higher
grade than “CD”. In addition, do
not use oils labeled “ENERGY
CONSERVING II” or higher.
l
Make sure that no foreign mate-
rial enters the crankcase.
@11. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.NOTE:@ After the engine is started, the engine

Adjusting the carburetors The carburetors are important parts of
the engine and require very sophisti-
cated adjustment. Therefore, most car-
buretor adjustments should be left to a
Yamaha dealer, who has the neces-
sary professional knowledge and expe-
rience. The adjustment described in
the following section, however, may be
serviced by the owner as part of routine
maintenance.
EC000095
CAUTION:@ The carburetors have been set and
extensively tested at the Yamaha
factory. Changing these settings
without sufficient technical knowl-
edge may result in poor perfor-
mance of or damage to the engine. @

Adjusting the 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.

TiresTo maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points
regarding the specified tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
EW000082
WARNING
@ l
The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperature
of the tires equals the ambient
temperature).
l
The 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.
