5-OPERATION AND IMPORTANT RIDING POINTS
EAU00373
WARNING
@ l
Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer re-
garding any control or function
that you do not thoroughly un-
derstand.
l
Never start the engine or oper-
ate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of con-
sciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.
l
Before starting out, make sure
that the sidestand is up. If the
sidestand is not raised com-
pletely, it could contact the
ground and distract the opera-
tor, resulting in a possible loss
of control.

EAU03160
Starting a cold engine In order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:l
The transmission is in the neutral
position.
l
The transmission is in gear with
the clutch lever pulled and the
sidestand up.
EW000054
WARNING
@ l
Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure
described on page 3-24.
l
Never ride with the sidestand
down.
@1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “ ”.
EC000035
CAUTION:@ If the fuel level warning light comes
on, check the fuel level, and, if nec-
essary, refuel as soon as possible. @2. Shift the transmission into the neu-
tral position.NOTE:@ When the transmission is in the neutral
position, the neutral indicator light
should be on, otherwise have a
Yamaha dealer check the electrical cir-
cuit. @3. Turn the starter (choke) on and
completely close the throttle. (See
page 3-13 for starter (choke) oper-
ation.)
4. Start the engine by pushing the
start switch.

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 re-
leased.
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.

Recommended shift points
(for Switzerland only)The recommended shift points during
acceleration are shown in the table be-
low.CF-26ENOTE:@ When shifting down two gears at a
time, reduce the speed accordingly
(e.g., down to 35 km/h when shifting
from 5th to 3rd gear). @
EAU00424
Tips for reducing fuel
consumption Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:l
Thoroughly warm up the engine.
l
Turn the starter (choke) off as
soon as possible.
l
Shift up swiftly, and avoid high en-
gine speeds during acceleration.
l
Do not rev the engine while shift-
ing down, and avoid high engine
speeds with no load on the engine.
l
Turn 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).
EAU01128
Engine break-inThere is never a more important period
in the life of your engine than the period
between 0 and 1,600 km. For this rea-
son, you should read the following ma-
terial carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1,600 km. The various parts in the en-
gine wear and polish themselves to the
correct operating clearances. During
this period, prolonged full-throttle oper-
ation or any condition that might result
in engine overheating must be avoided.

the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the top of the radia-
tor, and then install the radiator
cap.
15. Check the coolant level in the res-
ervoir. If necessary, remove the
coolant reservoir cap, add coolant
to the maximum level mark, and
then install the cap.
16. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.
17. Install the cowlings and the panel.

Cleaning the air filter element The air filter element should be cleaned
at the intervals specified in the periodic
maintenance and lubrication chart.
Clean the air filter element more fre-
quently if you are riding in unusually
wet or dusty areas.
1. Remove the rider seat. (See page
3-14 for rider seat removal and in-
stallation procedures.)
2. Remove the bolt at the front of the
fuel tank and loosen the bolt at the
rear.3. Lift the front of the fuel tank, and
then tilt it back and away from the
air filter case. (Do not disconnect
the fuel hoses!)1. Bolt (front)

WARNING
@ l
Make sure that the fuel tank is
well supported.
l
Do not tilt or pull the fuel tank
too much, otherwise the fuel
hoses may come loose, which
could cause fuel leakage.
@4. Remove the air filter case cover by
removing the screws and bolt.5. Pull the air filter element out.
6. Lightly tap the air filter element to
remove most of the dust and dirt,
and then blow the remaining dirt
out with compressed air as shown.
If the air filter element is damaged,
replace it.
7. Insert the air filter element into the
air filter case.
EC000082
CAUTION:@ l
Make sure that the air filter ele-
ment is properly seated in the
air filter case.
l
The engine should never be op-
erated without the air filter ele-
ment installed, otherwise the
piston(s) and/or cylinder(s) may
become excessively worn.
@8. Install the air filter case cover by
installing the screws and bolt.
9. Place the fuel tank in the original
position, and then install the bolt at
the front and tighten the bolt at the
rear.

WARNING
@ l
Before installing the fuel tank,
make sure that the fuel hoses
are not damaged. If any fuel
hose is damaged, do not start
the engine but have a Yamaha
dealer replace the hose, other-
wise fuel may leak.
l
Make sure that the fuel hoses
are properly connected and
routed, and not pinched.

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. @
EAU00632
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 lubrication
chart.
1. Start the engine and warm it up for
several minutes at 1,000–
2,000 r/min while occasionally rev-
ving it to 4,000–5,000 r/min.NOTE:@ The engine is warm when it quickly re-
sponds to the throttle. @
