5-OPERATION AND IMPORTANT RIDING POINTS
EAU00373
WARNING
_
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.
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.
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.
_
EAU04912
Starting the engine In order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:
The transmission is in the neutral
position.
The transmission is in gear with
the clutch lever pulled and the
sidestand up.
EW000054
WARNING
_
Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure
described on page 3-26.
Never ride with the sidestand
down.
_1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “”.
ECA00132
CAUTION:_ The following warning lights and in-
dicator light should come on for a
few seconds, then go off.
Oil level warning light
Fuel level warning light
Coolant temperature warning
light
Engine speed indicator light
Engine trouble warning light
If a warning or indicator light does
not go off, see pages 3-3–3-5 for the
corresponding warning and indica-
tor light circuit check.
_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. Start the engine by pushing the
start switch.

EAU02937
Recommended shift points
(for Switzerland only) The recommended shift points during
acceleration are shown in the table be-
low.CF-02ENOTE:_ 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). _
EAU04754
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 shift-
ing 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 traf-
fic lights or at railroad crossings).
EAU01128
Engine break-in There 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 annual checks must be performed every year, except if a kilometer-based maintenance is performed instead.
From 50,000 km, repeat the maintenance intervals starting from 10,000 km.
Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and techni-
cal skills.

615. Install the radiator cap and the
coolant reservoir cap, and then
start the engine and let it idle for
several minutes. During this peri-
od, rev the engine two or three
times between 3,000–5,000 r/min,
and then turn it off.
16. Remove the radiator cap to check
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.
17. 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.
18. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.
19. Install the cowlings and the panel.
EAU04572*
Replacing the air filter
element The air filter element should be re-
placed at the intervals specified in the
periodic maintenance and lubrication
chart. Replace the air filter element
more frequently if you are riding in un-
usually wet or dusty areas.
1. Remove the rider seat. (See page
3-17 for rider seat removal and in-
stallation procedures.)
2. Remove the bolt.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!)
EW000071
WARNING
_
Make sure that the fuel tank is
well supported.
Do not tilt or pull the fuel tank
too much, otherwise the fuel
hoses may come loose, which
could cause fuel leakage.
_4. Disconnect the fuel tank breather
hose and the fuel tank overflow
hose.

hose and the fuel tank overflow
hose, place the fuel tank in the
original position, and then install
the bolt.
EWA00067
WARNING
_
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.
Make sure that the fuel hoses
are properly connected and
routed, and not pinched.
Be sure to place the fuel tank
breather hose and the fuel tank
overflow hose in the original po-
sition.
_10. Install the rider seat.
EAU04578
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.
The engine should be warm before
making this adjustment.NOTE:_ The engine is warm when it quickly re-
sponds to the throttle. _

necessary, adjust it to specification by
turning the throttle stop screw. To in-
crease the engine idling speed, turn the
screw in direction
a. To decrease the
engine idling speed, turn the screw in
direction
b.
NOTE:_ If the specified idling speed cannot be
obtained as described above, have a
Yamaha dealer make the adjustment. _

Adjusting the throttle cable
free play The throttle cable free play should
measure 3–5 mm at the throttle grip.
Periodically check the throttle cable
free play and, if necessary, have a
Yamaha dealer adjust it.
EAU00637
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.

Replacing the fuses The main fuse and the electronic fuel
injection fuse are located under the rid-
er seat. (See page 3-17 for rider seat
removal and installation procedures.)
The fuse box, which contains the fuses
for the individual circuits, is located un-
der panel B. (See page 6-7 for panel
removal and installation procedures.)
If a fuse is blown, replace it as follows.
1. Turn the key to “OFF” and turn off
the electrical circuit in question.2. Remove the blown fuse, and then
install a new fuse of the specified
amperage.
EC000103
CAUTION:_ Do not use a fuse of a higher amper-
age rating than recommended to
avoid causing extensive damage to
the electrical system and possibly a
fire. _3. Turn the key to “ON” and turn on
the electrical circuit in question to
check if the device operates.
4. If the fuse immediately blows
again, have a Yamaha dealer
check the electrical system.

Troubleshooting Although Yamaha motorcycles receive
a thorough inspection before shipment
from the factory, trouble may occur dur-
ing 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 motorcycle
require any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, 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. U5PWE1.book Page 45 Monday, July 8, 2002 10:28 AM
