WARNING
lBefore riding this motorcycle,
become thoroughly familiar
with all operating controls and
their functions. Consult a
Yamaha dealer regarding any
control or function that you do
not thoroughly understand.
lNever start your engine or let it
run for any length of time in a
closed area. The exhaust fumes
are poisonous and can cause
loss of consciousness and
death within a short time. Al-
ways operate your motorcycle
in an area with adequate venti-
lation.
lBefore starting out, always be
sure the sidestand is up. Fail-
ure to retract the sidestand
completely can result in a seri-
ous accident when you try to
turn a corner.

the engine stop switch to “ ”.
ECA00005
CAUTION:
The warning light and fuel indicator
light should come on for a few sec-
onds and then go off. If an indicator
light does not go off, refer to the cor-
responding indicator light circuit
check in the “INSTRUMENT AND
CONTROL FUNCTIONS” section.
2. Shift the transmission into neutral.
NOTE:
When the transmission is in neutral, the
neutral indicator light should be on. If
the light does not come on, ask a
Yamaha dealer to inspect it.
3. Turn on the starter (choke) and
completely close the throttle grip.
4. Start the engine by pushing the
start switch.
NOTE:
If the engine fails to start, release the
start switch, wait a few seconds, then
try again. Each attempt should be as
short as possible to preserve the bat-
tery. Do not crank the engine more
than 10 seconds on any one attempt.5. After starting the engine, move
the starter (choke) to the halfway
position.
NOTE:
For maximum engine life, never accel-
erate hard with a cold engine!
6. After the engine is warm, turn off
the starter (choke) completely.
NOTE:
The engine is warm when it responds
normally to the throttle with the starter
(choke) turned off.
EAU01258
Starting a warm engine
The starter (choke) is not required
when the engine is warm.

Shifting
The transmission lets you control the
amount of power you have available at
a given speed for starting, accelerating,
climbing hills, etc. The use of the shift
pedal is shown in the illustration.
To shift into neutral, depress the shift
pedal repeatedly until it reaches the
end of its travel, then raise the pedal
slightly.
EC000048
CAUTION:
lDo not coast for long periods
with the engine off, and do not
tow the motorcycle a long dis-
tance. Even with gears in neu-
tral, the transmission is only
properly lubricated when the
engine is running. Inadequate
lubrication may damage the
transmission.
lAlways use the clutch when
changing gears. The engine,
transmission, and driveline are
not designed to withstand the
shock of forced shifting and
can be damaged by shifting
without using the clutch.

EAU01128
Engine break-in
There is never a more important period
in the life of your motorcycle than the
period between zero and 1,600 km. For
this reason we ask that you carefully
read the following material. Because
the engine is brand new, you must 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 which might re-
sult in excessive heating of the engine,
must be avoided.
EAU013290 ~ 1,000 km
Avoid operation above 5,500 r/min.
1,000 ~ 1,600 km
Avoid cruising speeds in excess of
7,000 r/min.
EC000052
CAUTION:
After 1,000 km of operation, be sure
to replace the engine oil and oil fil-
ter.
1,600 km and beyond
Proceed with normal riding.
EC000053
CAUTION:
lNever let engine speeds enter
the red zone.
lIf any engine trouble should oc-
cur during the break-in period,
consult a Yamaha dealer imme-
diately.
EAU00460
Parking
When parking the motorcycle, stop the
engine and remove the ignition key.
EW000058
WARNING
The exhaust system is hot. Park the
motorcycle in a place where pedes-
trians or children are not likely to
touch the motorcycle. Do not park
the motorcycle on a slope or soft
ground; the motorcycle may over-
turn.
INCLUDED ACCESSORIES
EAU01575
Tool kit
The tools provided in the owner’s tool
kit are to assist you in the performance
of periodic maintenance. However,
some other tools such as a torque
wrench are also necessary to perform
the maintenance correctly.
The service information included in this
manual is intended to provide you, the
owner, with the necessary information
for completing some of your own pre-
ventive maintenance and minor re-
pairs.
NOTE:
If you do not have necessary tools re-
quired during a service operation, take
your motorcycle to a Yamaha dealer
for service.
EW000063
WARNING
Modifications to this motorcycle not
approved by Yamaha may cause
loss of performance, and render it
unsafe for use. Consult a Yamaha
dealer before attempting any chang-
es.

MOTORCYCLE CARE AND STORAGE
1. Clean your motorcycle with cold
water and soap after the engine
has cooled down.
ECA00012
CAUTION:
Do not use warm water since it in-
creases the corrosive action of the
salt.
2. Be sure to apply a corrosion pro-
tection spray on all (even chrome-
and nickel-plated) metal surfaces
to prevent corrosion.After cleaning
1. Dry the motorcycle with a cham-
ois or an absorbing cloth.
2. Immediately dry the drive chain
and lubricate it to prevent it from
rusting.
3. Use a chrome polish to shine
chrome, aluminum and stainless-
steel parts, including the exhaust
system. (Even the thermally in-
duced discoloring of stainless-
steel exhaust systems can be re-
moved through polishing.)
4. To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all (even chrome-
and nickel-plated) metal surfaces.
5. Use spray oil as a universal clean-
er to remove any remaining dirt.
6. Touch up minor paint damage
caused by stones, etc.
7. Wax all painted surfaces.
CAUTION:
Do not wax the frame, swingarm and
other similar matte metal parts, as
this may deteriorate their finish.
8. Let the motorcycle dry completely
before storing it or covering it.
EWA00001
WARNING
Make sure that there is no oil or wax
on the brakes and tires. If necessary,
clean the brake discs and linings
with a regular brake disc cleaner or
acetone, and wash the tires with
warm water and mild soap. Then,
carefully test the motorcycle for its
braking performance and cornering
behavior.
ECA00013
CAUTION:
lApply spray oil and wax spar-
ingly and wipe off any excess.
lNever apply oil or wax on rub-
ber and plastic parts, but treat
them with a suitable care prod-
uct.
lAvoid using abrasive polishing
compounds as they wear away
the paint.
NOTE:
Consult a Yamaha dealer for advice on
what products to use.
Storage
Short-term
Always store your motorcycle in a cool,
dry place and, if necessary, protect it
against dust with a porous cover.
ECA00014
CAUTION:
lStoring the motorcycle in a
poorly ventilated room or cov-
ering it with a tarp while it is still
wet will allow water and humid-
ity to seep in and cause rust.
lTo prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-
cals are stored.Long-term
Long term storage (60 days or more) of
your motorcycle will require some pre-
ventive procedures to guard against
deterioration. After throughly cleaning
the motorcycle, prepare for storage as
follows:
1. Drain the fuel tank.
2. Remove the empty fuel tank, pour
a cup of engine oil in the tank,
shake the tank to coat the inner
surfaces thoroughly and drain off
the excess oil. Reinstall the tank.
3. Remove the spark plug, pour
about one tablespoon of engine
oil in the spark plug hole and rein-
stall the spark plug. Turn the en-
gine over several times (ground
spark plug lead wires) to coat the
cylinder walls with oil.
