OPERATION AND IMPORTANT RIDING POINTS/
INCLUDED ACCESSORIES
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.

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.

MOTORCYCLE CARE AND STORAGE/
CONSUMER INFORMATION
WARNING
When using the starter motor to
crank the engine, remove the spark
plug wires, and ground them to pre-
vent sparking.
4. Remove the drive chain. Thor-
oughly clean the chain with kero-
sene and lubricate it. Reinstall the
chain or store it in a plastic bag
(tied to frame for safekeeping).
5. Lubricate all control cables.
6. Block up the frame to raise both
wheels off the ground.
7. Tie a plastic bag over the exhaust
pipe outlet to prevent moisture
from entering.
8. If strong in a humid or salt-air at-
mosphere, coat all exposed metal
surfaces with a light film of oil. Do
not apply oil to any rubber parts or
the seat cover.9. Remove the battery and charge it.
Store it in a dry place and re-
change it once a month. Do not
store the battery in an excessively
warm or cold place (less than 0°C
(30°F) or more than 30°C (90°F)).
NOTE:
Make any necessary repairs before
storing the motorcycle.

5. Engine overheatingEW000070
WARNING
Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be blown out
under pressure, which could cause serious injury. Open the radiator cap as follows. Wait until the engine has
cooled. Remove the radiator cap stopper by removing the screw. Place a thick rag like a towel over the radiator cap
and slowly rotate the cap counterclockwise to the detent. This procedure allows any residual pressure to escape.
When the hissing sound has stopped, press down on the cap while turning counterclockwise and remove it.
NOTE:
If it is difficult to get the recommended coolant, tap water can be temporarily used, provided that it is changed to the recom-
mended coolant as soon as possible.
Wait until the
engine has cooled.Check the coolant level in the
reservoir tank and/or radiator.
Level is OK.
Level is low, check the
cooling system for leakage.
No
leakage.
Leakage.Ask a Yamaha dealer to inspect
and repair the cooling system.
Add coolant. (See NOTE.)
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and repair the cooling system.

MEASURING THE COMPRESSION PRESSURE
WARNINGWARNING
To prevent sparking, ground all spark
plug leads before cranking the engine.
NOTE:
The difference in compression pressure
between cylinders should not exceed
100 kPa (1 kg/cm2, 14 psi).
c. If the compression pressure is above
the maximum specification, check the
cylinder head, valve surfaces, and
piston crown for carbon deposits.
Carbon deposits ® Eliminate.
d. If the compression pressure is below
the minimum specification, squirt a
few drops of oil into the cylinder and
measure again.
Refer to the following table.
