4-PRE-OPERATION CHECKS
The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspec-
tion, to check the following points before each ride.

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.
For safety, always start the en-
gine with the centerstand.
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.

cold engine
EC000046
CAUTION:_ See page 5-4 for engine break-in in-
structions prior to operating the ve-
hicle for the first time. _1. Turn the key to “ON”.
2. Turn on the starter (choke) and
completely close the throttle grip.
(See page 3-6 for starter (choke)
operation.)3. Start the engine by pushing the
start switch, while applying the
front or rear brake or by pushing
the kickstarter lever down.
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 5 seconds on any one
attempt. If the engine does not start
with the starter motor, try using the
kickstarter with the motorcycle on the
centerstand. _

54. After starting the engine, move the
starter (choke) back about half-
way.
ECA00055
CAUTION:_ For maximum engine life, always
warm the engine up before starting
off. Never accelerate hard when the
engine is cold! _5. When the engine is warm, turn the
starter (choke) off.NOTE:_ For maximum engine life, always warm
up the engine before riding your motor-
cycle. Never accelerate hard with a
cold engine. _
EAU01258
Starting a warm engine Follow the same procedure as for start-
ing a cold engine with the exception
that the starter (choke) is not required
when the engine is warm.
EAU00433*
Starting off NOTE:_ Before starting off, allow the engine to
warm up. _1. While pulling the rear brake lever
with your left hand and holding the
grab bar with your right hand, push
the motorcycle off the centerstand.
2. Sit astride the seat, and then ad-
just the rear view mirrors.
3. Switch the turn signal on.
4. Check for oncoming traffic, and
then slowly turn the throttle grip
(on the right) in order to take off.
5. Switch the turn signal off.

EAU00436
Engine break-in There is never a more important period
in the life of your engine than the period
between 0 and 1,000 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
1,000 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.
EAU00447*
0–150 km
Avoid prolonged operation above
1/3 throttle.
After every hour of operation, stop
the engine, and then let it cool for
five to ten minutes.
Vary the engine speed from time
to time. Do not operate the engine
at one set throttle position.
150–500 km
Avoid prolonged operation above
1/2 throttle.
Rev the engine freely through the
gears, but do not use full throttle at
any time.
EC000058*
CAUTION:_ After 500 km of operation, the en-
gine oil and the final transmission
oil must be changed and the engine
oil strainer cleaned. _
500–1,000 km
Avoid prolonged operation above
3/4 throttle.
1,000 km and beyond
Avoid prolonged full-throttle operation.
Vary the speed occasionally.
EC000049
CAUTION:_ If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle. _

WARNING
_
Since the engine and exhaust
system can become very hot,
park in a place where pedestri-
ans or children are not likely to
touch them.
Do not park on a slope or on
soft ground, otherwise the
motorcycle may overturn.

* Since these items require special tools, data and technical skills, have a Yamaha dealer perform the service.
EAU03057*
NOTE:_
From 16,000 km, repeat the maintenance intervals starting from 4,000 km.
Depending on riding conditions, the V-belt replacement interval may vary.
The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
Hydraulic brake system
After disassembling the brake master cylinder, and caliper cylinder, always change the fluid. Regularly check the
brake fluid level and fill reservoir as required.
Replace the oil seals on the inner parts of the brake master cylinder and caliper cylinder every two years.
Replace the brake hose every four years or if cracked or damaged.

Checking the spark plug The spark plug is an important engine
component, which is easy to check.
Since heat and deposits will cause any
spark plug to slowly erode, the spark
plug should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plug can re-
veal the condition of the engine.
To remove the spark plug
1. Remove panel A. (See page 6-4
for panel removal and installation
procedures.)
2. Remove the spark plug cap.3. Remove the spark plug as shown,
with the spark plug wrench includ-
ed in the owner’s tool kit.To check the spark plug
1. Check that the porcelain insulator
around the center electrode of the
spark plug is a medium-to-light tan
(the ideal color when the motor-
cycle is ridden normally).
NOTE:_ If the spark plug shows a distinctly dif-
ferent color, the engine could be defec-
tive. Do not attempt to diagnose such
problems yourself. Instead, have a
Yamaha dealer check the motorcycle. _2. Check the spark plug for electrode
erosion and excessive carbon or
other deposits, and replace it if
necessary.
