9Owners are personally responsible for their vehicle’s condition. Your motorcycle’s vital functions can start to
deteriorate quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements).
Any damage, fluid leak or loss of tire pressure could have serious consequences. Therefore, it is very important
that, in addition to a thorough visual inspection, you check the following points before each ride.

1. Before 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.
2. Never 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.
Always operate your motorcy-
cle in an area with adequate
ventilation.
3. Before starting out, always be
sure the sidestand is up.
Failure to retract the sidestand
completely can result in a seri-
ous accident when you try to
turn a corner.

the start switch or by kicking
the kick starter.
NOTE:
If the engine fails to start, release
the start switch, wait a few sec-
onds, then try again. Each attempt

the engine more than 10 seconds
on any one attempt. If the engine
does not start with the starter
motor, kick the kick starter to start
the engine.
6. After starting the engine, move
the starter to the halfway posi-
tion.
NOTE:
For maximum engine life, always
warm up the engine before starting
off. Never accelerate hard with a
cold engine.
7. After warming up the engine,
turn off the starter completely.
NOTE:
The engine is warm when it
responds normally to the throttle

Shifting
The transmission lets you control
the amount of power you have
available at a given speed for start-
ing, 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 reach-
es the end of its travel, then raise
the pedal slightly.
EC000048
cC
1. Do not coast for long periods
with the engine off, and do
not tow the motorcycle a long
distance. Even with gears in
neutral, the transmission is
only properly lubricated when
the engine is running.
Inadequate lubrication may
damage the transmission.
2. Always 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.

94. 1,000 km and beyond:
Avoid prolonged full-throttle
operation. Vary speed occa-
sionally.
EC000049
cC
If any engine trouble should occur
during the break-in period, consult
a Yamaha dealer immediately.
EAU00436Engine break-in
There is never a more important
period in the life of your motorcy-
cle than the period between zero
and 1,000 km. For this reason we
ask that you carefully read the fol-
lowing material. Because the
engine is brand new, you must not
put an excessive load on it for the
first 1,000 km. The various parts in
the engine wear and polish them-
selves to the correct operating
clearances. During this period, pro-
longed full throttle operation, or
any condition which might result in
excessive heating of the engine,
must be avoided.
EAU00446
1. 0 ~ 150 km:
Avoid operation above 1/3
throttle. Stop the engine and
let it cool for 5 to 10 minutes
after every hour of operation.
Vary the speed of the motorcy-
cle from time to time. Do not
operate it at one set throttle
position.
2. 150 ~ 500 km:
Avoid prolonged operation
above 1/2 throttle. Rev the
motorcycle freely through the
gears, but do not use full throt-
tle at any time.
3. 500 ~ 1,000 km:
Avoid cruising speeds in
excess of 3/4 throttle.
EC000057
cC
After 1,000 km of operation, be
sure to replace the engine oil and
clean the oil filter element and oil
strainer.

The exhaust system is hot. Park
