1. Turn the fuel cock to “ON”.
2. Turn the main switch to “ON” and
the engine stop switch to “#“.
3. Shift 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.
4. Turn on the starter (choke) and
completely close the throttle grip.
5. 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.

The oil level indicator light should
come on when the start switch is
pushed and should go off when
the start switch is released. If the
indicator light flickers or remains
on, immediately stop the engine
and check the engine oil level and
for oil leakage. If necessary, fill the
engine with oil and check to see
that the oil level indicator light
goes off. If the light does not go off
even with sufficient oil in the
crankcase or the light does not
come on when pushing the start
switch, consult a Yamaha dealer.
6. After starting the engine, move
the starter (choke) halfway back.
NOTE:
For maximum engine life, never
accelerate hard with a cold engine!
7. 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.

Tips for reducing fuel
consumption
Your motorcycle’s fuel consumption
depends to a large extent on your rid-
ing style. The following tips can help
reduce fuel consumption:
8Warm up the engine before rid-
ing.
8Turn off the starter (choke) as
soon as possible.
8Shift up swiftly and avoid high
engine speeds during accelera-
tion.
8Do not double-clutch or rev the
engine while shifting down and
avoid high engine speeds with
no load on the engine.
8Turn off the engine instead of let-
ting it idle for an extended length
of time, i.e. in traffic jams, at traf-
fic lights or railroad crossings.
EAU00436Engine break-in
There is never a more important peri-
od in the life of your motorcycle than
the period between zero and 1,000
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 1,000 km. The vari-
ous parts in the engine wear and pol-
ish themselves to the correct operat-
ing clearances. During this period,
prolonged full throttle operation, or
any condition which might result in
excessive heating of the engine,
must be avoided.

0 ~ 500 km
Avoid operation above 6,000 r/min.
Stop the engine and let it cool for 5 to
10 minutes after every hour of opera-
tion. Vary the speed of the motorcy-
cle from time to time. Do not operate
it at one set throttle position.
500 ~ 1,000 km
Avoid prolonged operation above
7,000 r/min. Rev the motorcycle
freely through the gears, but do not
use full throttle at any time.

Parking
When parking the motorcycle, stop
the engine and remove the ignition
key. Turn the fuel cock to “OFF”
whenever stopping the engine.
EW000058
w
The exhaust system is hot. Park
the motorcycle in a place where
pedestrians or children are not
likely to touch the motorcycle. Do
not park the motorcycle on a slope
or soft ground; the motorcycle
may overturn.
EC000062
cC
Never park this motorcycle in an
area that would cause a fire hazard
such as grass or other materials
that may easily burn.

nected, in place and not pinched. If
a hose is damaged, be sure to
replace it.
EAU00629Carburetor adjustment
The carburetor is a vital part of the
engine and requires very sophisticat-
ed adjustment. Most adjustments
should be left to a Yamaha dealer
who has the professional knowledge
and experience to do so. However,
the following may be serviced by the
owner as part of routine mainte-
nance.
EC000094
cC
The carburetor was set at the
Yamaha factory after many tests. If
the settings are changed, poor
engine performance and damage
may result.

1. Start the engine and warm it up
for a few minutes at approxi-
mately 1,000 to 2,000 r/min.
Occasionally rev the engine to
4,000 to 5,000 r/min. The engine
is warm when it quickly responds
to the throttle.
2. Set the idle to the specified
engine speed by adjusting the
throttle stop screw. Turn the
screw in direction ato increase
engine speed and in direction b
to decrease engine speed.

EAU01008Troubleshooting
Although Yamaha motorcycles
receive a rigid inspection before ship-
ment from the factory, trouble may
occur during operation.
Any problem in the fuel, compres-
sion, or ignition systems can cause
poor starting and loss of power. The
troubleshooting chart describes a
quick, easy procedure for making
checks.
If your motorcycle requires any
repair, bring it to a Yamaha dealer.
The skilled technicians at a Yamaha
dealership have the tools, experi-
ence, and know-how to properly ser-
vice your motorcycle. Use only gen-
uine Yamaha parts on your
motorcycle. Imitation parts may look
like Yamaha parts, but they are often
inferior. Consequently, they have a
shorter service life and can lead to
expensive repair bills.
