NOTE:
Pre-operation checks should be made each time the motorcycle is used. Such an inspection can be accom-
plished in a very short time; and the added safety it assures is more than worth the time involved.
w
If any item in the Pre-Operation Check is not working properly, have it inspected and repaired before operating
the motorcycle.

91. Turn the fuel cock to “ON”.
2. Turn the main switch to “ON”
and the engine stop switch to
“#”.
3. Shift the transmission into
neutral.
NOTE:
When the transmission is in neu-
tral, 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 sec-
onds, then try again. Each attempt
should be as short as possible to
preserve the battery. Do not crank
the engine more than 10 seconds
on any one attempt.
6. After starting the engine, move
the starter (choke) to the
halfway position.
NOTE:
For maximum engine life, never
accelerate hard with a cold engine!
7. After warming up the engine,
turn off the starter (choke)
completely.
NOTE:
The engine is warm when it
responds normally to the throttle
with the starter (choke) turned off.
EAU01258Starting a warm engine
The starter (choke) is not required
when the engine is warm.

Securely support the motorcycle
so there is no danger of it falling
over.

Replenishing the battery fluid
A poorly maintained battery will
corrode and discharge quickly. The
battery fluid should be checked at
least once a month. The level
should be between the minimum
level and maximum level marks.
Use only distilled water if refilling
is necessary.

When inspecting the battery, be
sure the breather hose is routed
correctly. If the breather hose is
positioned in such a way as to
cause battery electrolyte or gas to
exit onto the frame, structural and
cosmetic damage to the motorcy-
cle can occur.
EW000116
w
Battery electrolyte is poisonous
and dangerous, causing severe
burns, etc. It contains sulfuric acid.
Avoid contact with skin, eyes or
clothing.
ANTIDOTE:
8EXTERNAL: Flush with water.
8INTERNAL: Drink large quanti-
ties of water or milk. Follow
with milk of magnesia, beaten
egg, or vegetable oil. Call a
physician immediately.
8EYES: Flush with water for 15
minutes and get prompt med-
ical attention.
Batteries produce explosive gases.
Keep sparks, flame, cigarettes etc.,
away. Ventilate when charging or
using in an enclosed space.
Always shield your eyes when
working near batteries.
KEEP OUT OF REACH OF CHIL-
DREN.

Normal tap water contains miner-
als which are harmful to a battery;
therefore, refill only with distilled
water.

Take care not to spill battery fluid
on the chain. Battery fluid may
weaken the chain causing shorter
chain life and possibly result in an
accident.
Battery storage
8When the motorcycle will not
be used for a month or longer,
remove the battery, fully
charge it and store it in a cool,
dry place. Completely recharge
the battery before reinstalla-
tion.
8If the battery will be stored for
longer than two months, check
the specific gravity of the fluid
at least once a month and fully
recharge the battery when it is
too low.
8Always make sure the connec-
tions are correct when putting
the battery back in the motor-
cycle. Make sure the breather
hose is properly connected
and is not damaged or
obstructed.
EAU01073Fuse replacement
The fuse cases are located under
the rider seat.
If a fuse is blown, turn off the main
switch and the switch of the circuit
in question. Install a new fuse of
specified amperage. Turn on the
switches and see if the electrical
device operates. If the fuse imme-
diately blows again, consult a
Yamaha dealer.
