STARTING AND OPERATION
STARTING AND OPERATION
CAUTION:
Prior to operating the machine, perform
steps listed in pre-operation check list.
WARNING
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 machine in an
area with adequate ventilation.
STARTING A COLD ENGINE
WARNING
Before starting the engine, be sure to shift
the transmission into neutral.
NOTE:
 This model is equipped with an ignition cir-
cuit cut-off system. In case of electric start-
ing, the engine can be started only when the
transmission is in neutral.
 If the engine fails to start by pushing the start
switch, release the switch, wait a few sec-
onds, and then try again. Each starting
attempt should be as short as possible to
preserve the battery. Do not crank the
engine more than 10 seconds on any one
attempt.
1. Turn the fuel cock to “ON ”.
2. Turn the main switch to “ON ”.
3. Shift the transmission into neutral.
4. Operate the starter (choke) and completely close the throttle grip.
5. Slide the “engine stop ” switch to the “”.
6. Start the engine by pushing the start switch.
7. After the engine starts, warm up for one or
two minutes. Make sure the stater (choke) is
returned to the original position before riding. STARTING A WARM ENGINE
To start a warm engine, refer to the
“START-
ING A COLD ENGINE ” section. The starter
(choke) should not be used. The throttle
should be opened slightly.
CAUTION:
See “Engine break-in Section ” prior to
operating engine for the first time.
WARMING UP
To get maximum engine life, always “warm-up ”
the engine before starting off. Never accelerate
hard with a cold engine! To see whether or not
the engine is warm, see if it responds to throttle
normally with the stater (choke) turned off.
WARNING
Before starting off, be sure to turn up or
remove the side stand.
Failure to retract the side stand completely
can result in a serious accident when you
try to turn a corner.
ENGINE BREAK-IN
Break-in is important to better fit the moving
and sliding parts as well as the installed parts.
It is also important to accustom the rider to the
machine better.
Avoid full-throttle run on a new machine for the
first 5 hours.
After the trial run, check for loose parts, oil
leakage and other problems.
Make full inspection and adjustment especially of
slack cables and drive chain and loose spokes.
CAUTION:
After the break-in period, check every fit-
ting and fastener for looseness.
If any loose is found, retighten it securely.

SPECCABLE ROUTING DIAGRAM
ÒFasten the wire harness, AC magneto lead, and
starter motor lead to the frame with a plastic
locking tie at the location shown in the illustra-
tion. Cut off the excess end of the plastic locking
tie, and then face the cut end of the tie upward.
The cut end of the plastic locking tie should be
5 mm (0.20 in) or less.
Ó Gather the slack of the AC magneto lead and
starter motor lead in the area shown in the illus-
tration, and then place the slack between the air
filter case and battery. Ô
Pass the brake cable through the guides on the
front fork guard.
Õ Do not fasten the rectifier/regulator lead.
Ö Do not pinch the starter motor lead.
× Before installing the CDI unit, connect the AC
magneto lead couplers and place them under
the wire harness in the CDI unit holder.
Ø Place the cover on the CDI unit, and then install
the CDI unit in the CDI unit holder.

BATTERY INSPECTION AND CHARGING
WARNING
Batteries generate explosive hydrogen gas
and contain electrolyte which is made of
poisonous and highly caustic sulfuric acid.
Therefore, always follow these preventive
measures:
 Wear protective eye gear when handling
or working near batteries.
 Charge batteries in a well-ventilated area.
 Keep batteries away from fire, sparks or
open flames (e.g., welding equipment,
lighted cigarettes).
 DO NOT SMOKE when charging or han-
dling batteries.
 KEEP BATTERIES AND ELECTROLYTE
OUT OF REACH OF CHILDREN.
 Avoid bodily contact with electrolyte as it
can cause severe burns or permanent eye
injury.
FIRST AID IN CASE OF BODILY CONTACT:
EXTERNAL
 Skin — Wash with water.
 Eyes — Flush with water for 15 minutes
and get immediate medical attention.
INTERNAL
 Drink large quantities of water or milk fol-
lowed with milk of magnesia, beaten egg
or vegetable oil. Get immediate medical
attention.
CAUTION:
Charging time, charging amperage and
charging voltage for an MF battery are dif-
ferent from those of conventional batteries.
The MF battery should be charged as
explained in the charging method illustra-
tions. If the battery is overcharged, the
electrolyte level will drop considerably.
Therefore, take special care when charging
the battery.

INSPADJ
BATTERY INSPECTION AND CHARGING
NOTE:
Since MF batteries are sealed, it is not possi-
ble to check the charge state of the battery by
measuring the specific gravity of the electro-
lyte. Therefore, the charge of the battery has to
be checked by measuring the voltage at the
battery terminals.
1. Remove:
Seat assembly
 Battery cover
Refer to “FRONT FENDER, SEAT
ASSEMBLY AND FUEL TANK ” section in
the CHAPTER 4.
2. Disconnect:
Battery lead coupler 1
(from the battery terminals)
NOTE:
Push down on the tab a, and then remove the
battery lead coupler.
3. Remove:
Battery band
 Battery
Refer to “FRONT FENDER, SEAT
ASSEMBLY AND FUEL TANK ” section in
the CHAPTER 4.

a
4. Measure:
Battery charge
Measurement steps:
 Connect a pocket tester 1 to the battery
terminals.
Tester positive probe → battery positive
terminal
Tester negative probe → battery negative
terminal
NOTE:
 The charge state of an MF battery can be
checked by measuring its open-circuit volt-
age (i.e., the voltage when the positive ter-
minal is disconnected).
 No charging is necessary when the open-
circuit voltage equals or exceeds 12.8 V.

5. Charge: Battery
(refer to the appropriate charging method
illustration)
WARNING
Do not quick charge a battery.
CAUTION:
 Never remove the MF battery sealing
caps.
 Do not use a high-rate battery charger
since it forces a high-amperage current
into the battery quickly and can cause
battery overheating and battery plate
damage.
 If it is impossible to regulate the charging
current on the battery charger, be careful
not to overcharge the battery.
