INITIAL CHARGING

FILLING ELECTROLYTE

• Remove the aluminum tape 

 

1

 sealing the battery electrolyte

filler holes 

 

2

.

• Remove the caps 

 

3

.

NOTE:
* After filling the electrolyte completely, use the removed caps

 

3

 as the sealed caps of battery filler holes.

* Do not remove or pierce the sealed areas 

 

4

 of the electrolyte

container.

• Insert the nozzles of the electrolyte container 

 

5

 into the bat-

tery’s electrolyte filler holes, holding the container firmly so
that it does not fall. Take precaution not to allow any of the
fluid to spill.

• Make sure air bubbles 

 

6

 are coming up each electrolyte con-

tainer, and leave in this position for about more than 20 min-
utes.

ELECTRICAL SYSTEM     8-35

NOTE:
If on air bubbles are coming up from a filler port, tap the bottom
of the electrolyte container two or three times.
Never remove the container from the battery.

• After confirming that the electrolyte has entered the battery

completely, remove the electrolyte containers from the bat-
tery. Wait for about more than 20 minutes.

• Insert the caps 

 

2

 into the filler holes, pressing in firmly so that

the top of the caps do not protrude above the upper surface of
the battery’s top cover.

"

• For initial charging, use the charger specially designed for MF

battery.

"

SERVICING

Visually inspect the surface of the battery container. If any signs
of cracking or electrolyte leakage from the sides of the battery
have occurred, replace the battery with a new one. If the battery
terminals are found to be coated with rust or an acidic white
powdery substance, clean the battery terminals with sandpaper.

* Never use anything except the specified battery.
* Once install the caps to the battery; do not remove

the caps.

* Do not tap the caps with a hammer when installing

them.

CORRECT

INCORRECT

* For charging the battery, make sure to use the

charger specially designed for MF battery. Other-
wise, the battery may be overcharged resulting in
shortned service life.

* Do not remove the cap during charging.
* Position the battery with the cap facing upward dur-

ing charging.

RECHARGING OPERATION

• Measure the battery voltage using the multi circuit tester. If

the voltage reading is less than the 12 V (DC), recharge the
battery with a battery charger.

"

NOTE:
While recharging, do not remove the caps on the top of the bat-
tery.

Recharging time: 1.2 A for 5 to 10 hours or 5 A for 1 hour.

"

• After recharging, wait at least 30 minutes and then measure

the battery voltage using the multi circuit tester. If the battery
voltage is less than 12.5 V, recharge the battery again. If the
battery voltage is still less than 12.5 V after recharging,
replace the battery with a new one.

• When a battery is left unused for a long time, its voltage

needs to be regularly measured. When the motorcycle is not
used for more than one month (especially during the winter
season), measure the battery voltage at least once a month.

BATTERY REMOVAL

• Open the front trunk.
• Remove the battery cover
