Battery A poorly maintained battery will cor-
rode and discharge quickly. The elec-
trolyte level, battery lead connections
and breather hose routing should be
checked before each ride and at the in-
tervals specified in the periodic mainte-
nance and lubrication chart.To check the electrolyte level
1. Place the motorcycle on a level
surface and hold it in an upright
position.
NOTE:@ Make sure that the motorcycle is posi-
tioned straight up when checking the
electrolyte level. @2. Check the electrolyte level in the
battery.NOTE:@ The electrolyte should be between the
minimum and maximum level marks. @
3. If the electrolyte is at or below the
minimum level mark, add distilled
water to raise it to the maximum
level mark.
EW000116
WARNING
@ l
Electrolyte is poisonous and
dangerous since it contains sul-
furic acid, which causes severe
burns. Avoid any contact with
skin, eyes or clothing and al-
ways shield your eyes when
working near batteries. In case
of contact, administer the fol-
lowing FIRST AID.
• EXTERNAL: Flush with plenty
of water.
• INTERNAL: Drink large quan-
tities of water or milk and im-
mediately call a physician.
• EYES: Flush with water for
15 minutes and seek prompt
medical attention.

EC000100
CAUTION:@ Use only distilled water, as tap water
contains minerals that are harmful
to the battery. @4. Check and, if necessary, tighten
the battery lead connections and
correct the breather hose routing.
To store the battery
1. If the motorcycle will not be used
for more than one month, remove
the battery, fully charge it, and
then place it in a cool, dry place.2. If the battery will be stored for
more than two months, check the
specific gravity of the electrolyte at
least once a month and fully
charge the battery whenever
necessary.
3. Fully charge the battery before
installation.
4. After installation, make sure that
the battery leads are properly con-
nected to the battery terminals and
that the breather hose is properly
routed, in good condition, and not
obstructed.
EC000099
CAUTION:@ If the breather hose is positioned in
such a way that the frame is ex-
posed to electrolyte or gas expelled
from the battery, the frame could
suffer structural and external
damages. @
