Periodic Maintenance Procedures
Measure the gap [A] with a wire-type thickness gauge.
If the gap is incorrect, carefully bend the side electrode
[B] with a suitable tool to obtain the correct gap.
Spark Plug Gap
0.6 ∼ 0.7 mm (0.024 ∼ 0.028 in.)
Install the spark plug.
Torque - Spark Plug: 13 N·m (1.3 kgf·m, 115 in·lb)
Insert the plug cap, and confirm for the spark plug not to
Battery Charging Condition Inspection
Battery charging condition can be checked by measuring
battery terminal voltage with a digital voltmeter [A].
Left Side Cover (see Side Cover Removal in the Frame
Seat (see Seat Removal in the Frame chapter)
Open the battery cover (see Battery Removal in the Elec-
trical System chapter).
Disconnect the battery terminals.
Be sure to disconnect the negative (–) cable first.
Measure the battery terminal voltage.
Measure with a digital voltmeter which can be read one
decimal place voltage.
If the reading is 12.6 V or more, no refresh charge is re-
quired, however, if the read is below the specified, refresh
charge is required.

12.6 V or more
Terminal Voltage (V) [A]
Battery Charge Rate (%) [B]
Refresh charge is required [C]
Battery Terminals Inspection
Check the battery terminal screws [A] for tightness and
make sure the terminal cover is in place.
Loose battery cables can create sparks which can
cause a fire or explosion resulting in injury or death.
Make sure the battery terminal screws are tightened
securely and the covers are installed over the termi-
