INSPECTION
IGNITION COIL PRIMARY PEAK VOLTAGE
• Remove the lower leg shield. (9-10)
• Remove the radiator mounting bolt.
• Disconnect the two ignition coil/plug caps.
• Connect the new spark plugs to the each ignition coil/plug cap
and ground them on the cylinder head.
NOTE:
Make sure that the each ignition coil/plug cap and spark plug are
connected properly.
Measure the ignition coil primary peak voltage using the multi
circuit tester in the following procedure.
• Connect the multi circuit tester with the peak volt adaptor as
follows.
No.1 ignition coil/plug cap:
+
Probe: White/Blue lead wire connector
-
Probe: Ground
No.2 ignition coil/plug cap:
+
Probe: Black/Yellow lead wire connector
-
Probe: Ground
NOTE:
Do not disconnect the ignition coil/plug cap lead wire couplers.

• Set the side-stand upright position, and then turn the ignition
switch to the “ON” position.
• Pull the front or rear brake lever.
• Press the starter button and allow the engine to crank for a few
seconds, and then measure the ignition coil primary peak voltage.
• Repeat the above procedure a few times and measure the
highest ignition coil primary peak voltage.
V Tester knob indication: Voltage ()
 Ignition coil primary peak voltage: More than 80 V
"
If the peak voltage is lower than the specified values, inspect the
ignition coil/plug cap. (10-21)
Before using the multi circuit tester and peak volt adaptor,
be sure to refer to the appropriate instruction manual.
While testing, do not touch the tester probes and
spark plugs to prevent receiving an electric shock.
