● Turn the ignition switch to the "
● Grasp the front or rear brake lever.
● Press the starter switch 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.
Ignition coil primary peak voltage
Tester knob indication : Voltage (
WARNING
While testing, do not touch the tester probes and
spark plug to prevent receiving an electric shock.
If the peak voltage is lower than the specified values,
inspect the ignition coil. (Refer to below)

● Lift and support the side cover with the side cover
stay. (Refer to page 2-2)
● Disconnect the ignition coil read wire.
Measure the ignition coil resistance in bolt the prima-
ry and secondary windings. If the resistance is not
within the standard range, replace the ignition coil
with a new one.

▣ ▣ PICK-UP COIL RESISTANCE INSPECTION
● Lift and support the side cover with the side cover
stay. (Refer to page 2-2)
● Disconnect the pick-up coil lead wire coupler.
Measure the resistance between the lead wires and
ground. If the resistance is not specified value, the
pick-up coil must be replaced.
