INSPECTION

IGNITION COIL PRIMARY PEAK VOLTAGE
• Remove the fuel tank. (6-3)
• Remove the frame head covers. (3-3)
• Disconnect the spark plug caps.
• Connect new spark plugs to each spark plug cap and ground
them to the cylinder head.
NOTE:
Make sure that all couplers and spark plugs are connected prop-
erly and the battery used is in fully-charged condition.
Measure the ignition coils primary peak voltage in the following
procedure.
• Connect the multi-circuit tester with peak voltage adaptor as
follows.
+ Probe: White terminal
#1 ignition coil:
- Probe: Ground
+ Probe: Black/Yellow terminal
# 2 ignition coil:
- Probe: Ground
NOTE:
Do not disconnect the ignition coil primary wire coupler.


Before using the multi-circuit tester and peak volt
adaptor, be sure to refer to the appropriate instruction
manual.
• Shift the transmission into neutral and turn ignition switch
"ON".
• Pull the clutch lever.
• Crank the engine a few seconds with the starter motor by
depressing starter button and check the ignition coil primary
peak voltage.
• Repeat the above procedure a few times and measure the
highest ignition coil primary peak voltage. If the peak voltage
is lower than the specified values, inspect the ignition coil.
 Ignition coil primary peak voltage: 205 V and more
Tester knob indication: Voltage ()

Avoid touching the tester probes and spark plugs to
prevent an electric shock while testing.
