IGNITION COIL RESISTANCE
• Remove the fuel tank. (
• Disconnect the spark plug caps and coupler, and remove the
ignition coil.
Measure the ignition coil resistance in both the primary and sec-
ondary windings. If the resistance is not within the standard range,
replace the ignition coil with a new one.

Tester knob indication: Resistance (Ω)
Ignition coil resistance
: 2 – 4 Ω Ω Ω Ω Ω (+ + + + + tap – - - - - - tap)

CKP SENSOR PEAK VOLTAGE
• Remove the seat. (
• Remove the tray.
• Disconnect the ECM coupler.
NOTE:
Make sure that all of the couplers are connected properly and the
battery used is in fully-charged condition.
Measure the CKP sensor peak voltage in the following proce-
dures.
• Connect the multi circuit tester with peak volt adaptor as fol-
lows.
+ Probe: White lead wire
- Probe: Black/Brown lead wire
09900-25008: Multi circuit tester set
Before using the multi circuit tester and peak volt adap-
tor, be sure to refer to the appropriate instruction manual.
• Shift the transmission into the neutral, and then turn the igni-
tion switch to the "ON" position.
• Pull the clutch lever.
• Press the starter button and allow the engine to crank for a few
seconds, and then measure the CKP sensor peak voltage.
• Repeat the above procedure a few times and measure the high-
est peak voltage.
Tester knob indication: Voltage (
CKP sensor peak voltage: More than 2.7 V
If the peak voltage is lower than the specified values, check the
peak voltage at the CKP sensor lead wire coupler.
