INSPECTION
• Remove the seat and fuel tank. (5-3)
• Remove the spark plug.
• Disconnect the magneto lead wire coupler 1.
Measure the ignition system peak voltage in the following proce-
dure:
• Connect the multi circuit tester with peak volt adaptor as fol-
lows. (See table below.)
• Measure the highest peak voltage by depressing the kick
starter lever several times forcefully.
