• Remove all of the spark plug caps and spark plugs.
• Connect four new spark plugs to each spark plug cap and
ground them to the crankcase.
NOTE:
Make sure that all of the spark plug caps and spark plugs are
connected properly and the battery is fully-charged.
Measure ignition coil primary peak voltage (for #1 and #4 cyl-
inders) in the following procedure.
• Connect the multi circuit tester with the peak voltage adaptor
as follows.

• Shift the transmission into neutral, turn the ignition switch to
the “ON” position and grasp the clutch lever.
• Press the starter button and allow the engine to crank for a few

age.
• Repeat the above procedure a few times and measure the high-
est ignition coil primary peak voltage.
