Ignition (Kokusan 4K2)

General information
The measurements described below will only reveal severe
problems. Coil short circuits leading to weak ignition sparks
or low generator output, respectively, can only be detected
with the help of an ignition test bench. In the case of
malfunction always check the cables and the plug and socket
connections of the ignition system first.
Make sure to select the correct measuring range when
performing measurements.

Checking the stator and the pulse generator (Kokusan 4K2)

Use an ohmmeter to perform the following measurements:
NOTE: The measuring must be performed at a temperature of 20° C.
Otherwise significant deviations must be expected.
MEASUREMENT
red/black – black/red
Stator
Pulse generator
Replace the stator and/or the pulse generator if the measured values
deviate significantly from the setpoint values or in the case of continuity
between one of the cables and ground.

Replacing the stator (Kokusan 4K2)

– Loosen the 3 bolts and remove the stator.
– Insert a new stator into the ignition cover.
– Apply Loctite 243 to 3 new bolts and tighten the bolts.
– Insert the cable guide in the opening provided for that purpose in
the ignition cover.
