Installing a new stator (Kokusan 4K-3)
– Remove the 2 bolts 1 and take the cover plate 2 out of the ignition
cover.
– Remove the 2 bolts
3 of the pulse generator and the 2 bolts 4 of
the stator.
– Undo bolt
5 and take the retaining platelet out of the ignition
cover. Take the stator and the pulse generator out of the ignition
cover.
NOTE: When reassembling the unit, degrease and apply Loctite 243 to
the threads of all bolts.
– Put the new stator into the ignition cover and fix it with the two
bolts
4.
– Position the pulse generator in the ignition cover and fix it with the
two bolts
3.
– Put the cable guide into the recess provided for this purpose and fix
the cover plate
2 with the two bolts 1.
– Position the wiring harness, taking care to avoid tension, and use the

Ignition (Kokusan 4K-3)
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 (Kokusan 4K-3)
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.
Replace the stator if the measured values deviate significantly
from the setpoint values.
