Ignition (Kokusan)
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.
Spark plug
– Set the electrode distance.
Electrode distance: 0.60 mm (0.024 in)
Insulator
Check for cracks and fissures.
!
CAUTION
!
A
LWAYS USE A SPARK PLUG WITH RESISTOR. OTHERWISE PROBLEMS CAN OCCUR IN
THE
CDI UNIT.
Check stator and pulse generator (Kokusan)
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.
