Still no spark?
Check other cables and connections
for poor contacts (dirt, corrosion, cable
breakage and damaged insulation).
Make sure that the cables are correctly
drawn and lie in the cable grooves.
Do not forget to check the cables in the
throttle too.
See chapter 3 "Throttle".
TIP!
Use an Ohmmeter in order to easily
check if cable breakage has occurred,
due to pinching, for example.
Still no spark?
Check the air gap between the fl ywheel
magnet and the ignition module. The
gap should be 0.3 mm.
Use a 502 51 34-02 feeler gauge.
See "Dismantling" below.
Adjust the air gap as needed to the cor-
rect value.
• Loosen the bolts.
• Position the feeler gauge and press
the ignition module against the fl y-
wheel.
• Tighten the bolts and check the air
gap again.
If the spark plug still does not fi re, the
ignition system should be replaced.
