Assembling dust cover and lead

IGNITION SYSTEM
1. Loosen ignition coil bolts and insert 0.3 mm
(0.012 in) feeler gauges of two magneto wrenches
895115-00330 (A) respectively between both ends
of ignition coil core and flywheel magnets.
2. While holding ignition coil against the feeler
gauge between magnets of flywheel and ignition coil,
tighten bolts.
Standard gaps : 0.3-0.4mm
NOTE: If air gaps are too wide, this system will not
generate sufficient energy and give a weak spark
or an incorrect ignition timing. If the gaps are too
close, the ignition coil can interfere with the flywheel.
1. Set grommet into the notch of crankcase as
shown.
2. Insert flywheel side corner of dust cover (A) into
crankcase and then press in bottom side of the cover
while pushing the flywheel side corner to crankcase.
3. Make sure that grommet on high tension lead is
properly seated between crankcase wall and dust
cover (A).
4. Fasten dust cover (A) with a bolt.
5. Connect primary lead coupler and reinstall other
remaining parts in place.
