IGNITION:
The ignition system is a CDI-system without any
contact-breaker to change or any other moving
parts apart from the flywheel. However, the system
has to be frequently checked and cleaned for a
maximum of durability and performance.
The inside of the ignition cover, the stator, the
flywheel and the surroundings are preferably
cleaned after every time the motorcycle has been
used and/or washed (cover removal; three allen
screws, allen key No.5). Due to the heat of the
engine a condensation is built up around the stator
and flywheel which could cause the system to
work improperly. Check the surface of the cover
for any damages in order to avoid any leakages.
Frequently check the spark plug (Fig. 7E-1) for
wear and the colour of the electrode coating (spark
plug wrench, article No. 270007-01). The colour
ought to be pale brown. A dark or black colour
means that the carburettor's setting is on the rich
side and a light or white colour means that it is
too lean (see "FUEL & COOLING -
CARBURETTOR”).
Check also the spark plug electrode gap. The
correct electrode gap is 0,6 mm.
Recommended spark plug is NGK DCPR8E.
Tightening torque 12 Nm.
Ignition timing:
Remove the inspection cover (Fig. 7F-1).
Put the engine in TDC position (see ”ENGINE -
VALVE ADJUSTMENT”).
The ignition is propely set if the right mark on the
flywheel (Fig. 7G/H-2) is aligned with the mark on
the stator (Fig. 7G-1).
If the ignition needs to be adjusted, remove the
cover, slightly undo the three screws of the stator
(Fig. 7H-1) and adjust the stator.
Tighten the screws.
