To adjust the belt do the following:
Loosen the safety bolt located high up behind the reduction mounting
plate and the side bolt.
Once these are loosened then you can turn the cam with a n.27 mm
size wrench - careful to observe the 1 mm increments.
Once you have finished turning the cam remember to re-tighten the
safety bolts, first the exagonal bolt, by keeping firm the cam with the
wrench, and then the side bolt.
Should you notice any black rubber dust inside small pulley ( pinion),
your belt needs to be re-tensioned because it is loosing.
IGNITION (ONLY FOR ENGINE WITH HAND START)
In case the coil and/or the handwheel must be changed, it is compulsory to
turn to your dealer or to trained personnel, even if this operation can appear
simple at the first sight, since the timing of the engine, if wrong, can change
the performance and cause damage to the engine.
To check the timing: the distance between the coil and the flywheel magnet is
0,40 mm.
