Remove the inspection cover, see p. 56 (REMOV-
ING THE INSPECTION COVER).
Connect an electronic revolution counter to the
spark plug cable.
Start the engine.
The minimum speed of the engine (idling) must be
about 1800 100 rpm; in this case the engine does
not make the rear wheel rotate.
If necessary:
Act on the adjusting screw (1) positioned on the
carburettor.
By SCREWING IT (clockwise), you increase the en-
gine rpm.
By UNSCREWING IT (anticlockwise), you decrease
the engine rpm.
Twist the throttle grip, accelerating and decelerat-
ing a few times to make sure that it functions cor-
rectly and to check if the idling speed is constant.
c
Close the inspection cover.
Do not act on the air adjusting screw, to
avoid variations of the carburation set-
ting.

If necessary, contact your
