Carburettor Setting - PIAGGIO Vespa LX 150 4T Euro 3 Service Station Manual

Characteristics
This system allows more oxygen to be added to
the unburned gases before they reach the con-
verter, thus improving the action of the catalytic
converter.
The air enters the exhaust duct from the head, and
is purified by a black filter.
The system is fitted with a control valve that disa-
bles operation while decelerating to avoid unwan-
ted noise.
To ensure the best functioning of the SAS system
clean the filter as indicated in the scheduled main-
tenance table.
The filter sponge should be cleaned with water and
mild soap, then it should be dried with a cloth and
slight blows of compressed air.
