Secondaryairsystem - PIAGGIO X7 125 2012 Manual

Secondaryairsystem (03_12)

In order to reduce polluting emissions, the vehicle is furnished with a catalytic con-
verter in the muffler.
To facilitate the catalytic process, a further quantity of previously filtered air is brought
in through the exhaust duct on the head by the secondary air system (SAS).
This system allows more oxygen to be added to the unburned gases before reaching
the catalytic converter, thus improving the catalytic converter reaction.
The system has a control valve that disables operation during deceleration in order to
03_12 avoid abnormal noises.
To ensure the best functioning of the SAS, take your vehicle to an Authorised Piaggio
Service Centre for maintenance operations, at the intervals indicated in the scheduled
maintenance table.
This system requires a filter «A».
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.
