SECONDARY AIR
The working principie of the SAS for Leader 125 ce engines is
entirely similar to the SAS employed on 2-stroke engines.
The main differences are the following:
Secondary air enters directly into the exhaust duct on the
cylinder head, instead of entering through the exhaust pipe
as in two-stroke engines.
The reed valve found on 2-stroke engines is here replaced by
a membrane. The unit, indicated by an arrow in the figure, is
provided with a cut-off connected to the vacuum inlet on the
intake manifold to shut air intake during deceleraron, so to
prevent detonations in the silencer.
Air is sucked in through hole «A» and flowing through the
first filter is directed towards hole «B».
