Kawasaki Clean Air System
The Kawasaki Clean Air System
(KCA) is a secondary air suction sys-
tem that helps the exhaust gases to
burn more completely. When the spent
fuel charge is released into the ex-
haust system, it is still hot enough to
burn. The KCA System allows extra
air into the exhaust system so that the
spent fuel charge can continue to burn.
This continued burning action tends to
burn up a great deal of the normally
unburned gases, as well as chang-
ing a significant portion of the carbon
monoxide into carbon dioxide.
Air Suction Valve -
The air suction valve is essentially a
check valve which allows fresh air to
flow only from the air cleaner into the
exhaust port. Any air that has passed
the air suction valve is prevented from
returning. Inspect the air suction valve
in accordance with the Periodic Main-
tenance Chart. Also, inspect the air
suction valve whenever stable idling
cannot be obtained, engine power is
greatly reduced, or there are abnormal
engine noises.
Air suction valve removal and inspec-
tion should be done by an authorized
Kawasaki dealer.
