SECONDARY AIR SUPPLY SYSTEM
• This model is equipped built-in secondary air
supply system. The pulse secondary air supply
system is located on the cylinder head cover.
• The secondary air supply system introduces fil-
tered air into exhaust gases in the exhaust port.
The secondary air is drawn into the exhaust port
whenever there is negative pressure pulse in the
exhaust system. This charged secondary air pro-
motes burning of the unburned exhaust gases
and changes a considerable amount of hydrocar-
bons and carbon monoxide into relatively harm-
less carbon dioxide and water.
Remove the air cleaner housing (page 5-60).
