This modification can lower CO emissions at high altitude by:
1.
Enlarging the secondary air filter outlet diameter thereby allowing more air to reach the
catalytic converter.
2.
Enlarging the
carburetor's
altitude compensator port leaning out the
air/fuel mixture at altitudes above approximately 3900 ft.
