Sudco 016-167 Keihin Pwk38 Carburetor Quad Vent/air Striker
The oval shaped throttle valve concentrates air flow over the main fuel circuit to increase low end response. Yet, the narrow design allows minimum interruption in the venturi for maximum air flow. The new “air striker” flow channels and “quad vents” have been added to the PWK35 and PWK38 providing instant throttle response.
