ABSTRACT:
A motorcycle having a secondary air supply for delivering air to the exhaust ports of the engine for assisting in exhaust treatment of the exhaust gases. Air is supplied through reed-type check valves which are positioned in a concealed portion of the motorcycle body for silencing noise. The conduit which connects the check valves to the exhaust ports extends vertically downwardly substantially throughout its length so that condensed liquids in the conduit will pass back to the exhaust port rather than accumulate in the conduit.
