Abstract
Abstract An air funnel assembly extending between an air inlet assembly and one or more carburetors on a two-wheeled vehicle. The air funnel assembly includes an elastic air funnel and an air funnel cover. The funnel and funnel cover are affixed to the carburetor or carburetors and extend in spaced relation towards the air inlet assembly. The components may be fixed to the carburetors by means of one or more clamp rings, may be additionally joined together by projections from the elastic funnel which are retained in holes in the rigid cover. A radially interlocking arrangement may be employed at the inlet from the air inlet assembly to retain the funnel thereto.
