Motorcycle Carburetors with Velocity Stacks and Air Filters

This item comprises a set of two motorcycle carburetors, likely from a twin-cylinder engine, along with two aftermarket velocity stacks fitted with mesh air filters. The carburetors appear to be constructed primarily from aluminum or a similar light alloy, showing a metallic gray finish typical of cast components. They exhibit signs of age and use, including some oxidation and grime, indicating they are not new but rather used parts. The external linkages, springs, and brass-colored jet mechanisms are visible, suggesting a standard carburetor design for internal combustion engines. One carburetor's float bowl is visible on the right side. The overall construction appears robust, engineered for the demands of an engine environment. There are no immediately visible manufacturer's marks or part numbers, which would typically be stamped or cast into the body. The accompanying velocity stacks are also made of a machined metal, silver in color, and feature fine mesh screens at their inlets, designed to prevent larger debris from entering the engine while maximizing airflow. Their condition appears relatively good, though the mesh may show some discoloration from use. The rubber sealing rings at the base of the velocity stacks suggest a specific fitment method. The items display a utilitarian aesthetic common to mechanical engine components, without decorative elements. Given their appearance and likely materials, these components seem to be from a motorcycle spanning from the 1970s through the 1990s, an era when such carburetor setups were prevalent before widespread fuel injection.
