Typically, an air cleaner for a motorcycle is located below the seat behind the engine. However, when supplying air from the air cleaner placed below the seat to multiple carburetors installed laterally in parallel, such as in a parallel multi-cylinder engine, the air is supplied to the carburetors placed on both sides. The path becomes long and it becomes difficult to smoothly supply the same amount of air to each vaporizer. As a result, the output of each cylinder is different, and there is a problem that a sufficient increase in output cannot be expected.
