Abstract
An air cleaner housing includes an upper case, a partition wall and a lower case. The inside thereof is partitioned into an upper, filtered side and a lower unfiltered side. Intake funnel pipes, connected to front and rear cylinders, project into the filtered side. An air cleaner element is provided on the front side relative to a hollow plenum above the intake funnel pipes. Inlets in side surfaces of the unfiltered side face toward a V bank of the engine. During use, air enters the bottom of the housing, and is cleaned by the air cleaner element. The clean air flows through the filtered side of the housing, into the intake funnel pipes and toward the cylinders on the lower side. A raised portion is formed on the front upper side of the upper case, and the air cleaner element is disposed inside the raised portion.
