It was a easy fix all I had too do is loosen two screws and remove the air filter cover to gain accesses too the old air cleaner filter and pre cleaner filter then remove them and replace them with the new ones, put the cover back on tighten the two screws and that\'s it. Although I did soak the pre cleaner filter in new motor oil then ri nged the excess oil out of it as suggested by the instructions that came with that part.
