The purpose of drilling an air box in a Yamaha V-Star 1300 motorcycle is to draw more air into the engine to mix with the gas. Newer models use cone filters. Older models use a top-mount square filter that rests on the inner edge of the air box. Air boxes that use cone filters can be drilled all over the box and top-mount filter boxes can only be drilled on the top cover. Anyone who owns a V-Star can drill the air box with a few basic tools.

Remove the mounting bolts from the right and left side of the seat with a box wrench. Pull the seat off the frame of the V-Star and set it aside.
Lift up on the two fasteners on the right and left sides of the air box and remove the top. Remove the filter from the air box. If the filter is a top-mount, pull it out of the air box. If the filter is a cone, unscrew it and pull it from the box.
Drill small holes into the top of the box using a power drill and small drill bit. If the filter is a cone, drill holes on the side of the box and top. The pattern of the holes doesn't matter and about 30 to 50 holes should do.
