Suzuki Shogun FL125 oil filter has a different design with Smash or Shogun 125 long. Not only smaller, but the outsides have the same shape with the inside of the hole (fig. 1).
Unlike the old design on the outside of the Smash and Shogun 125 long, meeting forms (fig. 2). When pressed in, a by pass filter is dirty and bumpet. Another advantage, mechanical or bikers are guaranteed not to be reversed pairs. Because, if not reversed will be closed.
Let no one go, pay attention to each shape, the new included. The part that should be inside or go in first, sure the hole is not clogged. Invisible visible. If you want the easiest way, pay attention to both sides. See the existing layer of black rubber. That part should go in first. Being part no rubber, it is for the outside. (fig. 3).
