Installing the Breather (Air Cleaner)

At this point, you have two, practical choices:

  • Modify your existing breather to accommodate the Genesis intake throat.
  • Purchase an S&S Super-G compatible style breather. There are dozens, if not hundreds, to choose from.

I chose to modify mine. I like the shape and look of it, plus I saw nothing I liked better. I also thought it offered good air flow... Not to mention that it was one less expense.

Modifying my breather involved modifying its backing plate. I have read that others have been able to simply cut a 2.2" (2 1/5", or 56mm) hole, centered around the existing mounting flange. Then they just drilled three holes for the mounting screws.

I decided to cut out a big square hole around my backing plate's mounting flange. That allowed me to make a replacement square from sheet metal, epoxy and rivet it in, then cut my hole in a slightly altered position. I wanted to reposition the breather slightly lower, and a little better centered from its original position. See photos below.

Tip: I made a template for the cut outs, shown below. If you wish to use the template, copy it to your computer, then print it using the sizing option in your print option control panel. Adjust the sizing up or down until the printed size of the template's scale-ruler matches your ruler.
