 When air is allowed to be drawn back into the engine, it creates a mass that must be compressed by the pistons on downstroke as it is being vented out. \\
 This robs some power and will cause the engine to work harder (creating more internal heat at higher RPM). ((Deimus of the XLFORUM http://xlforum.net/forums/showthread.php?t=67658&page=18)) \\

+This was made by norseXL of the XLFORUM and is a direct derivative of the 86-90 breather valve setup.((http://xlforum.net/forums/showthread.php?p=5809352#post5809352)) \\
+A male threaded cap was made to screw into the female threaded body of the breather valve container as shown below. \\
+The center of the cap was drilled and tapped for a hollow (5.5mm) M10 bolt. \\
+The cam cover was also drilled and tapped for M10 threads. \\
+The brass adapter for the banjo also has M10 internal threads. \\
+The umbrella inside the body is the stock 91-03 umbrella. \\
+A 1.5mm hole was drilled into the bottom side of the body to drain any oil that makes it past the umbrella. \\
