+====== 86-90 Engine Breather Mod Using #4 Cam as an Oil Slinger ======
+This is an idea based from the breathing on the BMW Rotax twins. \\
+They have holes on the outer edge of the gear for the water-pump and the gear sits on the end of the inlet-cam. \\
+CC pressure exits the center of the cam without any oil in the air-box. \\
+The idea is to let the engine breathe thru one of the cams, thereby use the rotation to fling the oil out of the air. \\
+(preventing oil mist coming out when going fast over an extended period) \\
+This set-up is just to separate the oil from the air (thru the cam). \\
+Air comes into the cam thru an opening as far from the center of the cam as possible to let centrifugal force fling the oil out of the air. \\
+Then, the air exits the engine thru the center of the cam via an extension through the cam-cover. \\
+The cam is to have a fixed tube straight through the cam-cover and into the cam. \\
+And then a seal on the end of the cam where the tube goes in the cam cover. \\
+From there the air is fed through a reed or umbrella valve to atmosphere. \\
