-===== DIY crankcase breather with Screamin Eagle AC  =====
-|Crankcase vented to atmosphere, while keeping the Screamin Eagle air cleaner. Parts include some 1/4 fuel hose, a 1/4" vacuum nipple, a 1/4" vacuum tee, and a 1/4" vacuum elbow. If you look at the base of the air cleaner there is a lug molded on the right side. I drilled a 7/16" hole through the lug, the 1/4" hose has to be forced through the 7/16" hole creating a tight seal. I ran the 1/4" hose to the bottom of the bike and zip tied it out of the way. The Screamin Eagle air cleaner uses the rubber elbows to direct the crankcase gases into the carb. I cut them in the straight section and connected the hoses there. The rubber pieces on the breather bolts are part of the Screamin Eagle air cleaner kit, part number 63520-04. Other parts can be bought at local auto parts stores. ((Pics by gravydog of the XLFORUM http://xlforum.net/forums/showthread.php?threadid=2039569))|||
