-In the pics below, Buell rocker boxes were installed on a 1200R with XB heads using the Buell style rocker box PCV valves.
+Some have reported better engine breathing and less oil leaking out the breather valve by using these Buell rocker boxes. \\
-The OEM breathers were removed. \\
+(along with their corresponding breather valves (17607-00Y). \\
-The rocker mounted PCVs replace the OEM breather / umbrella valves. \\
+-2003 Sportsters will get rid of the middle spacer, eliminating one more gasket that could leak. \\
-The vent lines off the PCVs were tied together, ran thru a catch can and to the rear of the bike. \\
-|Both PCV valves are connected to a ‘Y’ connector that runs along the frame under the tank. ((photos by mick42 of the XLFORUM http://xlforum.net/forums/showthread.php?p=5762210#post5762210)) The tube \\ comes down into a catch can that can be emptied when it gets too much oil in it. On a long hard ride the \\ catch can will clean its self out.  ||
