Panheads are for cruisin' . . . Sportsters are for racing !
The Rear Chain Oiler can be shut off by bottoming out the screw. You may also want to attach a short hose and plug the end, just in case of leakage. Plug the Primary Oil Return. The Crankcase Vent is where you plug in your fancy $75 Krank Vent (one-way valve). Make certain you install the Krank Vent on the proper direction (as per our conversation).
NOTE: You can see on photos 2 and 3 the shorter rod should only fit into the movable side. It was touching the stationary(notched) portion of the bearing previously.
