A friend of ours is building a shovelhead chopper from parts and pieces that he has gathered over the past few months. Swap meets, friends, and word of mouth leads have brought most of the parts needed for the chop into a small one-car garage. A big twin swingarm frame with a weld-on hardtail section forms the basis for the new bike. A 1978 shovelhead engine was found, hauled home, and mounted into the completed frame. From this point on, the rest of the components were added until a running mock-up rolled out of the garage and into the sunshine. The engine was supposed to be “fresh,” but once fired up, the resultant top-end noise and the growing puddle of motor oil told a different story. The oil leak was from the open port in the engine cases for the primary oil feed. A simple pipe plug fixed the oil leak and the noise originating in the top end (i.e. the rocker boxes). The rest of the engine sounded OK, but we decided to check it out once the mock-up was completed.
