I recently developed a leak on the shifter side of the bike. I just changed the cam cover o-ring, the valve cover o-ring and they are not leaking. The oil appears to be coming out of the long head bolt near the front of the engine. It looks like it is seeping out the top. The oil is going down covering the front left corner of the engine and the starter. I put all new gaskets at 42,000 miles, including a new head gasket. I am leaning towards a possible loosen and retorque the head as a fix. Any other ideas about a hidden o-ring or anything?
