While visiting a friend the other day, he wheeled out a nice old BSA Scrambler...think he said a 1969. Had not been run in some months/years. Fired up first kick. He was about to hop on and take it down the road when I noticed what looked like whipped up oil pouring out underside of engine. It was light, creamy brown, not a black/clear brown. Must of been 2-3 liters within a few seconds.
Well, he poked around a bit, but had to head off to pickup his daughter from school, leaving me to browse through the workshop manual.
I come to a paragraph regarding a common siphoning issue that occurs after storage...with two check valves on feed/return lines to be suspected.
When he returns, we set about to located and clean up said check valves and after replacing new oil, she starts up nicely, no more sewage from below. Feeling very pleased at the fix but still don't quite understand where this siphoned oil was spewing from exactly. I suggested it had filled the primary and came out the drive sprocket opening like has happened on my Norton recently, but primary oil level seemed good.
