Hello. Does any one haves a manaul which contains the driving instruction for 1930-1933 models with hand lever shifter (not foot gear pedal) and the diagram of the things from the handbar?
Old motorcycles used total lost oil system. By 1930 how did this system worked?
If you're a club member then there is a handbook in the Members Area on the website for 1930-36 models which has hints about riding / hand gear changes, etc. ..... go to the members area and click on Library Search. Another good reason to join (if you haven't already!!).
Bit late, but oil was gravity fed to the Pilgrim pump which fed a continuous small amount of oil into the timing case, and then into the crankcase. The flywheels dipped into this oil and splash fed the big end and cylinder bore. Some of this oil was then blown out of the crankcase breather to lubricate the primary chain and ends up on the floor when you park the bike. Over time, the level of oil in the crankcase slowly builds up, and more oil is blown out of the breather. It is for this reason, and oil contamination, that BSA recommended draining the crankcase every few hundred miles after which a teaspoonful of oil should be poured into the cylinder to provide initial lubrication after draining. In other words, fresh oil enters the crankcase and is blown out of the breather.
Hence "Total loss".
It is important to turn the oil supply off when not in use, otherwise oil will drain into the crankcase, making starting very difficult.
