ABSTRACT:
A lubrication system for the internal combustion engine of a motorcycle that includes a pump that outputs a constant amount of fluid per cycle of operation and a delivery valve which selectively passes lubricant to the engine or returns lubricant back to the system to vary the amount of lubricant supplied by the lubricant pump. The system is designed so as to self purge air from the system by mounting the lubricant pump and the delivery valve in close proximity to each other and at a lower level than the lubricant storage tank. In addition, the engine is supplied with arrangement to preclude lubricant from draining into the engine through the delivery valve when the engine is not running.
