Yamaha - Oil Injection Pump Assembly Oil System Pump 6D0-13200-04-00. Overview. On Yamaha two-stroke setups, the oil injection pump is one of those parts you never want to second guess. It's responsible for feeding the engine the right amount of oil at the right time, and when it's off, you'll feel it quick. I've seen motors run rough or worse when the pump starts failing. When it's working right, though, everything stays smooth, protected, and running the way it should..
