Oil pump function on RZ350 

Third in the series, this focuses on the AutoLube oil pump function. Yamaha's AutoLube technique was developed in the early '60's. It is very important that it work correctly to properly provide oil into the fuel system on their 2-stroke engines. Without oil, you will seize the pistons or the crankshaft bearings. This video shows the pump functioning on my 1985 RZ350 Yamaha. I rebuilt the pump during the engine rebuild I performed in 2021.
