    760- rate of oil from oil injection pump

    Hi, While running premix in the tank, have been running the 2 oil injection lines to the carbs into a clear water bottle to observe the flow rate. Each line drips one drop every 1 1/2 to 2 seconds. Both lines very steady and constant. Is this normal? Thanks.

    Depending on your drill rpm, yes.

    yes that is pretty much normal at idle speed, the pump doesn't do much at that speed because Yamaha uses check valve in the oil lines, once enough pressure is built up it can go through the check valves.
