Im in the process of rebuilding my bike and engine after a winter stripdown and came to put the oil pump in and figured i would bleed it manually before bolting it in. I have never disconnected oil lines to the pump or disconnected it electrically, oil comes out of the bleeding point bolt and also if i pull the splined shaft out of the pump body but it will not come out of the nipples (lines to carbs are attached to carbs still i just wanted to make sure it was coming out of pump first) when i turn the shaft. I have tried with ignition on and pulling oil pump cable as well. Can anyone give me any tips? I take it that the ignition does have to be on? The only other thing is that i dont have carbs on yet, and im not getting any noise when i turn ignition on like RC valves rotating but i take it that this is because carbs arnt connected.

Any help greatly appreciated,

Andy
