How to know if auto lube works

[Haideris]

Hi, I am new at this site.
So I always mixed oil in gasoline, and I decide maybe I can fill oil in tank.
So how to know if auto lube ir working ?

I guess you don't really. Which is why the engine fails and then they realise the oil pump failed.

Clear lines from the pump to the intake helps though, as the vacuum will suck the oil out, but the pump won't displace the oil back in there.

You could fill oil tank, bleed pump and run bike on premix with oil discharge pipe disconnected into a milk bottle amd see if it works with engine running, rotate pulley on oil pump to max for maximum discharge. Will give you an idea if its doing anything at all.
