I was wondering if someone could help me figure out how the oil pump works on these bikes. I know it has a bleed hole on top of cylinder which you unscrew and while bike running, the oil should come out of their as a sign that oil is flowing to the cylinders nicely.

Right now, i tried adjust the oil pump gear but just cant figure out how to get oil to come up their.. It was working fine until i took the whole engine apart and cleaned the whole engine.. I bike fires right up and i thought i aligned everything that needed to be aliged according to the book. As for aligning the oil pump with the camshaft i just dont understand it... I can post pic if you want.... but anywho,Now my oil pump doesn't work please help if you can, thanks ahead of time.
