Here is my story, I bought a 400 ex in serious need of attention, I have now replaced the piston and rings, replaced the head with a used head, and replace the valve cover with a good used one, The problem i now have is this. The machine starts and runs like a champ, I am just not getting any oil on the cam chain side of the top end, it is causing a tap noise. I have since pulled the side cover and cleaned out any miscelaneous junk and gunk, still i am not getting oils to the top. I am preparing to change the plunger and spring under the cam now, does anyone know what would cause this? Any ideas on where I should be looking next?
thanks
