Hello boys and girls! I have a CT that runs like a honey, as long as you can outrun the smokescreen. The valves seem to be seating well, rings look good (still springy), cylinder looks undamaged. What I did notice when I took off the head and jug is that there seems to be a lot of oil coming from the upper right stud. I know that oil divider feeds the intake valve, so I should see a little oil. I'm wondering if the gasket is bad or a blockage preventing the oil from draining... then finding its way to the cylinder? My harbor freight leak down tester shows in the green, with some leaking out the intake and rings, but definitely serviceable. I don't know what else could be. I'm going to try and google it, but if someone could share the route the oil takes in the head, that would be useful. I noticed the aluminum cam chain cover was hot when running. I do have oil flow, I checked that. For what it's worth, things got worse after an oil change.
