Angry Compression Questions

Updates with the even longer than anticipated project bike!

This thing is driving me nuts especially since the only time I get to work on it is during the holidays. Being a full time college student really blows.

Anyyywho, listen to this I got 60psi on one cylinder and got absolutely 0 on the other. Which was my fault of improperly setting the valve lash.

However, I am now using a compression leak down test kit in order to see where I am getting these issues of bad compression and ive narrowed it down to this. Basically I am getting 50% hold on compression which is really bad, but it is not leaking from the oil fill plug nor the intake or exhaust.

it leaks from the other spark plug well, and a small hole on the side of the Cylinder Head. See this is my thinking, if it can pass through the sparkplug well its probably a faulty Cylinder Head gasket. But I wanted to see if anyone had some input on this
