Oily Spark plugs
OK, so I took out my spark plugs and i noticed that theres black fluid on them, either burnt fuel or oil. Should i take off the cylinder head and check it out, or just clean off the spark plugs. I am already in the middle of replacing the shims because there was 0 clearance on all eight of my valves. Any help would be great.

No, don't take it apart just yet. Finish up the valve adjustment, synch the carbs, new plugs, get the ignition working right, do all of the other routine stuff that hasn't been done in forever, and then ride it a while. Check the compression, ride it more and then decide if it needs work.
Black and shiny is usually oil, but there can be other reasons besides a shot engine. Black and dry is fuel.
Does the engine run now?
How is the compression?
What engine are you talking about?

I had oily plugs and it turned out to be a head gasket problem.
Usually the plugs will look shiny very glossy.
