Oil leak from cylinder base?

[eman13261]

Hey guys so after a ride I looked down and what do I see, a nice healthy line of oil leaking from my engine. Seems to be a cylinder base gasket? I have a decent amount of experience with these bikes but haven't gone that deep into an engine. Any opinions on other things I should be looking at, other gaskets/seals and bolts? I know there are other threads and I've looked at them but I find it helpful to get some answers specifically for my scenario.
Thanks

Update: looks like its following a trail down to the base but I'm not quite sure I have to wipe it clean and go from there...Very distracting when I'm taking summer college courses.

I would torque the head and see if the leak stops. Brass or copper washers on the 4 outer studs. I would get a gasket set. New cam chain is a good idea. Front guide is usually shot due to age.

The head gasket is leaking. Torque the head is all you can do other than a teardown.

Could be a simple camshaft oil seal,look under the points cover and see if there is any oil in there.

I'll open them up when I get home but if doesn't look like that's the source of the oil. Hopefully it is that's an easy fix

Do I see a crack there? Beneath that bulge is the left case main oil gallery...

It was just dirt that looked like a crack. I took a wrench to the bike and I think I found the source. Camshaft gasket under the points cover has some oil leaking from it and there was a nice oil ring around the cover. Still planning on retorquing the head bolts with brass washers just to be sure
