Oil Leak

So I'm in the process of fixing up the bike I just bought. It's an 83 VT750. Of course, when I got it home, I tried to start it up right away, and managed to get it running for a little while, but it would'n't idle and I figured the carbs were going to need cleaning anyways. So I took the carbs off and took them down to my father (mechanic). He's basically done with them, just waiting on a new vacuum piston that I've ordered. It should be here tomorrow.

Anyways, for the short while that I did have it running, it must have been long enough to get things warmed up and fluids flowing and what not. Now I have an oil spot on the floor below my bike. Its not much oil, a spot about the diameter of a beer bottle ring... ironic, I know. But then again I didn't have it running long either.

I believe the leak is coming from the bottom left side of the motor, although I can't be sure. The bikes center stand has been removed by a previous owner, so it always leans left on the kick stand. I suppose it could be running down the bottom of the motor and dripping off the the left side. But I'm almost certain it's coming from the left. I'm also certain that its oil, and not coolant, as it hasn't evaporated after a few weeks and is still very wet and slippery. Color is hard to tell has my floor is dirty concrete.

I tried to crawl down there an take a look, but its hard to see real clearly that low. The outside of the oil filter is pretty messy. Looks like oil on it.

Anyways, my question is... are there any notoriously problematic spots that I need to check out to find this leak? Is there some sort of seal or gasket that I can replace myself, or do I need to take her to the shop? Tell me, please, that I don't have to take the motor out!

Sorry I wrote a book and thanks for reading this far. I just want to be a descriptive as possible.

IIRC the oil drain plug is on the left side. It may be as simple as that.

The drain plug would REALLY be nice.
Most issues with these motors based on oil leaks, require the engine OUT to fix!

At least around here, local dealers wont touch a bike this old...

Cam plugs will leak, and can BARELY be changed with engine in (honestly thinkin, I don't really know if even that is possible). I just got one of these bikes...it leaked all over...including jug to block gasket.

I really hope its as simple as that! Guess I'll find out this weekend when I change the fluid, reinstall that carbs, and hopeful get her running.
