So the old girl is being difficult again after a nice long stretch of awesomeness. She cranks but will not start.

-I have fresh oil, new fuel pump, new battery, new Fuel Filter, plugs about 1 year old...

The twist is there's a bit of oil under her:

Looks like it's coming from the boot of the clutch line where it enters under the bike:

Wish I knew what model and year you have. There are some differences.

Most of us put that information in the signature line at the bottom of the post. It's in your profile settings.

An oil leak wouldn't prevent the engine from starting (if all the oil leaked, it might help stop it running in a seriously bad way!).

First thought about the non starting - the obvious, did you reconnect the fuel pump plug (right hand side under rear of fuel tank? You won't be the first nor the last to forget this essential action! With it disconnected the starter will churn merrily away and the bike will never start - big clue is that you don't hear the fuel pump whine immediately after releasing the starter button.

If it was the side stand or other interlock, the engine shouldn't crank at all.

Oil leak - having looked at pics. Very likely that your clutch actuating arm boot has become cactus. I had this issue very recently. Not a hard job to do but worth considering replacing the actuating arm needle bearing while you're in there (PITA job to get the old bearings out though). Some hints and tips at the link below:

I did check the connection under the tank...it seems to be connecting and is definitely plugged up.

Mine has started with the side stand down as long as the clutch lever is pulled in since I had her(3 years)

I'm guessing you mean plugged in. Your bike had a problem with that plug last year. Be certain the pins and sockets are clean and that they are making a tight connection with each other.

Is power at fuse #6? Is the fuse ok? Are the grounds clean and tight? Is the battery fully charged?

Good memory! I did check ALL the fuses. The battery is charge up. The leans to the connector under the tank seem to be solid. I guess I could replace the plug if you guys recommend a better option to eliminate it from the culprit list.
