Major Oil Leak, Help needed

My bike is an 83 XJ-750 k, it had sat for around a year before I bought it. After I had cleaned the carbs and rode the kinks out of it, I noticed a small pool of oil on the top of the Crankcase below what I believe is the stator and the left side of the engine. It was originally a small leak, and gradually corrected itself over time and miles.

Today I started My bike and let it warm up before I took off, and there was a HUGE puddle of oil there, and no more oil left in the sight glass. It drips oil on the floor below it.

The general concensus is that it may be coming from the crankcase gasket, however I one time noticed oil dripping from the bottom screw of the stator/generator. No one is 100% sure where it is coming from

Have any you had this problem, if so how did you fix it. If not, do you have any suggestians?
