Hello.
The engine has to be taken apart for changing the seals.
When you did that, I would suggest to also change the bearings.They might be rusty due to the long storage....

And the oil draining can be caused by the damaged oil seald. The pressure from the crankcase can be pressed through the damaged seals into the left side of the engine (where the clutch is located (producing an over-pressure there).
This overpressure causes the the oil to drop out of the engine....

In the end, it doesn´t matter where the oil comes from, because , as you said, the engine has to be regenerated .

Sorry for the delay and many thanks for all responses! I took the head off and cleaned everything up....not much carbon after only 1000 miles. Didn't notice any blow-by from the head gasket...cleaned everything up and used the spray copper gasket sealant to ensure a good seal. No love trying to start it....back fired a few times and refused to start. The bike will be a static display for a while until I want to delve into it more.

Yes...jug / barrel came off....rings inspected...no issues. I believe you are correct....crankshaft seal failure as a cause!

Well, maybe count yourself lucky. Replacing seals (+ main bearings?!) is cheap, compared to a ruined cylinder, which could very well have the same symptoms.

Commiserations. Any idea of the cause?

Puffs....collect new seals and come to the U.S. to assist in getting this bike running again......

I'm sure he would (I would too) if you paid the air fare...
