DJT, maybe your bike has a self defense mechanism after all... seeing how badly the pipes have been rusting she decided to bleed some oil in an attempt to healing herself...
Seriously, try the crankcase covers. It could be just a question of the sealing going away.
Copper washers not changed on an oil change also could be the reason indeed.
I hope Magny was OK.
Cheers
