Have a 2001 XL 1200c picked up a few years ago, first year runs and starts without issue since then oil has been coming from cylinder breathers that dump into the air breather, after riding it saturates the air filter to the point the oil will start to cover the oil tank, after parking from riding it will start dripping from air filter onto exhaust, oil tank has not been over filled and oil gets changed every year, appears to be coming from both cylinders.
