Iíd start by checking the plugs again. After getting the oil level corrected you shouldnít have black plugs anymore, unless itís an issue with the tune you have in the ecu. Are you sure you donít have too much injection cleaner in the tank ? Did it start running worse after buying fuel ? If the plugs look ok, take it out and ride it hard, see if it gets any better. Run that fuel as low as you dare and put some fresh in from a different source. You could have water in the fuel.
