you have to replace the valve and blueprint the valve seat, than maybe engine will run, but it's a punk way.
good way is a overall because your engine was assembled from garbage, I can say it that ducati engines based on big cranckase MY1999 wasn't have the oil cooled cylinders, it was just air cooled and oil cooler for motor oil.
Who did it we don'tknow and how they did we don't know too. So do you want to ride a dead dog?
