You dont take "engine" oil
Your transmission takes oil, which can be motor oil, but you can get a better grade. I recommend Bel-Ray gear saver that is designed for this.
I believe yours will take 680 ml's. There is a plug on the clutch cover that the oil will run out of when you fill it. Measure it and fill it untill it runs out. That's what it will take. (Bike straight up and level)

Stator unbolts, do you mean flywheel? You need a puller for it, it threads into the flywheel, after you remove the center bolt, left handed threads.
