im not sure how much it takes so put a quart in and check your dip stick[ i asume it has one] and just keep adding as it needs it. if you have an oil filter on it i would change that to. when you have your oil to a good level run your quad for a little to get it through the filter, let it sit so the oil settles and check the dip stick and add as needed, thats what i did on my 300ex but im not sure on how different my engine is compared to yours, but if im wrong someone on here will let you know
