I was wondering how much oil and 5w 30 or what to put in my yfz I got it on trade and have no idea. and is there a site glass or a plug to pull, on the cases to find the correct oil level. like on my crf250r you pull a plug and when you get oil coming out you are done cap it off and that's it. also what does the reservoir hold and is it for the clutches, cases?
