I was gonna ride to my girlfriends house and checked the oil and it was below the mark so the site glass is really starting to fuck with my mind as MJH said. Got my cheap measuring cups ready to go so Im gonna drain it and measure it. If the manual says 850ml then thats what Im gonna put in it. Im putting 10w40 cycle oil in it. Whats the diff btwn cycle and motor oil btw?
