i bet its the seal behind the front sprocket .It will fool you .What you need to do is take sprocket cover off clean around Tthe shaft seal real good ,ride the bike get it good and hot.put bike on side stand let it idle and watch shaft seal.Cut it off and watch for oil allso.What hapens about 80% of the time the oil runs out of seal then runs down the shifter cover and you cant see that the seal is leaking.I found this out the hard way lol.
