I just change oil in my 525 for the first time and switched it over to Amsoil 20W-50. as soon as i fire it up, the oil gets full of tiny air bubbles. It looks like there is water in the oil, but there isn't. the filters are KTM and are in correctly. I think both screens are in correctly. I put the narrow end of the one screen in first. Is that how it goes? I've used this oil in other quads before and never had this problem so something else must be wrong.
