I ran amsoil in my 1k and was told not to. The guy at the dyno shop told me because the oil was so slick and my bikes clutch being lubercated by my oil it would make the clutch slip faster. He stated he saw a hp loss on the dyno. Now I never noticed anything on MY bike but that's what I was told. That's just my opinion and I'm sure some of the guys on here will have theirs, so for what it worth I would look into it. Again not trying to say good or bad about amsoil I use it in cars, trucks, and bike. Good luck
