With Motul 5100 I think it is common to have a small amount of slipping when changing gears at high revs. I'm pretty sure I have read somewhere on here that this is quite a common occurance. I know mine does it when I'm really using the rev range... Not a huge amount though, but noticable.
Maybe someone can shed more light on this for both of us...?
