Good find! It sounds similar to the early days of a 'valve job'.

With that said, and being that it is such an easy adjustment, BMW didnt think of this in the first place. It is, after all, an adjustable setting. I would think that the best way to adjust it would be to take the exhaust off and use some sort of feeler gauge while making the adjustment.
