New Beemer DOHC Valve Arrangement

The 2010 RS1200GS (and RT's) have the new DOHC heads. I was curious about how the valves would be adjusted so I found this picture and set of instructions


The cam followers slide out after removing the E-ring retaining clips.  Adjustment is made via different size semi-spherical shims.  A bit of a pain to stock a supply of shims, but overall it seems to be much better (i.e. easier to adjust) than typical shim-under-bucket arrangements.
