Valve Adjusting Plates a.k.a. "shims"

[Grumpy Goat]

In the picture below, the "adjusting plates" or "shims" are Item #7.



AS Cycles (a BMW dealership) apparently sells these in quantities of 8 for $8.20, for each given thickness.

My question is this - is there a set of shims I can buy of assorted thicknesses that will fit our engine? Chances are if i need to change any shims, I will NOT need one size.

Bike Bandit (nice reputable name!) claims to sell BMW R1200 shims here, but each and every kit says "Universal fit" and there is a BS note at the top that states "... are universal/custom fit components, and are not a direct fitment for your machine." That alone gives me pause when dealing with these people.

As we all know our boxers are from a different "universe" so these likely won't work ... or would they? Anyone with direct experience?
