I think this was the exact problem the original K1200S bikes in Europe suffered as mentioned above.
A lot of times, parts like this are contracted out to different companies. Like pistons, conrod and crankshafts.
Not everything is made in house at BMW.
So the QC has to be up to snuff at the camshaft factory as well.
Also they are at the mercy of their metal supplier to ship quality metal to them. Sometimes a bad batch gets through and unless every batch is checked, sometimes a set of cams will be poor.
No excuse, just saying...
'06 K1200R- in pieces
'73 Honda CB500F- slow but fun.
'77 Yamaha XS 750 triple- kinda
