I haven't seen that part in the BMW K75/100 2V workshop manual here because it's dated 1988, pre-revision. It isn't in Haynes because Haynes is dated '88, also. I have seen it illustrated in the K1004V manual here, K1100LT/RT manual here, and I've seen it in my moto. It was a revision to late K75 models. Clymer omitted including the change in the Late Model Supplement of their Brick manual.
