Hi Mark,
I have and love your service manual for the XR and by far my biggest challenge to date is figuring out the darn BMW electrical connectors and how to disconnect them. I'm currently doing the fork oil and trying to release the ESA cable from the frame attachment so I can remove the fork, having already released the cable from the male bottom part. Nowhere do I see any guidance on how to access and release the cable from the frame. But this is typical of my challenges with these connections and I'm wondering if there is any sort of chart or something that shows the types of electrical connections used and how to release them? I seriously spend countless minutes trying to figure the darn things out.
And I've been wrenching on bikes for many years, and am no stranger to electrical connections generally. These seem more mysterious to me for some reason.
