    I have not heard back yet from my dealer, I did get a response from a senior tech at another dealership who is a friend of a friend. His take as relayed to me is:

    "He would rather see a cleaner, less scared cam, but when you take in that you have not had to adjust the valves in 35,000 miles, they are still in spec, your plugs are perfect, bike runs good and no unusual noises, he goes with the theory that if it ain't broke, don't fix it. We talked about the soft cam issues of the past, but your bike was produced well after those issues. He did say that you now have a base line to reference in these pics. Save them and to pull the valve covers in your next maintenance and compare what you see then to what you have in these pics. If there is significant degradation of the surface, you might want to sit with your service manager and see what good will he might be able to give you. Cam surfaces are not a wear item. But he doubts that you will have to do that...………...

    Those look like the hardening is about to give up. Those lobes are surface hardened and not case hardened.
    I'd insist BMW replaces them before your warranty expires as to avoid the 'goodwill' BS afterward.... YMMV

    My degree in Redneck Engineering has had me wipe a surface like that with Dykem to get a better view of possible surface irregularities (as well as general layout work).

    It was still a problem in 2018.

    I am wondering if those pictures do justice to what you see in person? Did you wipe the oil off the cam lobe before you took the pictures? The angle of the camera, lighting and glare may alter our perspective of what we are looking at.
    If you see no pitting. Feel and see no lines along the lobes, it may just be normal polishing of the surface. That being said, I would expect every wethead cam to look the same. My RS only has 21kkm and I haven't had the covers off with which to compare. Perhaps this weekend if it warms up. If memory serves me right, the cams on my high mileage R80 had a polished look as well. Hopefully its nothing to be worried about.

    Well, two senior techs at two different dealerships have looked at the pictures and feel like I have no problem. I will keep an eye on the cams by checking them at every service and we will see what happens. I have the response from my dealer in an email so I have a record of my concerns. I have a lot of faith in the tech at my dealership. He has gone to bat for me with BMW on a warranty issue when BMW wanted to deny a claim, calls us at home when he needs info and fixed a bike in 20 minutes with a computer update when another dealership wanted us to wait a week to get a part that was not needed. So for now I’ll ride it like normal.
