Cam lobe wear

[dravnx]

BMW replaced the shaft on my 2018 last fall because it had over 36k mi. (42k actually). Never felt any difference but there might not have been a problem with my existing shaft.
Got the bike home and decided it was time to do a valve check. Pulled the valve covers and discovered that the cams were bad. A couple were worn down to nubbles. Fortunately, I had an extended warranty. They replaced all the cams and rockers.
The shop observed that one of the forks was leaking. I had just replaced the fork fluid and I think that there was some residual fluid on the forks and it was not actually leaking but hey, they replaced the seal under warranty so that was OK.
The shop also said that my starter was on it's way out because it made a "whining" sound when it was disengaged. Huh? They also replaced it under warranty.
My point is that shops love to do warranty work. It's easy money.

Any chance of photos?

Here’s a pic of some camshaft damage. This was from Sept of ‘23. One of the many bikes Boxerflyer serviced that day.

I'll bring one of my ruined cams to the September meet up. It's a whole lot worse than that. Boxflyer fixed me right up (at his house no less).

Yup, that's classic Boxflyer. Are you bringing it to FART?
