Camshaft failure at 12500 km?

[zoltan]

Bike is a 2018 GSA model, not mine. Bike belongs to a chap on the Romanian FB group, had it from new. Back to the shop for surgery...What can be the reason for this kind of wear out?

Either wrong oil / Low oil or bad case hardening!!!!

Or he wheelies the fecker everywhere??

Hence Oil starvation !

cam lobe not hardened as it should be....

Could be oil starvation. Didn’t bmw have a problem with oilways (or lack of) before? JJH

Soft batch of cams. It happens every once in a while

Do they actually harden them? Reason for asking is that 80's/90's I used to work for a company specialising in performance upgrades for both air and water cooled VW's and the cams on those weren't hardened.

Cranks would be tuftrided but not cams.

Correct, mate had his changed by Jeffries, 17 plate triple black, 13,000 miles. If this was a new shift cam....imagine all the posts!!!!

Had my cams replaced because of poor finish last year, 2016 bike, I think they are plated

Also had the central timing gear and sprocket assembly replaced because of excessive noise

I went through 3 sets of cams on a GSXR750L. Soft as chocolate they were. A known problem with them. I did do big miles on that bike so at the time not many were being changed. Mine were done under warranty back then.

You mean 1991

I had a 1991 750M, the last oil cooled model and then a 1992 750WN, the first water cooled
