Question 2012 14r Cam Lobe Wear... Normal?

Working on a guys 2012 ZX14R with 23k miles and checking valve clearance and he said the last owner may have very likely not changed the oil for way to long.
Just curious if others notice the same thing on their 14's or if perhaps this wear could be attributed to the 1st owner.

Thanks in advance.

NOTE: The blue shows up stronger in some of the photos then it actually is. The lobes do have a blue tint, but not royal blue. More of a blue/gray...

Those look a little wiped, man...which may lead you to speculate on the durability of the main and rod bearings, over the long haul.

It really looks fairly clean in there. Maybe he wasn't running a high grade motorcycle specific oil?

There ain't a lot of valve spring pressure in ZX14Rs so, it's surprising to see any wear at all here. Any wear on the peak of the lobe makes the cam junk in an MC app.

This is the first report of lobe wear on a 1400 that I have seen in 9 years. I wonder what the bucket surface looks like?
