Took the cam out and the pin had noticeable wear to it. Easy job to replace. Cam and bearings will cost you a little over 2 hundred US. Good luck!
At 27,000 kms, I would also be inspecting the cam follower bearings. From what I know now, I would just be replacing the inlet follower bearing at 27,000. My inlet bearing was totally shot at 27000. I know others have managed to go longer than that, but it's cheaper buying a new one than having one let go and destroy the top end.

I just bought the whole follower with the bearing pressed in by KTM than messing around with punching and hoping I had done it right.
