I purchased an rmz 250 a few months back and to my surprise had everything from pro circuit that you can buy down to the valves. I'm concerned of the wear on the camshafts and if I can apply the service manual specs to test for journal wear even tho these cams aren't OEM specs. The wear can be felt by the touch and is equal on the ex and intake Photo

I would suggest that the cam is worn out and you should also see the wear on the head portion of the journals. Most of the time this was caused by and oil delivery problem.

The word used is galling. The metal on the cam is galled
