CAM JOURNAL REPAIR
Advanced Machining Services offers a cam journal repair service.
Bent valves, seized cam, yeah, this is a common problem with the newer 4-strokes. Don’t through away the head just yet though. In most cases it can be repaired.

This cam journal has a good amount of damage.
The cam was seized to the head.

A little closer look you can see damage, pieces of
missing aluminum can actually gall to the cam.
