Hi Saturday we had fine weather, so we went out riding in the woods and I've stalled it (426) while climbing on a steep hill in 1st. It stopped with a loud pop. Did restart very-very hard, and you could hear that the engine isn't running right anymore. It idled, but it didn't rev, you could only crawl with it in idle, or a little bit over idling. I suspected that the camchain jumped and took some pictures, I think my intake cam is 1 tooth off. Should I replace the camchain, or this is a possible risk that anytime could happen when stalling under heavy load? I think in the moment of stalling, the engine rotated a bit backwards, that's why it popped and the chain jumped on the intake cam. And look how my exhaust cam lobes look, is that a problem? The surface is flat, it just looks tesselated.
