Ok so I went for a ride, middle of the ride a really bad grinding noise happened. Scared after just replacing my clutch, I shut the bike off. When I started it up again, noise was gone. So I rode it back to the truck real easy and went home. Tore the valve cover off, and I think I found what happened. Theres a ton of metal shavings in the head, and the grinding seems to be on the cam. Is that supposed to be a bearing or something? See below in the pic.
