Hawk 250 excessive ticking

I wonder if the valves were so tight, and never adjusted for the life of the bike so far, that you had impact on the piston head (slight) from one of them, or both... No way to verify except removing the head, but if it was touching, it could have made the noise.

I know it did NOT go away after you adjusted the valves, but a valve(s) may have damage now, and making a noise? Why would it seem like it is making the same noise, I know...Long shot, but if the lower cam is OK, might be a "next" step?

It's running, so if you catch this before it grenades somehow, you should be able to rescue the engine preemptively.
