Without digging into it, one way to tell (but definitely not a science) is a complete lack of valvetrain noise. Contrary to what some people believe, some valve noise is desirable. It means the valves aren't too tight, which is a very bad thing.

Speaking for myself, if there's any question about the state of my valves, the valve cover comes off and the feeler guage comes out. There's a range of measurements that the distance between the cam lobe and the lifter should fall within. If it's tigher than spec'd, eventual harm will come to the engine. Remember that valves tighten over time, not loosen, and neglecting them will cause damage to the head.

I believe the ZX bikes have shim under bucket systems, which I haven't tackled yet because the cams have to come out. I much prefer screw & locknut (older Kawasakies and the Ninja 250 up to 2007) due to its simplicity, but it looks like that's a thing of the past.

The problem is the valves tighten over time. So you would not get much noise. But it could bend a valve so, if you don't know when it was done last, then I would check them.
