Anyone Check Their Valve Clearances?

This is an outstanding engine design, good for decades IMO.

Below is a link to an article I found about all the different valve types used in motorcycle engines. For "shim under bucket" valves the guy who wrote the article stated that as the miles pile up valves will tighten and it's better to have loose valves than tight valves. A quiet engine is trouble. Perhaps this is one reason why the Yaris engine is so noisy? Bronsin, is the info in this article been your experience with valves in general? Thanks!
