I'm a first timer too
 It's amazing the springs work at that number of compressions. |

Yep indeed. A really groovie one to watch would be a ducati desmonic valve where it is mechanically returned instead of by spring. Ducati people are welome to correct me as my knowledge is pretty out of date. I was remmembering a Ducati 450.
