Next time you’re revving your engine up.
Just think.
At 6,000 Rpm the valves are seating and opening 50 times PER SECOND. No wonder the darn things float.
I can see the piston and crankshaft spinning that fast because its reciprocating. But valves are pretty harsh up and down movement. And guys complain about having to re-shim their valves to often :rolleyes:
