Don't know if this has been posted before. Sorry if it has. Its pretty cool tho. 25fps can't keep up with the speed as it increases. Check it out.

These are interesting too since they show what happens in a rocker arm engine and why you need good valves , springs and the proper stem to guide clearance if you're going to wring your engine out ...

Yeah its very cool to see the real thing in action, rather than just trying to imagine it. Great clips there.
