Overhead cams at 14,000 rpm

S1000RR engine cut away with running engine.

 

Crazy to think that pneumatic valves go well beyond that...

 

That's to fast for me to even think shit, and that's in a 4 stroke.

 

Really makes you appreciate just how important good oil and regular changes are watching that not to mention correct valve clearances

Cheers Lint for posting that

 

Many years since I have seen that vid but it still boggles the mind

 

You don't see it in this video but think about piston. The piston has to change direction 2 per revolution!

 

And the crank's turning at twice the speed of either cam...

 

Makes me glad I use the best synthetic oil I can buy and change it early. Great post, I enjoyed the chit out of that and probably annoyed my mother in law ound: eace:

 

Now for the VFR vid. Hell, nobody out there knows what a VFR is, generally speaking........

 

Wow that is cool as it gets. Ever since I owened my first BMW ( '95 325IS 188hp stock w/ M series trans and suspension package ,140mph top speed at redline) I have always wanted a BMW bike , they caught my eye in my mid 20's after the early vfr's originally sparked my interest in bikes.

Hard to believe the abuse some of these motors take.

 

Cool how the spring and retainer start to spin around the stem at about the 2:00 mark. I've watched it a couple times now. Neat stuff! Thanks for posting.

 

keep in mind that cam is actually going at 7000 rpm, though the engine is at 14000. Pretty wild stuff, still.

 

Huh, found this in the youtube sidebar. A look at the head from below.
