The piston skirts get a dedicated spray of oil.   [thumbsup]

No book will tell you they do, but when you pull the engine apart, low and behold, there they are...

As for the endoscope? video:

Is that a new fangled 3 stroke motor?  [laugh]

The exhaust stroke is missing!!!

The Desmoquattro has piston cooling jets.

What I find very interesting is the inlet flow and velocity at partial valve lift.

you'll  find that all modern ducati's will have an under piston oil jet for cooling. I've just finished a mod to an early 90's engine I'm building that brings the cooling jet to another position on the rear cylinder so that it dosn't hit the crank wheel for 180deg of rotation. This is so that the rear piston gets cooling for 100% of the time not 50%. (newer engines have addressed that problem)

Yeah, I was thinking about that too. Appearances can be deceiving but it looked like almost all of the intake charge was finished before the valve was all the way open.  Maybe it was just more visible at high velocity.
