How Does The Lift Force Generated In This Action?

Actually if you like take the steps appart its:

 

Compressing the swingarm and shock absorber

Timing of power of the engine

The body itself actually sort of jumps like you normally would without a bike (same story, compress, use muscles, without a bike you would use your arms aswell)

Knees are used to compress the rear, and to make as much as possible space to extent and to shift the bodyweight towards the top of the rock.

And he hits the fender/rear tyre with his behind when the rear tyre gets on top. Then he pulls hos body forward again. This way less weight has to be ''shot'' into the air.

But it looks like the suspension rebounce and the jumping of the rider's body could only generate 20 - 30% of the whole lift force at most to me.

How does the timing of the engine affects the lift in detail? Doesnt it only affects the forward force?

When somebody do a normal splatter which begins with the both wheel on the ground, I can still imagine the wheelie generates much up lift momentum to the center of mass to the bike. But this splatter begins with the front wheel already in air and he still can lift the bike over a meter 0_o
