No no no....All pressure fed bearings come from the pressure side of the pump. The scavenge pump apparently has a bleed hole in the return line to lube the clutch area. Only the oil sitting in the heads can be said to passively lube anything. What is in the motor and not under pressure is draining to where it gets picked up by the scavenge pump and returned to the tank.....
You quoted .4 Liter in the motor at any one time. This is easily accounted for by around 200ml in the filter, plus what's in the heads and what's misted and draining down. When i dry sumped a ZZR1100 for a chair, there was always around 1 liter left in the thing. That was as good as i could get it. Too many nooks and crannies for the oil to get trapped in....
