Wet sumping, a different approach

I used to own an Aprilia RSV Mille 1000cc V twin.
I used a dry sump system with a separate oil tank. The difference was the positioning of the oil tank at crankcase level. It could only drain into the crankcase until the levels equalised, so no danger of starting without oil.
Maybe worth thinking about when building a "special"

It’s a brave man who experimentally reduces the head of pressure feeding his Norton oil pump.

The rudimentary design of the Norton oil pump is designed to push liquid, not draw it. Design specs indicate gravity feeds the pump.
No offense amigo and I have never tried said setup so my observations are only speculative, but if your modifications are not properly implemented methinks bad things will happen to a bunch of friction bearing surfaces in your engine.

I would rather put up with the relatively minor inconvenience of sumping over time but be reassured I have positive pressure at the pump intake.
