If a deeper oil pan were made, and a pickup fashioned, could the SOHC 750 be converted to a wet sump engine for for radical aesthetic redesign purposes.
Yes.
Imagine the stock oil tank placed below the engine.
Now just make it the shape you want.
It would still need a vent above the top of the engine.
And the filler neck would need to be taller.
Matter of fact just place the tank under the engine with the filler neck
Going up the side and and two short oil hoses hooked from the tank to the normal place on the engine where it picks up oil and returns oil.
That is one way to do it.
