InMy Moto Guzzi had a separate sump for the transmission and also had a dry clutch; but I did not use automotive oil to lubricate the engine for at least two reasons:
1. There are additives / detergents in automotive oils that may not be good for a motorcycle engine.
2. Automotive oils have less zddp.

Same with my Can-Am Ryker. It has a separate transmission sump for forward-reverse (ratios change by CVT) and no wet clutch.
Also, 10W60, as specified for the Moto Guzzi and 10W50, as needed for the Ryker at temps above 104 F may be difficult to find an automotive oils.
As for 0W20 or even 5W20 oils, there are many automotive manufacturers having serious oil consumption issues with their engines for which of these weight of oils have been specified.
Changing oil on an air-cooled motorcycle at 3,000 miles can be beneficial.
Using pure synthetic oil is most likely beneficial.
Using oil filter without a bypass valve is questionable.
Using automotive oil to save a few dollars may be costly in the long run.
