3.5 quarts with filter change
Sunoco, makes Harley Davidson engine oil
Certainly. But Harley Davidson Syn 3 is recommended for 5,000 mile oil change intervals, and AMSOIL MCV is recommended for up to 10,000 miles up to 1 year. If you mix them, then AMSOIL recommends changing at 5,000 miles.
I am not sure of viscosity, but if you have Harley Davidson on your fuel tank, you should use Harley Davidson lubricants. H. D. primary and trans lube or H.D. 20/50 synthetic motor oil will work just fine.

On the ride side of scoot ,, there is a rubber hose you will see with a plug in it,, below the oil tank .. Just undo the hose clamp an pull plug ..

5w30 fully syn oil.
100% synthetic will not go bad by itself. What makes 100% synthetic oil bad is basic oil filtration. The oil filtration system on a car is not very efficient, therefore allows the oil to get dirty. Once the oil gets dirty, the oil does not fare as well. There are brands of 100% syn oil that only require a 1yr/25,000 mile change (with guarantees-- google search 25,000 mile oil change). There are others (on store shelves) that require a 5000 mile change, but charge the same price as the 25,000 mile oil change. Make sure to look for 100% syn. There are syn oils out there that are actually a "synthetic blend", which means it's part syn, part conventional oil.
