Harleys don't mix oil with their gas. Harleys have "dry sump" oil systems; instead of there being an oil pan in the engine, a Harley has an oil tank under the seat. The grade you want is 20W50.
Increase circulation and oil cooling. Not all Harleys have external tanks
some use a dry sump oiling system. This system requires the oil be pumped from a tank.
Typically its either worn or broken Piston compression rings.

When does an oil cooler work? When air is blowing through it. When is the oil too hot? When it is idling in heavy traffic. That is the reason HD doesn't install oil coolers on Harleys, though they will sell anything that you will buy, as that is the business they are in.
