Overfilling oil is not recommended. If engine temperatures become high enough the pressure will cause oil to leak out of the filter and dirty engine parts.
If it enters into the air box, problems will occur.
When you overfill oil in a lawnmower it will smoke when you tip it sideways while mowing,it has no harm

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.
what model first of all. all HD oil tanks have a drain plug. It is not on the engine as previously discussed elsewhwere here because Harley has a dry sump engine.The oil is held in an oil tank and pumped into the engine then out and back into the oil tank. The drain plug, on the tank will be at the lowest point and generally accessable
This happens if you overfill with oil. Max capacity with a new filter is 6.5 quarts.
