Harleys are designed to understeer - long wheelbase, low centre of gravity, raked out forks - no chance of gripping and/or handling at speed or braking effectively. Having raced non Harley bikes that are inclined to push the front I would say there is a difference between Harleys and performance or sporting bikes. The twain are unlikely to meet. As touring or pootling bikes Harleys work. For the M3W a generalism; pump up the front tyre pressure and wellie it. Generally sorts out the understeer. If your bike is understeering then try dragging your inside knee harder.
