Puch tweak.
Reverse the seat bracket so that your seat is now approx 2.5 inches forward. likewise adjust your handlebars to compensate.
You've now put a very substantial percentage of the weight of bike and rider (you) forward a not insubstantial amount (considering the ratio of you/moped).
This puts the center of gravity much closer to the ideal.
Steers and handles more nimbly.
