The AMA 125/500 Nationals went off at Spring Creek in Millville, Minnesota, and Team Honda's Rick Johnson topped both motos ahead of Kawasaki's Ron Lechien. Yamaha riders Keith Bowen and Jeff Stanton were next.
In the 125 Class, hometown hero Donny Schmit, a true rookie, led a Suzuki sweep of the podium, as George Holland and Erik Kehoe followed. Schmit won the first moto by 20 seconds; Kehoe, the current Honda team manager, took the second moto. Series frontrunner Micky Dymond of Team Honda would only finish 13th overall with 6-DNF moto finishes.
