1973
It was a rare (for back then) Saturday outdoor national, held on the infield of Pocono International Speedway, and Suzuki got its first sweep in AMA Pro Motocross history. It was also a three-foot format, and for the first two 500 motos Yamaha's Pierre Karsmakers was the leader, but he bent his shift lever in the third moto and ended up almost a whole lap down. He would reach 14th, but his 1-1-14 scores did not match the 2-2-5 of Suzuki's Mike Runyard. Finishing second was New York's own Robert Harris on a CZ.
In the 250 Class, Suzuki's Rich Thorwaldson was the overall winner, followed by another native New Yorker in Kawasaki's Jimmy Weinert and Husqvarna-backed Bob Grossi.
Here's a shot of the Pocono track, and if you look closely, you will see a glimpse of Gary Bailey in front of Frank Stacey, and that #157 is Gear Racewear's John Ayers.
1974
At Moto-Masters Park in Mexico, New York, Kawasaki's Jimmy Weinert and Husqvarna's Marty Tripes were the winners of their respective classes at the AMA 250/500 National. Weinert finished ahead of three Maico riders: Steve Stackable, Rex Staten, and Gary Chaplin. Tripes bettered Can-Am's Gary Jones, the reigning series champion, and Yamaha's Tim Hart and Pierre Karsmakers.
