Meet George and Jamie

With the support of his dad, George, Jamie has been racing since age 11. Starting at a local track, the Badger Kart Club, they quickly expanded to racing at regional and national series races.

From the beginning, Jamie and George loved the technical aspects of the kart and engine. George would buy parts and equipment in bulk so that others at the track knew they could come to him for last minute needs. Jamie started building US820 engines at 14 years old.

After working at Franklin Motorsports (originally owned by Doug and Greg Mayr), George and Jamie took over the business in 2005, and continue to share their love for go kart racing with other families.

One of Jamie’s most highlighted achievements are winning WKA Grand Nationals in 4 different classes, and most recently a SKUSA Masters class. Having entered the SKUSA Masters class just for the enjoyment of racing, winning was a source of personal pride and a demonstration of the quality of the equipment and the program that they provide.
