The 2024 Idaho Spud Cup is in the history books, 4 time SKUSA Super Nat’s champ Billy Musgrave taking the win in the premier class of the weekend, and it was not a shifter.
Billy changed his program up and raced a Doug Fleming tuned Briggs & Stratton single speed to victory winning a $5,000.00 pay check in the process.
Billy and his Factory Karts crew have been none stop testing for the past 3 years, from kid kart to shifter kart chassis and everything in between.
Billy nailed the performance of the Factory Karts L206 chassis last year, we have had racers winning on it all year long all over the country.
Thanks to everyone who has been behind us since Billy and I started this journey.
