The second half of the 2023 California ProKart Challenge was revised due to the arrival of Hurricane Hilary. The fourth stop of the Superkarts! USA regional series in August was scheduled to be a double-round weekend, hosting Rounds Four and Five. Due to the weather issues, Round Five was moved to the upcoming series finale weekend on September 22-24 at the Adams Motorsports Park in Riverside, California.

The change for the California ProKart Challenge finale weekend at the Adams Motorsports Park will feature three days of action. Five rounds of practice will be offered on Friday, September 22. Saturday will host Round Five of racing, including warm-up, qualifying, Pre-Final and Final. Sunday is a duplicate format to contest the sixth and final round of the California ProKart Challenge, including the race-day podium presentation – and new for the series – the 2023 championship podiums.

The 19th season for the California ProKart Challenge has been put to the test as the program enters the second half of the championship chase. What was scheduled as a three-day, two-round race weekend at the Adams Motorsports Park in Riverside, California over August 18-20 became a shortened two-day, one-round event. Hurricane Hilary hit the southern California region on Sunday, forcing Superkarts! USA to postpone the Round Five action scheduled for that day. Round Four was contested on Saturday, with dry weather greeting the competitors at the historic Riverside, California facility.

Max Bore Size Update
Written by Lynn Haddock - National Tech Director   
Wednesday, 23 August 2023 19:00
In recent days we have discovered an issue with the max bore size for the Mini Swift and KA100 engines. In both cases, when using the largest size piston available, if the clearance is excessive (a well-worn engine), there is a chance the stated maximum bore size could be exceeded.

Until further notice (the 2024 fiche factory document) the following maximum bore sizes will be in effect.
  • Mini Swift - 42.21mm (1.662")
  • KA100 - 48.69mm (1.917")

The second half of 2023 California ProKart Challenge is set to begin over the August 18-20 weekend. Competitors will head to the historic Adams Motorsports Park to contest Rounds Four and Five of this year’s championship program in a three-day, double- round weekend. The Riverside, California facility is one of the country’s oldest karting circuits since opening in 1959, welcoming the Superkarts! USA regional program multiple times during its 19 seasons.

The second half of the championship chase begins in Adams, featuring a number of tight point standings heading into the next two rounds. Texas driver and two-time winner John Burke remains at the top of the HRT Driver Development KA100 Senior standings. His lead is only 10 points ahead of three-time podium finisher Ethan Lampe with two-time top qualifier Kane Martin a close third, 67 points out of first. Keagan Kaminski has three wins in the first three rounds to lead the standings in the SpeedSense Motorsports KA100 Junior division. Two-time top qualifier Shea Aldrich is second, back by 154 points with Payton Westcott sitting third in the chase.
