The Superkarts! USA SuperNationals 27 is one day away from crowning the nine class winners on SuperSunday. Two days of racing were completed on Friday and Saturday outside the Las Vegas Motor Speedway, with all categories contesting the three rounds of heat races and the last chance qualifier for the four divisions big enough to require the downsizing to 40 drivers on the grid. Friday featured a wild weather day from cold to sunshine, downgrading to clouds, rain and strong winds. ‘Situation Saturday’ was a more normal day for weather, as it was the final stint for drivers to position themselves on the grid for SuperSunday.

It has been a near perfect performance for Pro Shifter presented by PSL Karting top qualifier Senna Van Walstijn (Sodi USA). The Dutch driver won all three of his heat races, coming back from third early in the second heat to grab the win after wire-to-wire wins in the first and third. The third was a holeshot win over two-time heat race winner Markus Kajak (NKG / Maranello). Kajak won both his heats on Friday and then ran second to Van Walstijn in their lone battle thus far. They retain their 1-2 positions on the grid for the Final, as does KZ2 world title winner Cristian Bertuca (PSL / Birel ART). Two runner-ups yesterday ended with a P5 in today’s final heat race keeps him in the third slot on the grid for SuperSunday. ‘Super Sub’ Emilien Denner (Sodi USA) arrived to the track Thursday morning, took on 19 minutes of practice and qualified 12th from the slow group. Victory in the final heat of the event along with two top six results promotes him up to the second row for the main event. David Treflov (NKG / Maranello) and Billy Musgrave (Factory Karts) – the highest ranked USA driver on the grid – start from row four in the main event. SKUSA Pro Tour champion Matheus Morgatto (PSL / Birel ART) goes from ninth after having his best finish of runner-up in the final heat of the event.

Reed Cage System Clarification - KA100 and X30
Written by Lynn Haddock - National Tech Director   
Any alteration to the factory intended operation of the reed cage system may be deemed non-compliant. The original statement of the reed screws being a non-tech item was intended to mean the type (straight, Phillips, Allen or Torx, etc) of screw, not to mean an alteration to the size or design could be made. Further, the sizing of the holes in the reed petal hold down plate may be compared to a known stock part to determine legality.
