I see some changes in the future of US karting with this. Probably a more structured racing series featuring the x30 engine to compete with the rotax race series, with the help of Skusa. The availability of various tag packages has been dwindling over the years and here’s another indication. X30 or Rotax race series.
Maybe the 2016 CIK engine structure will shake things up in a few years as well. KF is changing back to a more simple package. Back to direct drive and minus the starter. But could be even a few years beyond then for anything to catch on here if at all.
