AKA's New "Junior Performance" Class

Chapter 37 in the AKA rulebook (Junior Piston Port) has been replaced by the AKA's new Junior Performance category - effective immediately.

As a result of the NKC conference, the AKA has now issued an addendum detailing the new class. It will combine existing 100cc and 125cc engines in the one group on the MG Red tyre. Exhaust restrictors and kart weights will be used to regulate performance and thus parity.
