I agree with Don. Everything I have seen on the minimax vs. a WKA animal (emphasis added) shows about 30% extra horsepower for the minimax at sea level. Given that Junior 1 is already crowded (we had 11 karts last sunday which is still a large field so late in the season) and junior 2 isn’t, why not run a separate minimax class with junior 2?
