Just get a group of people to start that L0206 class, it will grow like weeds after people see how much fun it is.
Most clubs require at least 3 karts to make it a class anyway, and after that it won’t take long to grow. There are already 2 of you, just talk to your buddies or guys at the track and see if they wanna run L0206. This class is already big at most tracks and clubs throughout the country.
Heck I have 4 kart and 2 brand new karts, all L0206.
