5 karts or more creates a new class but these are the 2014 championship classes also the beauty of the slides is you don't have to change jets so we can adjust with a new slide if we have to. These classes will be modified in 2014 and tightened up as best we can. 206 is a great motor and is growing until its bigger this is my solution. We will do our best that's all we can do since there are so many engine packages it spreads competition thin and weakens karting all together.
