Larry, many of your observations are very well founded. Karting has struggled with these issues since its inception. One of the biggest reasons is there is very little money to be made in karting and everyone is fighting and clawing for every dime they can get.
As far as where to start, I could type for hours and still not answer all your questions. I suggest that you call me at the shop when you have time and I would gladly answer any questions. I do not sell karts, I manufacture parts that fit in just about all karts. My sons have raced in Colorado for over 8 years and we have raced every class from Junior 1 Briggs flat head to Tag to Pro125 shifters.
