Welcome to karting and EKN. Start with finding local tracks and go out and watch them race. Better yet, if it’s a practice day, wonder around the pits and ask questions. The shifters will look impressive but you’re not going to have the skill set to jump into one of them right now. Look for well populated classes. That will make it easier to find answers. And just because you’ll see a large field in a race, that doesn’t mean they’re all the same class. Also find out what shops people are using.
This site and it’s older version (EKN Classsic) have search functions that will allow you to do research. Or fire away here. Good luck and have fun.
