This is an old thread, but I’ll add onto it.
I still have the same general idea, buy the kart and safety equipment and do some local races before moving to bigger, regional championships. I have decided on the KA100 engine and am buying a kart in a few months, once I have the cash for everything. First, I am planning to run a series at a local track and also do some more races around Ohio. I plan on spending around 6k on a kart, safety equipment, etc. This is mostly just to get used to karting.
Then, after a year or so of experience, I plan on entering a more professional series such as Route 66 and have a budget of around 8k for my first season of that.
That is where I am right now, any help would be greatly appreciated.
