There are basically two kinds of karts, water cooled and air cooled. Water cooled is very expensive fast and punishing. The big money makers push this class on unsuspecting newbies so get ready for the hype.
Air cooled is less money, less power and much more enjoyable imho. Some of the best drivers I’ve ever raced with are in the lower powered classes. See if both tracks have an LO206, Yamaha KT100, clone, world formula, KPV or animal class. You could be on the track with good used equipment for under 2k.
