I would suggest attending a race or two if possible, and talk to folks in the pits. There are shifters, TaGs, and good ol Briggs 4 cycles… it kind of depends on where you want to race. Have you been to any kart races? http://www.ekartingnews.com has a “new to karting’ link on their front page that has some information. If you have more specific questions, I am sure you will get more response to your inquiry. Feel free to email me directly at [email protected]. Good Luck!!
