Nick,
I am sure the tracks and shope would provide you an arrive and drive program. Just call them. All of then are very friendly and informative. I have a favorite in SAC Motors–Tim George
Try searching on e-karting news for your questions. The best website and a wealth of knowledge-even a newbie section.
When you are ready to buy:
buy a motor and chassis that are locally supported with information and parts. realize that to get into karting the first yr will run you <$10,000. You got a chassis, motor, safety gear, stand, gas, specific tools, how do you haul one, supplies, etc. Tag or shifter classes new roller (~$$4,000-$5500 tag) Used $2500-$4000)Contact me if you want to talk via PM
