Freddy,
I am located in northern California so the closest track for me is Infineon. I come from a motocross background so I am very familiar with a manual sequential transmission as well as maintenance for 2-strokes. I’ve never driven shifter kart however so I don’t have any idea what its like; I’ve only driven the Rotax karts that they have for the karting schools at Infineon.
I’m 16, 135 lbs, and 5’9″.
