He stated its a recreational thing so I'm assuming its an arrive and drive place..
Try working less. You really do not want to be doing much when driving a kart. Do not turn the wheel so much, hard on the brakes, gas, etc Also try taking a different line.
Remember, in those slow ass karts you dont need to hit the brakes. Just let off the gas and turn. That is enough to transfer the weight of the kart to the front wheels. If you hit the brakes (there is only a rear brake) you will transfer the weight back to the rear. So turn in (with out the brake) and feather the throttle in the transfer the weight back to the rear.
