I am by no means the authority on driving. But I Started driving karts with a non EVO Rotax motor. Throttle application is critical with a Rotax on corner exit. Stabbing the throttle is not what you want. Smooth, roll on of the throttle will help you on corner exit. As far as sliding. I will quote a driving instructor I had at the Bob Bondurant Driving school just south of Phoenix.. “If you are sliding sideways, you aren’t going forward.” Good luck!
