I was holding the throttle steady then the bike jerked me around pretty violently. Ended the days practise then and there.When you folks are saying 'surging' do you mean minor hunting of the rpm when below 4K with steady throttle? (IE: when not under acceleration or engine braking)
Just trying to clarify what people are describing. If we are talking about minor throttle hunting, that's something different.
Surging is when the throttle body actually moves spontaneously with a large action. Hunting is when throttle body flutters without significant input.
