Secondary throttles eases transition from fully-closed throttle to off-idle smoothness. Can be sudden with jerking. You can disable it and if engine-response still smooth, leave disabled.

To smooth jerking without 2ndaries, you can use non-linear throttle-cam. First 5-10 degrees rotation pulls on cable very little. Then pulls more cable for same rotation-angle from then on.
