Just got my SAGA SV last week. My ride is really jerky in a way that the engine braking is so bad (decelerates really fast and sudden, no momentum movement) when my feet of the accelerator during low speed. Even when I press the back the accelerator lightly/slowly, it will jerks abit and moves

Is this common for a new car?

So basically, it will get better after the first service? Because it's really jerky that I'm getting headache from it. I'm no stranger to CVT (Driven Inspira and Honda City '05) but this is way too jerky for a CVT. So, should I raise my concern to SC when I do my 1k km?
