Complete transmission kit of Naraku components, all tuned to another. Since Chinese-built scooters are not kitted with top-end components out of the factory, this is the easiest way to overhaul the transmission without expert help. This negates any restrictors. Top speed and drivability on hills is improved, meaning higher top end and better acceleration!
