Flaps, slats scooter to 125cc 2 times

Here you will find all the valves strips ... motor scooter 125cc 2 times! Ideal for increasing its power, torque, acceleration, speed, approaching the most of the power system and improving its passage. valves of the slats must resonate more or less belatedly, a soft strip and in low quality (steel clicking ...) leave very early passing the gas mixture in good quantity but bridera (will resonate frequency) too early!
