Stage6 CNC Boost Bottle / Expansion Bottle with mounting kit for 50-70cc Engines

$39.99

This boost bottle from Stage6 is especially designed for 70cc engines. It has a solid chamber to prevent the airstream from oscillating back and forth through the carbs venturi when the throttle is released, meaning that the airstream is only charged with fuel once which improves pick-up when throttle is re-opened which adds up to lower fuel consumption and better throttle response.
