SUPER INTAKE BOOST BOTTLE

Chrome boost bottle is designed for better throttle response and faster acceleration.
Attach the hose to the racing intake. When the engine is running the boost bottle will fill up with atomized
fuel. When the throttle is quickly cracked open from a closed position the intake will suck pre-atomized
fuel from the bottle providing the engine with an added burst of fuel off the bottom when it is needed
without changing jetting which could cause it too run rich (too much fuel).
Good for getting the holeshot when also adding other hi-performance parts.
Requires: Racing Intake (50cc & 90cc
)
