Boost Bottle Malossi MASCII Viton recovery lung

This is a Malossi vacuum chamber (lung), originally designed for 125cc engines but also adaptable to tuned engines of smaller displacement. Only available in Viton version.
Its main advantage is that the mixture, once the reed valve is closed, does not return a second or third time to the carburetor, but instead goes to the Boost Bottle connected between the carburetor and the reed valve.
In this way, the mixture does not become too rich, fuel consumption is lower and gas exchange is much more efficient. Highly recommended for large carburetors that tend to become flooded at low revs.
