HIGHER PERFORMANCE SUPER BN SERIES
|
Our Performance BN Carburettors were specially
designed to meet the needs of high horsepower racing watercraft. We have
achieved greater air flow and fuel flow through extensive testing to
provide maximum output for racing engines. Special needle valves and
springs give optimum "pop-off" with larger high and low speed jets for
"first to the buoy" performance. |
