Mikuni Carburetor Main Jet SBN Series Jets

Mikuni SBN series main jets are high-speed jets for Mikuni Super BN (SBN) carburetors. They are also called SBN main jets or small round main jets. The main jet meters fuel at wide-open throttle and upper mid-range, so it has a direct effect on air/fuel mixture, power and engine reliability. These genuine Mikuni jets let you re-jet for changes in altitude, temperature, exhaust, intake or engine modifications.
