Choose the nozzle size from the sales drop down list. This item fits the version of these carburetors sold on this site but may not match those on many similar but slightly different versions of the same size carburetors made specially by the Mikuni factory for OEM motorcycle manufacturers. The Mikunioz back board with 1 and 10mm increments may help you with identification but if it doesn’t match up, it wont and if in doubt please call our office before ordering.
