The Mikuni MK-BN38/44SPR watercraft carburetor rebuild kit contains all the necessary genuine Mikuni components to rebuild your Super BN38, BN44, or BN46 SPR series carburetor.  Includes genuine Mikuni gaskets, O-rings, screws, and clips.  Because of the variances in models this kit does not contain any jetting, that is available separately and linked below to our store.  It is best to verify your actual jet size before ordering jets.  See the parts list and diagram below, ALL included parts are circled and listed.  Model applications are also listed below.
