O-Ring - needle jet (nozzle main) Mikuni BS38 CV carbs
O-Ring - needle jet (nozzle main) - Fits: XS1, XS2, XS650, TX 650's (1970-79) with Stock Mikuni BS38 CV Carbs. If this O-ring is dried out, shrunk or damaged, fuel can pass around the outside of the Needle jet instead of just thru the jets center causing a richer carb fuel mixture. Note: O-Ring appears too small but it is correct, install by carefully stretching with pointy needle nose pliers until it just fits over the jet.
