These O rings replace those in the Fuel Inlet "T" Piece between carbs 2-3, as well as the fuel rail bobbin pieces between carbs 1-2 and 3-4.

A total of 6 O rings are required to seal the fuel rail on these bikes- all 6 are included in this kit.

O rings are modern "Viton" compound- resistant to fuel and ethanol, specially manufactured to the original Honda OEM sizes.

We recommend replacement of these seals if you are doing any work at all on the carbs of these bikes- disturbing the old hardened seals will create fuel leaks and the original seals were not ethanol resistant to modern petrols.
