Just in the last stages of finishing re-building my 1981 CB650 Custom and have hit a snag. The old tank was badly rusted so I found a replacement that looks identical. I've had it resprayed and have now found that the original petrol cock assembly has a larger thread than the outlet on the tank. The outlet on the new (replacement) tank has an external diameter of 18mm and internal diameter of 10mm. Does anyone know what petcpck assembly will fit?
Thanks in advance for any help anyone can offer
