92270000: SI Carb Spacer Float Chamber, 3mm SERIE PRO
This genius little spacer kit comes from SeriePro. It's for all SI carbs 20/20 up to 26/26. It raises the float cover 3mm to allow for fuel to be stored in the float chamber so you are less likely to run out of gas at wide open throttle. It also has a spacer for the air filter to raise it since the float cover is raised. It's recommended to use to float bowl gaskets, one above and one below the spacer, with bottom one cut out the center to prevent interference with the float.
