Death Metal Racing gas cap. These fit all Harley models with standard screw in style gas caps. CNC machined from 6061 T-6 billet aluminum. O-ring included to ensure a tight seal. Available with or without a hidden vent which is a threaded screw in fitting with a mesh screen to help prevent fuel from splashing out of the vent or a solid screw in non vented plug. If your tank itself is vented, you will need to select NON-VENTED cap and it will come with a brass plug installed. Right side fill tanks on late model fuel injected bikes have NON-Vented gas caps. If you purchase a vented cap for a non-vented bike, gas will spew out of the hidden vent when the tank is full and the pump is activated when the bike is started. Center fill 08-up touring models use a vented cap. Carbureted bikes can have vented or non vented, it varies from bike to bike. Just depends if the tank is vented or not.  Comes with a carbon fiber insert with double sided tape to install in the center of the cap if you so choose. 4 logos to choose from, or run it without the insert. (If you do not put in which logo you want, you will not receive an insert) WE DO NOT DO CUSTOM LOGOS ON CARBON INSERTS. YOU MUST CHOOSE ONE OF THE STYLES AVAILABLE.  TYPE WHICH LOGO YOU WANT IN THE SPACE PROVIDED BELOW. Logos available are #1, SINGLE LIGHTNING BOLT, DOUBLE LIGHTNING BOLTS, OR DMR initials. These fit all model Harleys that use a screw in standard style gas cap. Available in numerous colors and finishes.
