Gas Tank Cap for built in tank bike frame

Do you have a SkyHawk built in tank bike frame?    If you do here's the gas cap that fits it.   

These caps are hard to find so we decided to add them in our product line as an accessory item.   It is an EPA certified cap with ventilation and a long lanyard to prevent loss.   

We have a high shipping weight that allows you to order more items and use up the 20 dollar shipping cost.    Just stay under 20 lbs total weight for a 20 dollar shipping cost.
