Pulled the trigger and bought the blue cap for this base. Base and cap are sold separately. Only con i can think of is that i needed to cut a portion of my oem gas base gasket so it will sit flush on my '04 r6. My oem gas cap was leaking fumes into my helmet while i ride, so im hoping this aftermarket combo will fix the problem. Other than that, it looks super clean! No more keys in order to fill up my tank.
