Does anyone know the size of the 3rd Gen fuel petcock o-ring? My bike was smelling like fuel all day on my ride, and I got home and could not find a leak anywhere........I kept smelling gas and looked in the garage and the tank surrounded by a puddle of gas. I'm not sure if the riveted plate on the petcock is leaking, or the o-ring. Honda no longer sells the o-ring by itself, and the petcock/o-ring combo is $84......I can measure it, but it would be great if someone had one to measure to save me
