There is a separate connector from the bike's battery to the tongue battery. The bike will top off the AUX battery while I am riding.
Wouldn't it be nice if HONDA or some aftermarket genius came out with a high quality AUX fuel tank that would be blow molded to fit snugly and precisely inside of the rear trunk? You could raise up the lid, slip this bad boy into the rear trunk, and have maybe ... four gallons? of extra fuel. A quick connect FACTORY fuel line connection could be added to act as a filler-on-the-go. So when your gas gauge reads empty, you push another button
to open an electronic valve. The fuel would simply trickle down to your main tank via gravity, and would automatically shut off the fuel flow when the existing fuel level sensor reached say ... 95%, to allow for slow reading of the fuel level sensor. A flow meter could tell you the approximate quantity of fuel remaining in the AUX tank, along with a calculation of range.
AUX Fuel Tank Remaning: 1.4 Gallons - AUX Range 62 miles
Hell, if you didn't want to give up the ridiculously small rear trunk space on the new Wings, even an external tank
shaped to compliment the bike's body lines, in bright fire engine red, that securely fastens to the rear trunk rack could carry two or three gallons easily. For an IBA ride, you could use BOTH, and probably have a range of 400 miles or more.
Am I asking for the world here?
