Thanks, helpful images.
How does this tank connect to the main tank or does in not? In the blurb on their website it says this tank empties first then the main tank. How is this managed?
It is connected to the main tank and does empty first as their blurb says.
On installation the original Honda breather tube is disconnected from the underside of the main tank (once you remove the fairing and lift the tank up to gain access). There is a pretty good You-Tube video of Cory's website that covers pretty much everything installation wise.
The fuel feed line from the bottom of the Camel tank is extended and connected to the metal breather fitting on the underside of the Honda tank.
The Camel Tank breather (at the top of the tank) is extended to exit where all the other breather tubes exit low down on the left of the bike.
Incidentally the Camel tank breather has a gravity type 'roll over' valve fitted, so if the tank is full and the bike tips over the valve will shut and prevent fuel draining out via the Camel tank breather tube.
When the engine is drawing fuel it still draws it from the original factory fitted fuel feed line.
As the level tries to drop in the OEM tank a partial vacuum tries to form, but as the breather is connected to the fuel feed line from the Camel tank, the main tank draws fuel into itself by the original breather fitting thus equalising the pressure and topping up the main tank.
The Camel tank is permanently connected to the main tank. Therefor it is the first tank to be emptied. During the time the 6.5L Camel tank is bing used you see full on the bikes fuel gauge at all times. As soon as you see the fuel gauge drop, just one bar from full, you know that the Camel Tank fuel has been used up and the main tank is now drawing air through it as it depletes its own fuel level toward empty. The OEM fuel gauge always gives a trues reading of the fuel in the main tank.
The only way you have of gauging how much fuel remains in the Camel Tank is to open its cap and look in.
