Does anyone know if its possible to eliminate the floats in the carburators on a 08 gs500f i put the motor on my mini sandrail buggy the gas tank sets below the motor so i had to get a small fuel pump but it starts dumping gas out the front of the carbs sometimes and floods it the fuel pumps just a small one with max psi 4.5 the damn thing shuts off sometimes and sometimes it dont.I was thinking i could eliminate the floats pull em outl and install hose and clamps on the drain outlets on the bottom of the carbs and route them back to the gas tank . I am thinking it would help to cool the fuel pump off better anyways keep it from overheating just like fuel injection systems do.i got the vacumn petcock installed on it im thinking i should eliminate it also cause there is no use for it when the tank is lower than the carbs are or i could just route the "prime " side back to the tank and turn the valve half way between pri and on position to relive extra pressure .So my questions are has anyone else done this before ,will it work, or is there some other fix i can do or is something else the problem
Can't eliminate the floats. The needle valve and seats need to be checked for wear and debris. Replace as necessary.
The fuel system can benefit from a low pressure fuel regulator which will send fuel back to the tank when the needle valve is closed. Using the fuel valve as you describe also can be made to work. Whichever method chosen, they will require testing to find the right setting.
There are also carbureted motorcycles with electric fuel pumps. Those pumps might work better for a simple, non-return line system.
The jets, and thereby fuel supplied to the engine, depend on having a set level of fuel in the bowl. The primary job of the floats is to regulate that bowl level. Unless you have another way of doing that, you need the float valves.
The simple solution would be to relocate the fuel tank, but maybe that's not so simple depending on your setup.
