leaking out of the carb? from the tank? from the fuel line? out of the tires? ok so the last one was a joke but wheres the leak coming from. if it leaks alot out of the carb while you are riding it could be that the float is stuck.

could be a few things the float inside the carb could be stuck, there could be dirt in the needle valve assembly or the needle valve assembly could just be worn out. i say tke the carb apart and give it a good cleaning, its not as scary in there as you would think just wen you take something apart remember how it goes

The same thing happened with my '03 KX125 ... gas kept flowing through the overflow hose on the carb (bottom).

I replaced part 16030 on the diagram (this part is actually a two piece capsule that includes the float valve and seat). Don't forget the o-ring (part 92055B), because this may be the part that's causing the problem - when this o-ring gets old and shrinks, gas can flow around the entire assembly. This o-ring is on the outside of the seat assembly (this is not clearly shown in the diagram).
