Ok,bike runs,but after it has ran for a bit and warmed up,I´ll shut it off. Here´s the riddle. After it sits for a short time. About 30 min. Gas starts dripping from the carb overflow tube for a bit,then stops. What could make it do that?I just don´t get it!Could a bad float make the gas come out like that after it has ran then sat for a bit? I have changed the needle,fixed a vacuum leak on the other carb,tried adjusting the float,put new jets in,checked the overflow needle for leaks. Help please!
