Reply To: Fuel pouring out of breather hose – 2006 gt650r
Tap ? = Disconnect the tank and does fuel still pour out ?
Pump ? = Disconnect the pump from the carb => does fuel still shoot out ?
It could be trying to burst the floats open and this possible chance the bike will be hydrolocked (fuel inside the oil & piston walls) , so make sure the above are good first , before progressing further. (Don’t bypass the pump no matter who tells you)
There is an ancient trick of using a “clear hose” attached to the float bowls , and seeing if the fuel level inside the hose is heigher than the carb markings , and if so, then you have float issues (float valve jammed , float valve o-rings leaking fuel past , floats bent too high or too low , or may simply need a new float valve replaced as part of rebuild kit. but it will test your patience but you want to be sure the carb is faultless.
You can do this while carb is on the bench and feed it auxilary fuel hanging from the ceiling , just to test before fitting it all back to the bike.
No fuel should overflow unless the bike fell on its side. If the bike fell, then yes the fuel should overflow out to protect the engine cylinders.
Let us know how that goes , i hope i made sense!
