Motorcycle Repair: leaking overflow on 94 cbr 600, vent hose, carburator

Question
i just bought this bike two weeks ago. it only leaks when filled all the way , but from INSIDE the tank. i believe the overflow has a hole  in the steel tubing inside the tank. is this possible and how can it be fixed?  thanks

Answer
Jim,
im not to sure about an overflow are you saying its coming from the tank are yur carbs are overflowing . If its the tank then i would say its your return line thats leaking.If its the carburator drain hose, are overflow then i would clean the carbs out real well also your carburator floats could be sticking im not sure where exaclty you are seeeing the overflow..or you might want to clean out yur vent hose leaving the tank, if its clogged you will get this affect.I hope i have been helpfull please feel free tocontact me o.k.

P.S please leave feedback for me
