Hello all. Hopefully get some help here. So I went away a month ago for the military so my bike sat for a month. I had manual petcock turned off( was replaced 2 mo. Ago). I came home and found bike almost completely empty from sitting. I had approx. a gallon of fresh gas I put in and with fuel valve shut off, pours out of the bottom of the carb. Is my almost new petcock bad or is it something to do with carb? Please help. Bike is a 2000 nighttrain with rsd intake and vance &hines side shots. Any help is greatly appreciated.
