What hose(s) is the coolant coming out of? It shouldn't be coming out the reservoir overflow when it is not full (I am assuming you are checking as this happens, not after the bike had a chance to cool down). If it's coming from the reservoir overflow, check the level as it happens. The first suspect is probably the radiator cap. It's either dirty (needs to be cleaned) or simply faulty (and needs to be replaced). If the cap is good, this would indicate that the bike is overheating, when idling, leading me to believe you have a problem with the thermostat or cooling fan.
