I would definately drain your tank.
You should also change your spark plugs and fuel filter, Oh yea, and also drain your fuel bowls.
Oh, and no I've never done it. Being a Chemical engineer, I understand the difference between the different fuels and consider it rather important to put the correct fuel in my vehicles. Therefore, I pay close attention at the fuel pump. Fueling a vehicle, particularly a motorcycle where there is no check vavle, is an extremely dangerous proposition. I am constantly surprised that more people aren't killed at the gas pump.
