I have my engine kill switch in the off position. I have young children and they are very interested in my motorcycle and want to start it. I decided to start using the engine kill switch in the off position to make sure they couldn't actually start the bike if they managed to swindle my key from my key chain. Ever since then my carbs have started flooding to the point of gas leaking out. I couldn;t figure it out and I still don't understand it. As soon as I stopped turning the kill switch off, the gas leak stopped and no problems since. Any ideas? Has that happened to anyone before? I always keep the petcock turned off when not riding anyways so I don't think that would have affected it. A real stumper.
