Re: reason behind turning the fuel petcock off?
I turn the petcock on before I even pull the bike out of storage. lol
I have left it on before and never had issues with fuel pouring out of the carb, but I also had little fuel in the tank. But I use it anyhow. Like one of the others said, if it wasn't necessary, China wouldn't have included it.
