Having run the bike and then pushing the slider from on to off the Slider decided it would be a good idea to come out of the tap completely. The button on one side came off so there was nothing to stop it. I had to watch all the fuel pour out and there was nothing I could do about it. Ha Ho. It seems this is not an unknown issue and the idea seems to be to tap the slide where it connects to the slider button slightly so it just will not come out.
