A few weeks ago I reported that my Bet&Win 250 made a slight metallic ticking sound, but it disappeared and I rode it for about an hour. Seemed ok though. Now I realise that the oil was low for some reason even though I changed it a couple months back and it was full at the time. I can't understand why it dropped so quickly in maybe ten uses. Now I can't get the scooter started at all, the starter just grinds but the engine won't turn over. Have I damaged the engine. The dipstick showed very little oil when I checked it.
