The wife and i decided to go for a trip Sunday morning, the fuel guage was reading one bar so I stopped to fill up. We had not travelled far around 4Km when i could feel the bike sliding as i went around corners, something didn't feel right, i said to the wife over the intercom i thought i had a flat, so i pulled up to check. The tyre pressure was fine and everything looked okay. So i got back on the bike convinced i was imaging things. I carried on for another couple of KMs and there it was again, i decided to head for home, the next junction was a STOP sign so i pulled up to a halt and waited around 5 seconds before i pulled away. The bike started fish tailing really badly and i have no idea how i managed to hold it up, i pulled over to the side of the road once i had it under control. I looked down to locate the side stand and could see petrol spewing out at some force all over my leg. I told the wife to get off pretty sharply, and put the stand down. When i looked back to the road junction there was a very large pool of petrol on the Road from when i pulled up. The main fuel line connector from the tank had come off completely by the time i pulled over. In what would have been a 10KM trip i lost over half the fuel in the tank. Most of it washing over the back tyre as i was riding along, hence the sliding around the corners, thank god i was not going that fast. I cannot work out why the clip came off, i rode last weekend with no problem, the bike had not been leaking in the garage, and the only thing i did was fill it up. Has anyone else had the same happen and any ideas as to why it would come off.
