The manual of my 2004 Vmoto scooter says that the fitted 5.2 litre tank should last between 150 and 250KM depending on the conditions (eg. riding up hills, always at top speed etc.) However, at the moment I am only getting around 75KM before the gauge is back on empty. That is less than half what the manual says. I have noticed that I am using alot more oil aswell. The scooter has only done a 2500km so I think that this is rather odd. Any help and advive would be much appreciated.
