Yet another way, if you have a compressor, get a gasoline rated hose that is sufficiently long enough, a rag, install the hose in the tank, stuff the rag around the filler body and with a air gun fill the gas tank, this starts the siphon process. when it gets to the end and you can't remove any more add a ounce or two of 90% rubbing alcohol( a couple of splashes) and a pint of fresh gas, start and run to get the last of the bad gas out. The alcohol mixes with the water in the bottom and allows the motor to sort of burn it out, it is water after all. then fill with fresh fuel , meaning you bought it that day, if your not a regular rider and your scoot sits for weeks use Stabil!!!!!it well prevent this.
