try taking off gas cap see if you have a vent problem also has you scooter been sitting for a long time with ethanol gas if so drain out tank and try to find real gas without it and above 91 octane. But if it been sitting for a while you will need to open carb and clean the low speed jet and high speed jet this isn't a really hard job and there are a lot of u tube videos showing how to do it.
