Omarx646,
Welcome to the site!
Your experience is quite normal. When you run out of gas, for a short time (before running dry) the engine leans out which will speed it up.
When it's cold, the air is more dense, and you get a slight power increase (like a little bit of supercharging). When it's hot, the air is less dense, and you get a slightly "weaker" air/fuel charge into the cylinder, producing a little less power. Gas engines usually run their very BEST on cool, damp days.
Probably this phenomenon is more pronounced with carbureted engines, while electronic fuel-injection maintains a more even air/fuel mix in a variety of temperatures.
Most all of us have the same experience with our scooters, cars, etc.
Ride safe!
Leo in Texas Of course, the scooter is a Longbo 150lbt-12 engine gy6-qmj |

Hi, Im a new member and its my first post. 1. scooter usually revs when the gas is gone. 2. when the general ambient air is cold, engine boost the power, example: paviment hot mid day sun = low power and when paviment is cold = power goes up. I think rejet the carb but first I prefer finding out about the case. thanks and excuse my english.
