My Diamond Leopard motorcycle and vacuum carburetor have a fuel consumption of 2.7 liters per 100 kilometers. What's the problem?

The normal fuel consumption of Diamond Leopard is about 2.2 liters per 100 kilometers. If the fuel consumption is too high, you can check whether the air filter and carburetor are blocked, whether the mixing ratio is too strong, and whether the damper is not completely closed after hot start. If the car is older, you should also check whether the clutch slips and whether the valve is not closed tightly. Fuel consumption is also related to driving habits, speed and road conditions, so paying more attention to driving methods will help save fuel.
