It is difficult to accelerate the throttle of motorcycle.

This situation is most related to the carburetor problem. First, carefully and thoroughly clean the carburetor, and check whether the mixing ratio of the carburetor is improperly adjusted, whether the electronically controlled air door works normally, whether there are problems with the vacuum diaphragm and oil needle of the throttle valve, whether there is slight air leakage in the hoses related to the engine and carburetor, whether the spark plug and high-pressure cap are normal, whether the valve clearance is normal, and whether the air filter element is blocked or leaked. High fuel consumption is related to air filter blockage, improper carburetor debugging (such as mixing ratio) and poor throttle. However, according to the current price of No.97 gasoline, it is not particularly expensive to run 130 km for 35 yuan. It is most suitable for Neptune to use No.93 gasoline, but it is not better to use No.97 gasoline.
