What is the reason why the accelerator of scooter is boring?

There are many possible reasons why it is boring for a scooter to step on the gas pedal. Common ones are:

1. Air filter, carburetor or electric fuel injector and exhaust pipe are blocked;

2. Improper debugging of carburetor, failure of mobile concentration device, or aging and poor quality of carburetor;

3. The transmission belt and pulley of the transmission system slip, and if there is a slider, it may be broken;

4. Wear of cylinder block, piston and piston ring. Air leakage caused by too small valve clearance or lax closure;

5. The valve plunger and camshaft are worn, resulting in insufficient intake and exhaust;

6. The ignition timing/valve timing is wrong, the quality of gasoline is not good, and the failure of ignition system parts leads to insufficient high-pressure strength;

7. If it is an EFI motorcycle, check whether the relevant sensors and their circuits are faulty.
