What should I do if the motorcycle refueling door is struggling?

Motorcycle refueling door is difficult, if it is impossible to increase the throttle, or the power to increase the throttle is insufficient, the air filter, carburetor, exhaust pipe, etc. are blocked or improperly debugged; If the throttle itself cannot be screwed, it is caused by the throttle pipe, throttle handle sleeve, carburetor throttle plunger or throttle body being too tight. Sometimes the ignition system fails, etc., which may also lead to the difficulty of refueling and the inability to increase the throttle.

When it is difficult to increase the throttle of motorcycle, you can check whether the air filter, carburetor and exhaust pipe are blocked, clean or replace the air filter, clean the carburetor, check whether the mixing ratio, oil level, oil needle and shock absorber of the carburetor are improperly debugged or used, whether the quality of the carburetor itself is too poor or seriously aging, and whether the carburetor model is not suitable for motorcycle.

Check whether the spark plug is defective, whether the model calorific value and electrode gap of the spark plug are inappropriate, whether there is a problem with the high-voltage package, igniter and magneto of the ignition system, or whether there is a fault with the wiring of the ignition system, resulting in weak high-voltage electricity or high-speed ignition failure, which leads to the difficulty of the fuel filler door. Check whether the cylinder pressure is low, whether the valve and intake pipe are leaking, whether the valve timing is wrong, and whether the gasoline quality is not good. This may also cause the gas door to be laborious.

Check whether the oil is too bad or the clutch is worn and slipping, which will cause the fault that the throttle is increased but the vehicle speed cannot be increased accordingly. If the throttle is too tight, it is difficult to tighten it, it is a problem with the throttle pipe, throttle handle or carburetor.
