FAQ
Q
What are the reasons for difficulty starting a motorcycle?
A
Possible reasons include insufficient battery power, aging or carbon buildup on the spark plugs, abnormal fuel supply, and starter motor failure. It is recommended to check the battery voltage, clean the spark plugs, replace the fuel, or contact a technician for maintenance.
Q
What to do if the motorcycle idles unevenly?
A
It could be issues such as a clogged carburetor or fuel injector, a leak in the intake system, or a faulty spark plug. You can try cleaning the carburetor or fuel injector, checking the sealing of the intake pipes, and replacing the spark plug if necessary.
Q
What causes a motorcycle to suddenly stall while driving?
A
Possible reasons include fuel line blockage, ignition system failure, engine overheating, or circuit issues. It is recommended to check the fuel supply, spark plugs, and ignition coils for normal operation, and ensure the engine temperature is moderate.
Q
What should I do if the motorcycle brake performance deteriorates?
A
It may be due to worn brake pads, insufficient brake fluid, or air in the brake system. You can check the thickness of the brake pads, replace severely worn brake pads in a timely manner, and check the brake fluid level. If necessary, bleed the air and add brake fluid.
Q
What are the reasons for the increase in motorcycle fuel consumption?
A
It may be due to insufficient tire pressure, aging spark plugs, carbon buildup in the fuel system, or improper driving habits. It is recommended to regularly check tire pressure, replace spark plugs, clean the fuel system, and adopt a smooth driving style to reduce fuel consumption.
Q
How to adjust the tightness of the motorcycle chain?
A
Generally speaking, the tightness of the chain should be maintained within a range of 10-20mm of up and down movement. Being too loose or too tight will affect driving stability and the lifespan of the chain. When adjusting, it is necessary to loosen the rear wheel axle nut, then make fine adjustments to the chain adjustment screw, and after reaching the appropriate tightness, tighten the nut again.
Q
What should I do if the motorcycle engine temperature is too high?
A
Possible causes include cooling system failure, insufficient or poor quality engine oil, clogged air filter, etc. It is recommended to check whether the coolant or engine oil is sufficient and to change them regularly, as well as to clean or replace the air filter.
Q
Is it normal for a motorcycle exhaust pipe to emit black smoke, white smoke, or blue smoke?
A
- Black smokePossible incomplete combustion of fuel, need to check the carburetor or fuel injector.
- White smokeUsually caused by water vapor in cold weather, but if it persists, it may be coolant entering the combustion chamber.
- Blue smokeMay be oil entering the combustion chamber, need to check if the piston rings or valve oil seals are damaged.
Q
How often does a motorcycle battery need to be replaced?
