How to Solve the Jerky Throttle Response on a Motorcycle?

Possible carburetor blockage, simply clear it. More relevant information is as follows: 1. Check the air filter: Inspect if the air filter is oil-soaked or clogged, whether the carburetor's air-fuel mixture is too rich or too lean, if the fuel level and needle height are improperly set, and whether the electric choke (choke valve) fails to close after the engine warms up, remaining in the enrichment state causing an overly rich mixture. Also, check if the carburetor is clogged, thoroughly clean the carburetor, and clear all passages inside. 2. Check the vacuum diaphragm: Inspect if the vacuum diaphragm is damaged or leaking, and if the vacuum fuel tank valve is faulty, causing gasoline to seep into the intake pipe and resulting in a rich mixture. 3. Check the ignition system: Examine all components of the ignition system such as the spark plug, spark plug cap, high-voltage wire and coil, ignition coil, magneto coil, etc., for any issues, and check if the connections between them are loose, poorly connected, or have open or short circuits.
