Why does a motorcycle jerk at low speeds but run normally at high speeds?

[DiKaden]

Possible causes include a clogged carburetor or improper air-fuel mixture adjustment. Here are explanations for potential engine issues: Engine misfire: This refers to one cylinder in a multi-cylinder engine ceasing operation, which can cause abnormal vibrations and poor acceleration. Professional inspection and repair are required. Engine overheating: After prolonged or aggressive driving, engine temperature may exceed normal levels, triggering the engine warning light. In this case, simply stop and let the engine cool naturally. Severe carbon buildup: Heavy carbon deposits in the engine can lead to poor acceleration and increased fuel consumption, requiring timely cleaning.
