What Causes the Jerking Sensation When Accelerating a Motorcycle?
2 Answers
Motorcycle jerking is mainly caused by the engine and clutch. The ignition, intake, and fuel injectors collectively determine the fuel supply, so weak acceleration is naturally related to these systems. Below is relevant information: 1. Engine RPM: During the break-in period, the engine RPM should be varied frequently, and all gears should be broken in. Avoid keeping the throttle at a fixed RPM for prolonged periods. The purpose is to ensure balanced load distribution across all components, but do not exceed the specified maximum RPM. 2. Oil Circulation: During the break-in period, whether starting from a hot or cold engine state, allow the engine sufficient idle time (3-5 minutes) to warm up, ensuring oil reaches all lubrication points.
I encountered this issue when I used to ride motorcycles. Jerky acceleration is usually caused by problems in the ignition system. If the spark plugs are worn out or the ignition coils are faulty, it can lead to incomplete combustion, causing the bike to jerk during acceleration. I remember once when I replaced a spark plug, the jerking sensation disappeared. Also, check if the high-voltage wires are aged or loose, as this can affect current transmission. Poor ignition can also lead to engine carbon buildup, and if left unchecked for a long time, it may damage internal engine components. So, early inspection can save you a lot of money. A clogged air filter may also disrupt the air-fuel mixture ratio, but ignition issues are more common.
