What Are the Causes of Motorcycle Stalling?
1 Answers
Motorcycle stalling can be caused by engine overheating and electrical circuit failures. Below are detailed explanations of the specific causes: Engine Overheating: Excessive temperature leads to poor lubrication, causing the piston and cylinder to seize, which results in stalling. Signs before stalling include a gradual decrease in power followed by a sudden stop. After diagnosis, the first step is to check whether there is lubricating oil in the crankshaft case. If the oil level is low or absent, inspect the oil pan or drain plug for leaks. Once the issue is identified and resolved, refill with the specified lubricating oil. If leakage is not the problem, check whether the lubricating oil has been excessively consumed and replenish or replace it promptly. Electrical Circuit Failure: Automatic stalling caused by a sudden electrical circuit interruption will not exhibit any abnormal symptoms in the engine beforehand. Common causes of sudden electrical interruption include loose or disconnected joints, severed wires, or short circuits. For example, a faulty ignition coil may result from loose connections, leading to ignition failure. Inspect all connectors, clean off any oil residue, and increase the clamping force of the connector tabs and sockets to enhance contact strength and ensure stable connections. Similarly, a faulty trigger coil may cause ignition failure due to loose lead connections. Strengthen the soldering of the leads and eliminate any potential cold solder joints.
