Why Does Your VN750B5TR-E Stop Working? Here's What to Check
If your VN750B5TR-E has suddenly stopped working, it can be frustrating, especially if you're unsure where to begin. Below, we’ll go through common causes of this issue and offer clear, step-by-step solutions to help you diagnose and fix the problem.
1. Check the Fuel System
One of the most common reasons for a motorcycle to stop working is a problem with the fuel system.
Possible Causes: Fuel tank empty or low: Always start by checking if there’s enough fuel in the tank. Clogged fuel filter: Over time, the fuel filter may get clogged with dirt and debris, restricting the fuel flow to the engine. Fuel line blockage: The fuel line can become clogged or kinked, preventing proper fuel flow. Solutions: Fuel tank: Ensure that the fuel tank has enough gas. If the fuel gauge isn’t accurate, remove the fuel cap and visually inspect. Fuel filter: Inspect and replace the fuel filter if it appears dirty or clogged. This is a simple fix that can restore the fuel flow. Fuel lines: Check the fuel lines for any visible signs of blockage, wear, or kinks. If needed, clean or replace the fuel lines.2. Battery and Electrical System
If your motorcycle isn’t starting or turning over, the issue could be with the electrical system.
Possible Causes: Dead or weak battery: If the battery voltage is too low, the bike won’t start. Faulty wiring or loose connections: A loose or corroded wire can cut off power to essential components like the ignition. Blown fuse: A blown fuse in the electrical system can cause the bike to stop running. Solutions: Battery check: Use a multimeter to check the battery voltage. A fully charged battery should read around 12.6 volts when the engine is off. If the battery is low, either charge it or replace it. Wiring: Inspect all wires for any visible damage, wear, or loose connections. Ensure all terminals are clean and secure. Fuses : Check the bike’s fuse box for any blown fuses. Replace any faulty fuses with the correct rating.3. Ignition System
A malfunction in the ignition system can also cause your VN750B5TR-E to stop working.
Possible Causes: Faulty spark plugs: Worn-out or damaged spark plugs can cause engine misfires or prevent the engine from starting. Ignition coil issues: A defective ignition coil can prevent the spark plugs from firing, leading to a no-start condition. Problems with the kill switch: If the kill switch is faulty or accidentally engaged, the bike won’t start. Solutions: Spark plugs: Inspect the spark plugs for signs of wear, dirt, or damage. Clean or replace the spark plugs if necessary. Ignition coil: Test the ignition coil using a multimeter. If it’s faulty, it will need to be replaced. Kill switch: Make sure the kill switch is in the "Run" position and not accidentally engaged.4. Air Intake and Carburetor
Another common reason for your bike to stop working is an issue with the air intake or carburetor.
Possible Causes: Clogged air filter: A dirty or clogged air filter can restrict airflow to the engine, causing poor performance or preventing it from running. Carburetor issues: If the carburetor is dirty or not tuned correctly, the engine might not receive the right amount of fuel and air mixture. Solutions: Air filter: Remove the air filter and check for dirt, debris, or blockages. Clean it or replace it if necessary. Carburetor cleaning: If the carburetor is clogged, you may need to clean it thoroughly using a carburetor cleaner. If you’re unsure, this may be best left to a professional mechanic.5. Clutch and Transmission
If the engine is running but the bike is not moving, it may be due to an issue with the clutch or transmission.
Possible Causes: Worn-out clutch: A clutch that’s too worn out or damaged will fail to engage properly, causing the bike to stop moving. Transmission fluid levels: Low or dirty transmission fluid can affect the operation of the clutch and gears. Solutions: Clutch inspection: If the clutch feels loose or doesn’t engage properly, it may need to be adjusted or replaced. Transmission fluid: Check the transmission fluid levels and top it up if necessary. If the fluid appears dirty or contaminated, consider replacing it.6. Overheating
If your VN750B5TR-E has been running fine but suddenly stops, it may have overheated.
Possible Causes: Low coolant levels: Low coolant can cause the engine to overheat and shut down. Coolant leak: A leak in the cooling system can result in a loss of coolant. Solutions: Coolant check: Inspect the coolant levels in the reservoir. If they are low, top up with the recommended coolant. Leaks: Check for visible signs of leaks around the radiator and hoses. Repair any leaks before refilling the coolant.7. Engine Timing or Compression Issues
Finally, if your engine is turning over but not firing properly, there may be internal issues like incorrect engine timing or low compression.
Possible Causes: Timing belt or chain issue: If the timing is off, the engine may not fire correctly. Compression loss: Low compression can indicate an issue with the engine’s pistons, valves, or rings. Solutions: Engine timing: Check the timing to ensure it’s properly set. This may require professional help if you're unsure how to do it yourself. Compression test: Perform a compression test on the engine. If compression is low, you may need to consult a mechanic for further diagnosis.Conclusion
To get your VN750B5TR-E back in working order, you’ll need to systematically check each of these systems: the fuel system, battery and electrical system, ignition system, air intake and carburetor, clutch and transmission, cooling system, and internal engine components. By following this guide and addressing the issues step by step, you should be able to diagnose and fix the problem. If the issue persists after these checks, it’s a good idea to consult a professional mechanic for a more in-depth diagnosis.
