1986 Suzuki VS 700 Intruder will not start
Troubleshooting a 1986 Suzuki VS 700 Intruder That Won't Start
The VS 700 Intruder is a classic, but like any machine, it can have its moments. Let's break down some potential causes and solutions to get you back on the road:
Initial Checks:
Battery:
Voltage: Use a multimeter to check the battery voltage. It should read around 12.4 volts or higher. If it's low, charge the battery and try again.
Connections: Ensure the battery terminals are clean and tight. Corrosion can hinder proper current flow.
Fuel:
Level: Obvious but crucial, make sure you have enough fuel in the tank.
Quality: Old or contaminated fuel can cause starting issues. Consider draining and refilling with fresh fuel.
Fuel valve: Ensure the fuel valve is turned to the "ON" position.
Kill switch: Verify the kill switch is in the "RUN" position.
Deeper Dive:
If the basics check out, let's delve into more specific areas:
1. Ignition System:
Spark plugs: Check for spark. Remove a spark plug, reconnect the plug wire, and ground the plug against the engine while cranking. You should see a strong, blue spark. If not, the spark plugs might be fouled, worn, or there could be an issue with the ignition coil or wires.
Ignition coil: Inspect the coil for any visible damage or cracks. A multimeter can be used to test the coil's resistance according to the manufacturer's specifications.
2. Fuel System:
Fuel filter: A clogged fuel filter can restrict fuel flow. Try replacing the fuel filter.
Carburetor: The carburetor might be dirty or require adjustment. Cleaning or rebuilding the carburetor might be necessary. This can be a complex task, so consider seeking professional help if you're not comfortable with it.
Fuel pump: If the bike has a fuel pump, ensure it's functioning correctly. Listen for the pump priming when the ignition is turned on.
3. Electrical System:
Fuses: Check all fuses related to the ignition and fuel system. Replace any blown fuses.
Wiring: Inspect the wiring for any loose connections, damage, or corrosion, especially around the battery, ignition coil, and kill switch.
Additional Considerations:
Starter motor: If you hear a clicking sound when trying to start, the starter motor might be faulty or the solenoid could be sticking.
Neutral safety switch: Ensure the bike is in neutral. A faulty neutral safety switch can prevent the engine from starting.
Compression: Low compression can cause starting problems. This could indicate worn piston rings or other internal engine issues.
Seek Professional Help:
If you're unable to identify or resolve the issue yourself, don't hesitate to consult a qualified motorcycle mechanic. They have the expertise and tools to diagnose and repair complex problems.
Remember to provide as much detail as possible about the symptoms, any recent work done on the bike, and the troubleshooting steps you've already taken. This will help in pinpointing the cause and getting your VS 700 Intruder running smoothly again.
