20 Most Recent 1998 Honda F6 C Valkyrie Questions & Answers

Hello! If your 1998 Honda F6 C Valkyrie is experiencing a no-spark issue despite having new plugs installed, there are several potential causes to consider:

1. Faulty Ignition Coil: The ignition coil is responsible for generating the spark needed to ignite the fuel-air mixture in the engine cylinders. A faulty ignition coil could result in no spark at the plugs. You may want to test the ignition coil for proper functioning or consider replacing it if necessary.
2. Faulty Ignition Switch: A malfunctioning ignition switch can disrupt the flow of electricity to the ignition system, resulting in a lack of spark at the plugs. Check the ignition switch for any signs of damage or wear and consider replacing it if needed.
3. Faulty Ignition Control Module (ICM): The ignition control module controls the timing of the spark and ensures that it occurs at the right moment. If the ICM is faulty, it may prevent the ignition system from producing spark. Testing the ICM or consulting a professional mechanic may be necessary to diagnose and address this issue.
4. Electrical Wiring Issues: Inspect the electrical wiring connecting the ignition system components for any signs of damage, corrosion, or loose connections. Faulty wiring can disrupt the flow of electricity and lead to a lack of spark.
5. Battery Voltage: Ensure that the battery voltage is sufficient to power the ignition system. A weak or discharged battery may not provide enough power to generate spark, especially after being stored over the winter months. Consider charging or replacing the battery if necessary.
6. Kill Switch or Safety Interlock: Check the kill switch and any safety interlock mechanisms to ensure that they are not inadvertently preventing the ignition system from functioning properly.
7. Fuel Delivery Issues: While not directly related to the spark issue, it's worth ensuring that the engine is receiving an adequate supply of fuel. Check the fuel system components such as the fuel pump, fuel filter, and carburetors (if equipped) for any issues that may be affecting fuel delivery.

If troubleshooting these potential causes does not resolve the no-spark issue, consulting a professional motorcycle mechanic or an authorized Honda service center may be necessary to diagnose and repair the problem effectively. Hope this helps! Kindly, Jordan

This answer above was perfect and allowed me to fix my 1999 Valkyrie in about 30 minutes! And tapping the carb bowl did seem to free up the valve! Thank you! Copied and pasted from above: Been there done that, Carb needle stuck in the open position. Do NOT try to start it this way as if a cylinder fills with fuel it will hydrolock and cranking the engine can break expensive things. If you need to crank it pull the 3 spark plugs on the effected side and crank it over to remove the fuel from the flooded cylinders. This may require carb. removal and tear down if tapping on the carb bowls doesn't fix it. Same thing happened to my 1999 Valk. Interstate.

Change fuel and air filters.

missing at high rpm indicates an electronic problem could be a coil breaking down , low voltage for the ignition control module , bad ground wire /[point it could also be lack of fuel from insufficient fuel supply or incorrect float level

did lots of oil come out of dipstick hole ?

first check the fuse, if good turn switch on jump starter,if it works you need new starter
