FAQs

What is the factory gap for this plug?

The Champion RL78C is designed with a 0.5 mm gap.

Is this plug pre-gapped?

While it is manufactured to high standards, it is recommended to verify the gap with a feeler gauge before installation.

Can I use this in any motorcycle?

No. You must cross-reference the RL78C with your motorcycle's owner's manual to ensure it meets the required specifications for your specific engine model.

How often should I replace this spark plug?

Replacement intervals vary by engine type and usage. Refer to your equipment's maintenance schedule for the recommended service interval.

What does the fixed terminal mean?

The fixed terminal is the solid top portion of the plug that ensures a permanent, secure electrical connection with the ignition wire connector.

Troubleshooting

Engine hard to start

Verify the spark plug is tightened correctly and the ignition wire is securely attached to the fixed terminal.

Rough engine idling

Check the electrode for carbon fouling or debris and verify the 0.5 mm gap is still within specifications.

Engine misfire

Inspect the spark plug ceramic insulator for cracks and ensure the connection to the ignition coil is clean and free of corrosion.

Pros and Cons

Pros

  • Meets or exceeds original equipment specifications
  • Consistent spark performance under standard loads
  • Durable construction for long service life
  • Engineered by a reputable brand in ignition technology

Cons

  • Fixed terminal may not suit all custom ignition setups
  • Requires manual verification of gap compatibility
  • Limited to specific small engine and motorcycle applications

Setup, Compatibility & Care

Proper installation is vital for the longevity of your ignition system. Ensure the engine is completely cool before removing old plugs to prevent thread damage in the cylinder head. Use a spark plug socket to carefully thread the plug by hand until it is seated, then tighten to the manufacturer's specified torque settings. Avoid over-tightening, as this can strip the threads. For care, inspect the electrode during regular service intervals for signs of carbon buildup or excessive erosion. Always confirm that the RL78C matches the heat range and reach required by your specific engine model before beginning the replacement process.
