FAQs

Is the Champion RN11YC compatible with all Gas Gas models?

It is an OE-quality replacement designed for specific Gas Gas models. Always cross-reference your specific engine displacement and year with the MPN 708.00.46.

How often should I replace this spark plug?

For racing applications, replace at frequent intervals as recommended by your team. For street use, follow the maintenance schedule in your motorcycle's owner manual.

Does this spark plug come pre-gapped?

It is always recommended to verify and adjust the gap to your engine's specific requirements before installation, even if it appears to be pre-set.

Can I use this in a non-racing motorcycle?

Yes, it is suitable for everyday riding, provided it is the correct heat range and fitment for your engine.

What does the 'RN11YC' designation mean?

This is Champion's coding for the specific heat range, thread reach, and terminal construction of the plug. It indicates it is designed for a specific thermal performance envelope.

Troubleshooting

Engine misfires at high RPM

Check the spark plug gap to ensure it is within the manufacturer's recommended range and verify the plug wire connection.

Difficulty starting the engine

Inspect the electrode for carbon fouling or a wet appearance; clean or replace if the plug is saturated with fuel.

Engine pinging or knocking

Verify that you are using the correct heat range spark plug for your specific engine tune and fuel grade.

Pros and Cons

Pros

  • Excellent resistance to high-frequency engine vibration
  • Direct OE-quality replacement for Gas Gas motorcycles
  • Tested for durability in extreme racing environments
  • Promotes consistent engine idle and smooth acceleration

Cons

  • Specific to certain motorcycle engine heat requirements
  • Requires proper gapping before installation
  • Less forgiving than standard plugs if the fuel mixture is incorrect

Setup, Compatibility & Care

Before installation, ensure the engine is completely cool to prevent damage to the cylinder head threads. Verify the gap specifications in your motorcycle's service manual, as the RN11YC must be gapped correctly to ensure optimal ignition timing. Use a high-quality spark plug socket to avoid cracking the ceramic insulator. For maintenance, remove the plug every few thousand miles (or per the manufacturer's racing interval) to inspect the electrode color; a light tan color typically indicates a healthy combustion cycle, while heavy carbon buildup may suggest the need for an air filter service or carburetor adjustment.
