Engine Tune-Up on a Newer Motorcycle
Just as with automobiles, motorcycles need to be tuned up periodically to keep them operating at peak efficiency.
For our new model tune-up, we replaced only the spark plugs and air filter on motorcycles.
Materials :
- Motorcycle service manual
- Replacement air filter
- Replacement spark plugs
- Socket wrench
- Torque wrench
- Spark-plug gapping tool
- Screwdriver
- Antiseize lubricant
- Dielectric grease
Procedure :
- After unplugging the spark-plug wires, unscrew the spark plugs and remove them.
- Using a gapping tool, gap the new spark plugs to the specifications recommended in your service manual.
- Apply some antiseize lubricant to the threads on the new plugs.
- Install the new plugs and, using a torque wrench, tighten them to the torque specifications recommended in your service manual.
- Apply a small amount of dielectric grease to the contacts on the plug-wire connectors, and reinstall the plug wires.
- Once you've finished replacing the plugs, proceed to changing the air filter. Remove the air-filter cover and remove the old filter.
- Install the new air filter according to the manufacturer's instructions.
- Replace the air-filter cover and tighten it down securely.
