What is the correct procedure for lubricating mechanical control cables (e.g., clutch and front brake cables) on a motorcycle?

1. Disconnect the cable at the lever, attach a cable luber tool, and inject cable lubricant until it flows out of the opposite end of the cable sheath.
2. Spray penetrating oil onto the outside of the rubber protective sheath without disconnecting the cable.
3. Soak the entire cable assembly in a bucket of used engine oil for 24 hours.
4. Drip thick chassis grease onto the exposed inner wire at the handlebar lever and pump the lever rapidly.
