Locating the Drain Plug

- Use a socket wrench or ratchet to remove the drain plug. Be prepared for the fluid to start draining out.
- Place the drain pan under the drain plug to catch the old fluid.
Draining the Old Fluid
Let the old fluid drain completely into the pan. This may take several minutes.
- Once the fluid has stopped dripping, replace the drain plug and tighten it to the specified torque (usually around 30-40 Nm).
Refilling with New Fluid
Now it’s time to add the new transmission fluid.
- Use a funnel to pour in the new fluid. Make sure to use the correct type and amount specified in your manual.
- Replace the filler plug and start the engine. Let it run for a few minutes to circulate the new fluid.
Tips and Considerations
Checking for Leaks
After refilling, start the engine and let it run for a few minutes. Then, turn off the engine and check for any leaks around the drain plug and filler plug.
- If you notice any leaks, tighten the plugs further or replace the gaskets if necessary.
Disposing of Old Fluid
Properly dispose of the old transmission fluid. Take it to a recycling center or an auto parts store that accepts used fluids.
- Do not dispose of it in the trash or down the drain, as it can harm the environment.
Common Mistakes to Avoid
Over-Tightening the Drain Plug
Avoid over-tightening the drain plug, as this can damage the threads.
- Use a torque wrench to ensure the correct torque specification.
Using Incorrect Fluid
Using the wrong type of transmission fluid can damage your bike’s transmission.
- Always check your manual for the correct fluid type and specifications.
