Tools and Parts Needed

- Drain pan
- Funnel
- Gloves and safety glasses
- Rags or paper towels
- 10W-40 motorcycle oil (2 quarts)

Step-by-Step Instructions
-
Prepare the Motorcycle
- Warm up the engine for about 5 minutes to allow the oil to flow better, then power off and secure the bike upright on a stand.
-
Remove the Filler Cap
- Unscrew the oil filler cap/dipstick located on top of the frame. This helps vent the system for smoother oil draining.
-
Drain the Engine Oil
- Position the drain pan beneath the engine.
- Using a 17mm socket, remove the engine sump drain bolt and washer. Allow the old oil to drain fully.
- Inspect the washer for wear or damage. Replace if necessary.
- Reinstall the engine drain bolt and torque to 15 ft-lb.
-
Drain the Frame Oil
- Relocate the drain pan under the frame's lower section.
- Use the 12mm socket to remove the frame drain bolt and washer. Once again, let oil drain completely.
- Check the washer condition and replace if needed. Reinstall the bolt, torquing it to spec.
-
Replace the Oil Filter
- With the 8mm socket, remove the three bolts holding the oil filter cover on the right side of the engine.
- Carefully remove the cover and replace the old filter with a new one. Double-check and replace the cover O-ring if it's damaged.
- Reinstall the cover and bolts; tighten them securely but do not over-torque (hand-tight is adequate).
-
Add New Oil
- Place a funnel in the oil filler opening atop the frame.
- Pour 1.8 liters (about 1.9 quarts) of 10W-40 motorcycle oil if changing both oil and filter. Use 1.7 liters (about 1.8 quarts) if only changing oil without a filter swap.
Note: Exact capacity can vary slightly; always check the dipstick after filling. - Reinstall the oil filler cap and dipstick.
-
Start and Check
- Start the engine and let it idle for 5 minutes. Inspect for leaks around the drain plugs and filter cover.
- Shut off the engine and let it sit for a minute.
- Use the dipstick to confirm the oil level is within the recommended range; top off if needed.
-
Dispose of Used Oil Properly
- Pour used oil into a sealed container and bring it to a recycling center or approved disposal site.
