Step-by-Step: How to Change the Transmission Oil
-
Warm up the motorcycle.
Start the JR50 and let it run for a few minutes to warm the engine. Warm oil drains more completely. -
Stabilize the bike.
Place the bike on level ground. The side stand is acceptable, but for a better oil drain you may hold the motorcycle vertically during draining. -
Remove the oil filler cap.
This allows air into the case and speeds up the draining process. -
Locate and remove the drain plug.
Place the drain pan under the engine. Unscrew the drain plug at the bottom of the engine. Let the old oil flow into the pan. -
Allow oil to drain completely.
Gently tilt the bike upright to ensure all oil drains out. Clean the drain plug and its gasket while you wait. -
Reinstall the drain plug.
Screw it back in by hand and snug it with your wrench. Avoid over-tightening, which can strip the threads. -
Remove the oil level screw.
The JR50 uses an oil level inspection screw to indicate when the correct volume has been added. -
Add new oil.
Pour new oil into the filler hole, using a funnel if needed, until oil starts to seep out of the oil level screw hole with the bike upright. -
Reinstall the oil level screw and filler cap.
Once oil reaches the correct level, replace the oil level screw securely, then reinstall and snug the filler cap. -
Clean up.
Wipe any oil drips, dispose of or recycle old oil responsibly, and check for leaks around the drain plug and screws.

- Never use gasoline as a cleaning solvent during the job, and avoid skin contact with used oil to reduce health risks.
- Dispose of used oil and materials according to local regulations to protect the environment.
Warnings & Maintenance Reminders
- Let the engine and exhaust cool before you start to prevent burns.
