Step-by-Step Oil Change Instructions
-
Warm Up the Engine
- Start and run the XT350 for a few minutes to warm the oil. This helps it flow out more easily when draining. Do not overheat—just bring it to normal operating temperature.
-
Prepare the Bike
- Turn off the engine and place the bike on a level surface.
- If possible, use a stand to keep the bike upright for level draining.
-
Remove the Oil Filler Cap
- Locate the oil filler cap on the top of the right side crankcase and remove it. This allows air in so oil drains faster.
-
Place the Oil Drain Pan
- Position the pan directly under the drain bolt beneath the engine.
-
Remove the Drain Bolt and Air Bleed Screw
- With your socket wrench, carefully remove the oil drain bolt and the nearby air bleed screw. Let the oil drain completely into the pan.
- Inspect the drain bolt's gasket—replace if damaged.
-
Remove the Oil Filter and Cover
- On the right side of the engine, remove the three oil filter cover screws. Start with the lowest screw to help the filter housing drain without mess.
- Carefully remove the oil filter cover and the old filter.
- Inspect and clean the filter cavity and the O-rings. Replace the O-rings if they're damaged or excessively worn.
-
Clean or Replace the Oil Filter
- If reusing the filter element, clean it with solvent and air dry. Replace the filter if it appears excessively dirty or damaged.
-
Reinstall the Filter and Cover
- Insert the clean or new filter into its cavity.
- Ensure the O-ring is properly seated to avoid leaks.
- Reattach the filter cover and tighten the screws to 10 Nm (7.2 ft-lb).
-
Replace the Drain Bolt and Air Bleed Screw
- Reinstall the drain bolt and torque it to 43 Nm (31 ft-lb).
- Reinstall the air bleed screw and ensure it's snug.
-
Add New Engine Oil
- With a clean funnel, pour in 1.3–1.4 liters of the recommended oil (see above for capacity). Avoid overfilling.
-
Check Oil Level
- Let the oil settle for a few minutes. Check the oil through the window on the right crankcase. The level should be between the minimum and maximum marks.
- Top up if necessary. Replace the oil filler cap once satisfied.
-
Start Engine and Inspect
- Start the engine and let it idle for a couple of minutes; check for leaks around the filter and drain bolt.
- Stop the engine and recheck oil level, topping up as needed.
Pro Tips for 1993 XT350 Oil Changes
- Always use the correct oil type and do not mix oil brands/weights if unnecessary.
- Allow the oil to drain completely for the best results—this may take several minutes after the flow slows down.
- Dispose of the old oil and filter responsibly at a proper recycling facility.
- Check for oil leaks around the oil filter cover, drain bolt, and filler cap after the first ride.
Model-Specific Call-Outs
- The XT350 oil filter cover has three screws, and the lowest one helps drain the cavity—unique compared to many other Yamaha models.
- Tightening to the specified torque is critical for both the drain plug and filter cover on this model to avoid oil leaks or thread damage.
- Always check the condition of the O-rings and gaskets during each oil change, as aging rubber can cause leaks over time.
- Your oil level window is sensitive to bike tilt; always keep the motorcycle upright and level when checking oil level.
