Keeping your 1997 Yamaha XT350 running smoothly starts with regular oil changes. This DIY guide, proprietary to MotoSport.com, outlines the process, tool list, and model-specific insights for a successful oil change on your XT350.

Tools and Supplies Needed

  • Socket wrench set (for drain bolt and filter cover screws)
  • Flathead screwdriver (for filter cover)
  • Oil drain pan
  • Replacement oil filter (Yamaha Genuine recommended)
  • Replacement oil (SAE 10W-40 or SAE 20W40, Type SE; refer to manual for temperature-specific recommendations)
  • Gloves
  • Shop rags
  • Torque wrench (for proper tightening)
  • New O-rings (for filter cover, if needed)
  • Funnel

Preparation

  • Warm up the engine for a few minutes. This helps the oil flow more easily when draining. Do not let it get excessively hot.
  • Place the motorcycle on a level surface and secure it upright.
  • Make sure all your tools and replacement parts are within reach before you begin.

Step-by-Step Oil Change Process

  1. Locate the Oil Level Window:
    • The oil level window is at the lower part of the right side crankcase cover.
    • With the bike upright, check oil through this window. The level should sit between the max and min marks after the engine cools for a few minutes.
  2. Drain the Old Oil:
    • Remove the oil filler cap.
    • Place the oil drain pan under the drain bolt (at the bottom of the engine).
    • Loosen and remove the drain bolt using your socket wrench. Oil will begin to drain rapidly.
    • Remove the air bleed screw (if equipped) to assist full draining.
    • Allow several minutes for all old oil to empty.
  3. Remove and Inspect the Oil Filter:
    • The filter cover is held by three screws. Remove the lower screw first for better drainage.
    • Take off the oil filter cover and extract the used oil filter.
    • Inspect and, if required, replace the O-rings on the filter cover to ensure a good seal.
    • Clean the filter cavity with a clean rag.
    • If reusing the filter (not recommended after long intervals), clean thoroughly with solvent and dry.
  4. Install the New Oil Filter:
    • Insert the new filter into the filter housing.
    • Confirm the O-ring(s) are undamaged and in place.
    • Replace the filter cover and tighten all three screws. Tighten to:
    • Filter cover screws: 10 Nm (7.2 ft-lb)
  5. Reinstall the Drain Bolt:
    • Check the gasket on the drain bolt and replace if needed.
    • Tighten the drain bolt to 43 Nm (31 ft-lb)
  6. Refill with New Oil:
    • Use a funnel to add your chosen oil.
    • Oil capacity is 1.3 L (1.14 Imp qt, 1.34 US qt) for a standard change, and 1.4 L (1.23 Imp qt, 1.44 US qt) when replacing the filter. Add just under the full amount first; you can always top up after checking the level.
    • Replace the oil filler cap.
    • Start the engine and run briefly. Check for leaks. Allow oil to settle, then ensure the level sits between max and min marks in the oil window.
  7. Final Checks and Cleaning:
    • Inspect all sealing faces and confirm there are no leaks.
    • Properly dispose of the old oil and filter (do not pour into drains or trash).
    • Make a note of the date and mileage for your maintenance records.

Model-Specific Call-Outs for 1997 Yamaha XT350

  • Oil Window Location: The oil sight glass is on the lower right crankcase cover. Always check the level with the motorcycle upright–tilting gives inaccurate readings.
  • Filter Cover Screws: Remove the lower filter cover screw first to allow thorough draining of the cavity and minimize mess.
  • O-ring Attention: Carefully check O-rings—damaged rings can cause leaks due to the high-pressure lubrication system.
  • Drain Bolt Torque Spec: Ensure you do not overtighten; aluminum threads can strip if exceeded.
  • Recommended Oil Type: For most climates, SAE 10W-40 (Yamalube or equivalent) is standard, but SAE 20W40 is also listed in official guides for warmer conditions.
    Always follow Yamaha's official maintenance schedule for best results and extended engine life.

Helpful Tips

  • Run engine for a few minutes before each change to suspend particulates and aid draining.
  • If you race or ride in extreme conditions, change your oil more frequently to maintain optimal engine health.
  • Inspect the drained oil for metallic flakes or discoloration, which can be early signs of motor wear or internal damage.
  • Be sure to properly seat and torque all bolts according to the service manual; do not overtighten.

Doing your own oil change on a 1997 Yamaha XT350 is a straightforward task when you gather the right tools and follow these steps. This process not only saves you shop fees but also helps you understand your motorcycle better.
