Tools and Materials Needed
- Ratchet
- 8mm, 12mm, and 17mm sockets
- Torque wrench
- Drain pan
- Oil filter (OEM or high-performance equivalent)
- 10W-40 motorcycle oil (2 quarts recommended)
- Funnel
- Gloves and safety glasses
- Rags or shop towels
- Optional: Skid plate removal tools if fitted
Step-by-Step Oil Change Process
-
Warm Up the Engine
- Start the engine and let it idle for 2–3 minutes. This helps the oil flow out more easily during draining.
-
Remove the Oil Filler Cap/Dipstick
- With the engine off, remove the oil filler cap/dipstick. (Located at the top of the frame–this allows air in and helps the oil drain quickly.)
-
Drain the Oil from the Engine
- Place your drain pan under the 17mm drain bolt at the bottom of the crankcase.
- Remove the drain bolt and crush washer, letting old oil fully drain.
- Inspect the washer and replace if worn or damaged.
- Reinstall the bolt and washer once draining has slowed to drips, and torque to 15 ft-lb (20 Nm).
-
Drain the Oil from the Frame
- The DRZ400SM has a dry-sump system with a secondary drain in the lower part of the frame backbone.
- Locate the 12mm drain bolt on the frame, position your pan, and remove the bolt/washer; allow oil to fully drain.
- Clean, inspect, and reinstall this bolt and washer, tightening securely (do not overtighten).
-
Replace the Oil Filter
- Use an 8mm socket to remove the two bolts from the oil filter cover on the right crankcase.
- Carefully remove the old oil filter. Clean the filter cavity and ensure the O-ring is in good condition (replace if needed).
- Install the new filter, making sure it is oriented properly. Replace the cover and torque the bolts evenly (do not overtighten).
-
Add Fresh Oil
- Using a funnel, add fresh 10W-40 motorcycle oil into the filler on top of the frame.
- For filter and oil change: add 1.8 liters (1.9 quarts).
- For oil only (no filter): add 1.7 liters (1.8 quarts).
-
Start the Engine and Circulate Oil
- With everything buttoned up, start the bike and let it idle for about five minutes. Shut it off and wait a few minutes.
-
Check Oil Level
- Insert the dipstick into the filler neck (but do NOT screw it in), then remove to check level. Add oil if needed to bring it within the marked range.
- Important: On the DRZ400SM and similar models, the dipstick should only be rested in the threads when checking oil, never screwed in. This ensures an accurate reading.
-
Inspect for Leaks and Finalize
- Wipe down the bike, reinstall any skid plates, and check for leaks around drain bolts and the filter.
- Dispose of old oil and filter properly at a recycling center.
Model-Specific Notes for the 2014 Suzuki DRZ400SM
- The DRZ400SM oil change procedure is almost identical to other years and DRZ variants (S, E), as Suzuki has not significantly changed the engine since 2000.
- Two drain points: oil from the crankcase and from the frame backbone–be sure to drain both for a full change.
- Watch out for a mesh oil strainer screen inside the frame drain plug. Remove carefully, clean, inspect, and reinstall.
- Always use motorcycle-specific oil–never car oil, as friction modifiers can damage the wet clutch.
- Replace drain bolt washers if they appear worn or flattened. A fresh seal prevents leaks.
Recommended Maintenance Interval
- Initial oil change: at 600 miles (1,000 km).
- Regular interval: every 3,000–3,500 miles (5,000–6,000 km) or at least once per season.
- Change oil more often if riding in dusty, muddy, or heavy off-road conditions.
Final Tips
- Keep a maintenance log to track oil changes and other service.
- Don't overtighten bolts–use a torque wrench for key fasteners as specified above.
- If the bike won’t idle or oil pressure light stays on after refilling, turn off the engine and check for leaks or missing washers.
