Tools and Supplies Needed

  • 12mm socket or wrench (for drain bolt)
  • Drain pan/bucket (to catch old oil)
  • Funnel
  • Clean shop rags
  • Measuring cup (for refill accuracy)
  • Torque wrench (recommended for re-tightening bolts)

Oil Quantity and Specs for 2007 Suzuki RM85L

  • Use 550 ml (1.2 US pt/1.0 Imp pt) of transmission oil
  • Tightening torque for drain plug: 23 N·m (16.5 lb-ft)
  • Tightening torque for oil level screw: 5.5 N·m (4.0 lb-ft)

Step-by-Step Instructions

  1. Warm up the engine
    • Start your RM85L and let it run for 5–10 minutes. This warms the oil for better drainage and helps suspend debris in the fluid for removal.
  2. Place the bike securely
    • Put your bike on a level surface. Hold or secure the bike vertically, not tilted, to ensure all oil drains properly.
  3. Prepare to drain the oil
    • Locate the oil drain plug on the bottom of the engine case.
    • Position your drain pan directly underneath the plug to catch all of the old oil.
  4. Remove the drain plug
    • Using your 12mm socket or wrench, carefully loosen and remove the drain plug.
    • Let all the old oil drain out completely. This may take a few minutes; wiggle the bike gently if needed to help clear all the fluid.
  5. Inspect and clean
    • Check the drain plug for metal shavings or excessive debris—this could indicate internal wear.
    • Clean the drain plug and its threads with a shop rag.
    • Check and replace the drain plug washer or o-ring if worn to prevent leaks.
  6. Reinstall drain plug
    • Thread the drain plug back in by hand to avoid cross-threading. Then use your torque wrench to tighten it to 23 N·m (16.5 lb-ft) .
  7. Add fresh oil
    • Remove the transmission oil filler cap (on the clutch side).
    • With a funnel, pour in 550 ml of the specified oil . Use a measuring cup for accuracy.
    • Clean up any spills.
    • Refit and snug the filler cap. Inspect the cap's o-ring and replace if cracked or missing.
  8. Verify oil level
    • Locate the oil level screw on the engine case.
    • With the bike vertical, remove the oil level screw—oil should gently drain from the hole. If not, add small amounts of oil, refit the screw, and check again until oil escapes from the hole .
    • Reinstall and tighten the oil level screw to 5.5 N·m (4.0 lb-ft).
  9. Run and re-check
    • Start the engine and let it run a few minutes to circulate the new oil.
    • Shut it down, wait 5 minutes, and check again at the oil level screw for proper level .
  10. Final inspection and clean up
    • Wipe off any oil drips and check around the drain and fill areas for leaks.
    • Properly dispose of the old oil per local regulations.

2007 Suzuki RM85L: Model-Specific Tips and Call-Outs

  • Oil Capacity Is Critical: Overfilling or underfilling can harm performance or damage the gearbox. Always measure exactly 550ml during an oil change .
  • Thread Caution: The drain plug threads on the small-bore RM85L are delicate—avoid overtightening, always use a torque wrench, and check the washer condition to prevent stripping or leaking .
  • O-Rings/Seals: The oil filler and drain plugs have o-rings; inspect these every oil change. A cracked or missing o-ring will cause leaks.
  • Warm Oil Drains Best: Do not attempt to drain old oil from a cold engine; it may leave contaminants behind .
  • Always Use JASO MA Oil: For proper clutch operation and transmission longevity, only use oil meeting JASO MA (or MA1, MA2) standards .

Routine Maintenance Frequency

  • For racing or frequent riding, change oil every 5–10 hours of ride time.
  • For lighter usage, change oil at least once per month or after every few rides.

By following these steps and tips, you'll ensure your Suzuki RM85L's longevity and peak performance on any terrain. For all your parts and accessory needs, trust MotoSport.com.
