Shop parts for a 1987 Suzuki DR200 Dirt Bike.

Changing the oil on your 1987 Suzuki DR200 is a foundational maintenance task that will keep your bike running smoothly and prolong its engine life. The DR200 series, including the 1987 model, features a straightforward oil change process, sharing its engine and transmission oil, making for a simple, quick job ideal even for beginning wrenchers. Below is a MotoSport.com proprietary guide tailored for the 1987 DR200, including specific call-outs, tips, and essential details exclusive to this bike.

Tools and Supplies Needed

  • Motorcycle oil (SAE 10W-40, motorcycle-specific for wet-clutch systems)
  • Oil filter (OEM part or equivalent, e.g., K&N KN132)
  • 17mm wrench or socket (for the oil drain bolt)
  • 10mm socket or wrench (for oil filter cover bolts)
  • Oil catch pan
  • Funnel
  • Clean rag (for cleanup and spills)
  • New drain bolt crush washer (recommended)
  • Gloves (optional but keeps hands clean)

1987 Suzuki DR200-Specific Call-Outs

  • The engine and transmission share the same oil; you only need to replace one oil supply.
  • The bike uses approximately 1 quart of oil – do not overfill.
  • Oil temperature: Always warm up the engine for 3–5 minutes before draining for the best results; this suspends contaminants and speeds draining.
  • The oil filter cover has a rubber O-ring and an internal spring. Be careful not to lose or damage these parts.
  • Proper oil for wet clutch use is essential; do not use automotive oil.
  • Sight glass: The 1987 DR200 uses a clear window to check oil level; fill oil until the level sits between the "Full" and "Low" marks with the bike on level ground and blue l upright.

Step-by-Step Oil Change Instructions

  1. Warm up the bike:
    • Start the engine and run it for about five minutes. This helps the oil flow out more thoroughly by suspending contaminants and lowering viscosity.
  2. Place the bike upright on a level surface:
    • Shut off the engine. Place the DR200 on a center stand or have someone help you hold it vertical—never on the side stand when checking or refilling oil.
  3. Remove the oil fill cap:
    • Loosen (but do not remove) the oil fill cap; this prevents a vacuum and helps the oil flow out smoothly.
  4. Drain the old oil:
    • Locate the oil drain bolt underneath the engine (center towards the bottom of the crankcase). Use a 17mm wrench to loosen and remove the bolt carefully—oil will begin to flow quickly into your pan.
    • Do not lose the crush washer on the drain bolt; replace it if it's worn to prevent leaks.
    • Allow the oil to drain completely (5–10 minutes).
  5. Remove and replace the oil filter:
    • Locate the filter cover on the right side of the engine. Remove the three 10mm bolts holding the cover in place.
    • Carefully remove the cover. Watch for the spring and O-ring—note the order and orientation for reassembly.
    • Remove the old filter and check its orientation (open/closed end direction; for most DR200s, the open end faces outward).
    • If the O-ring is damaged, replace it. Clean the mating surfaces.
    • Install the new oil filter in the same orientation. Refit the spring and cover, then tighten the bolts evenly and securely, but do not overtighten to avoid warping the cover.
  6. Reinstall and tighten the drain bolt:
    • Clean the drain bolt and add a new crush washer if possible.
    • Tighten the bolt to factory spec (typically 18 ft-lb or 25 Nm; check your manual if unsure).
  7. Add fresh oil:
    • Use a funnel and pour in about 1 quart (approx. 950 mL) of motorcycle-specific 10W-40 oil.
    • Let the bike sit for a minute, then check the level in the sight glass.
    • The proper oil level is between the "Full" and "Low" lines with the bike upright and on level ground.
    • Add small amounts if needed to top off.
  8. Final steps:
    • Reinstall the oil fill cap and wipe any spilled oil from the bike.
    • Start the engine and let it idle for a minute; check for leaks at the drain bolt and filter cover.
    • Turn off the engine, wait a minute, then check the sight glass again and top off if needed.

MotoSport Pro Tips For the 1987 DR200

  • Dispose of your old oil and filter properly: Most auto parts stores accept used oil for recycling.
  • Always use the correct oil filter: A poor fit or wrong filter can cause catastrophic engine damage.
  • Inspect O-rings and seals every oil change, especially on older bikes where rubber may be degraded.
  • Do not overtighten any bolts—stripped threads on the DR200's aluminum cases are a real risk.
  • Inspect the old oil for metal particles, which could indicate excessive engine wear.

Why Regular Oil Changes Matter

Changing the oil every 1,000–2,000 miles, or after extended trail or competition riding, is one of the best ways to maintain your 1987 Suzuki DR200's reliability and performance. For more expert dirt bike maintenance guidance and OEM-quality parts, shop at MotoSport.com.
