Keeping your 1996 Honda CR250R performing at its peak means regular maintenance, and changing the transmission (gear) oil is a vital service. This step-by-step guide is proprietary to MotoSport.com and details everything you need: tools required, step-by-step instructions, and model-specific advice for your 1996 CR250R.

Tools & Supplies Needed

  • 17mm socket (for drain bolt)
  • 10mm socket or wrench (for check and fill bolts)
  • Drain pan
  • Rags or shop towels
  • Gloves (to protect your hands from used oil)
  • Funnel
  • Measuring cup (such as a Ratio Rite, for accurate oil measurement)
  • Maxima MTL 10W-40 transmission oil or equivalent oil (use 650cc or specified amount)
  • Replacement copper crush washer for drain bolt (if current is worn or deformed)

Special Notes for the 1996 Honda CR250R

  • This is a 2-stroke bike; only the transmission/gearbox has serviceable oil. The engine itself uses premixed two-stroke fuel, not engine oil.
  • Oil change interval: At least every 3 races or 7.5 hours of running to ensure consistent clutch and transmission life.
  • Always warm up the engine before changing oil. Warm oil flows better and carries more contaminants out with it.
  • The oil capacity is about 650cc. Never overfill or underfill—the correct level is crucial.
  • The oil level check bolt is located just to the right of the clutch cover, identified by a copper washer.

How to Change Transmission Oil

  • Start and warm up the engine for 2–3 minutes, then shut it off. This helps suspend debris in the oil for a more complete drain.
  • Remove the oil fill cap on top of the right crankcase cover.
  • Place a drain pan under the bike.
  • Remove the transmission drain bolt (17mm socket, bottom of right side engine case—consult your manual to identify). Watch for the copper crush washer; replace if damaged.
  • Allow oil to fully drain. Wait until oil slows to mere drips.
  • Inspect and clean the drain bolt. If it has a magnet, check and clean any metal shavings.
  • Reinstall the drain bolt with the copper washer. Torque to 6–9 ft-lb (8–12 N-m). Do not overtighten; the case is aluminum and threads can strip easily.
  • Fill with fresh transmission oil:
    • Measure out 650cc of 10W-40 gear/transmission oil (like Maxima MTL).
    • Use a funnel to avoid spills; pour the oil into the fill hole.
    • Replace the fill cap.
  • Check the oil level:
    • Start the engine and let it idle a minute. Shut off.
    • Remove the oil check bolt (side of clutch cover, 10mm, with copper washer).
    • Oil should just barely drip out—this is the correct level. If oil doesn't drip, add small amounts until it does.
    • Reinstall check bolt, tightening to 6–9 ft-lb (8–12 N-m).
  • Final steps:
    • Wipe off any oil spills.
    • Dispose of the used oil at a recycling center.
    • Check the area for leaks after a short ride.

1996 CR250R Model-Specific Tips

  • Drain bolt threads are soft aluminum—be careful not to cross-thread or over-tighten.
  • If the copper washer is missing or deformed, replace to prevent leaks.
  • This model has a separate water drain bolt for the coolant—double-check you are removing the correct drain bolt for oil, not coolant (oil plug has a copper washer and sits just below and behind the clutch cover).
  • If unsure, reference the Honda service manual for bolt locations before beginning. Mistaking the water drain for the oil drain is a common error for first-timers.

Safety and Environmental Precautions

  • Used transmission oil is hazardous; avoid skin contact and wash thoroughly if exposed.
  • Never dispose of oil on the ground or in the trash—use a recycling center.

MotoSport Pro Tip

  • Keep a maintenance log including date, hours, and oil brand/weight. Frequent changes can prolong the lifespan of your CR250R’s clutch and transmission.
  • If you ride in extreme conditions (sand, mud, aggressive clutch use), consider changing oil more often.

By following this guide, you’ll keep your 1996 Honda CR250R transmission running smooth and extend the life of its critical components. For all your maintenance needs and top-quality parts and lubricants, MotoSport.com has you covered.
