Shop parts for a 2019 Honda CRF50F Dirt Bike.

Changing the oil in your 2019 Honda CRF50F is a vital maintenance step that keeps your dirt bike running optimally and ensures a long life for its engine. Follow this thorough guide, proprietary to MotoSport.com, for a successful and clean oil change every time.

Tools and Materials Needed

• 17mm socket or wrench (for drain bolt)
• Socket wrench
• Oil drain pan
• Clean funnel
• Measuring cup (metric, for accurate oil amount)
• New engine oil (Honda recommends 10W-30 or as specified in your owner's manual)
• New sealing washer (for drain bolt)
• Clean shop rags
• Gloves
• Magnetic drain plug (optional, but recommended for catching metal debris in youth bikes)

2019 Honda CRF50F Oil Change Specifics

• Recommended oil quantity: 0.6 US qt (600 mL)
• Drain bolt torque specification: 18 lbf·ft (24 N·m, 2.5 kgf·m)
• Check oil level with bike upright and dipstick resting on the threads–do not screw in the dipstick when measuring.
• Do NOT remove the cam chain tensioner pushrod bolt—it’s near the oil drain and is sometimes confused for the drain bolt.

Step-by-Step Instructions

• 1. Warm Up the Engine
  Start the bike and let it idle for 3-5 minutes. Warm oil drains more readily and thoroughly. Be careful: the engine and exhaust will get hot. Turn the bike off and let it rest for 2-3 minutes to allow the oil to settle.
  Tip: Avoid burns by handling only cool parts and wearing gloves.
• 2. Secure the Dirt Bike
  Place the CRF50F on a firm, level surface. Use a bike stand if you have one. This keeps the bike stable throughout the process and ensures proper oil drainage.
  Safety call-out: An unstable bike can tip over during draining or refilling.
• 3. Remove the Dipstick/Filler Cap
  Unscrew and set aside the oil fill cap/dipstick. This allows air in and old oil out.
  
• 4. Drain the Old Oil
  Position your drain pan beneath the engine. Locate the oil drain bolt (right side of the crankcase, 17mm head).
  Remove the bolt carefully with your socket wrench, and allow the oil to drain fully.
  Honda caution: Do NOT remove the cam chain tensioner pushrod bolt. It’s near the drain bolt but serves a very different function. If removed, consult your dealer.
  Once the main oil flow has stopped, gently tilt the bike from side to side to drain out the last remnants.
  For 2019 model owners: First oil changes may show some metal shavings in the oil–this is normal as the engine breaks in, but it’s a good time to install a magnetic drain plug to catch debris going forward.
• 5. Inspect and Replace the Sealing Washer
  Remove the old sealing washer from the drain bolt and replace it with a new one. This is crucial for preventing leaks.
• 6. Reinstall the Drain Bolt
  Screw in the drain bolt by hand, then tighten it to 18 lbf·ft (24 N·m, 2.5 kgf·m) using your torque wrench. Do not overtighten.
• 7. Add New Oil
  Insert your funnel into the oil fill hole and pour in 600 milliliters (0.6 US qt) of fresh oil. You may find it helps to pour a bit less, check the level, and top off as needed.
• 8. Replace the Dipstick/Filler Cap
  Install the dipstick/oil cap and tighten securely.
• 9. Check Oil Level
  Start the engine and let it run for 3-5 minutes to circulate the new oil. Turn off the bike and allow it to sit for 2-3 minutes again.
  With the bike upright on level ground, remove the dipstick and wipe clean. Reinsert the dipstick but do not screw it in. Remove to check level. The oil should be between the two marks. If below the upper mark, add more oil–do not overfill.
• 10. Final Checks and Clean Up
  Inspect around the drain bolt and bottom of the engine for any signs of leaks. Wipe down any residual oil and safely dispose of your used oil at an appropriate recycling center or auto parts store.

Special Tips & Call-outs for the 2019 Honda CRF50F

• New CRF50F: If this is the bike’s first oil change, expect a small amount of metal shavings in the oil–normal during initial break-in. Adding a magnetic drain plug at this stage can help keep your engine even cleaner during subsequent rides.
• Oil Capacity Variance: If not all old oil drains out, you may need slightly less than 600 mL. Always go by the dipstick reading and bike upright position.
• Be Careful Not to Overfill: Overfilling with oil can cause foaming and engine problems. Stay within the upper and lower dipstick marks.
• Dispose of Oil Properly: Old engine oil is harmful to the environment and must be disposed of legally and safely.

Frequently Asked Oil Change Questions for the Honda CRF50F

• How often should I change the oil? Honda recommends following a frequent oil change schedule for youth dirt bikes–often every 10-15 hours of riding—or after every few long rides.
• Can I use automotive oil? No. Always use motorcycle-specific oil meeting API SG or higher, JASO MA specs for wet clutch compatibility.
• Where can I find oil and washers? MotoSport.com offers high-quality oils and CRF50F oil change kits for convenience and peace of mind.
