Changing the oil in your 2014 Honda CRF125FB is an essential maintenance step to ensure optimum engine performance and longevity. This guide will walk you through each step, including specific notes on this model. If you're a first-timer or simply want a reminder, read on for a clear, robust process.
Tools and Supplies Needed
- 10W-30 or 10W-40 motorcycle-specific oil (Honda GN4 or equivalent); capacity: 0.9 US qt (0.85 L)
- 17mm socket (deep well or with extension recommended)
- Socket wrench
- Drain pan for used oil
- New sealing washer for the drain bolt
- Funnel (small size to fit the fill hole easily)
- Clean rags or paper towels
- Measuring cup (if your oil container doesn't have markers)
- Owner’s manual (for torque specifications and reference)
Preparation
- Start the engine and let it idle for 3-5 minutes to warm up the oil. This helps the oil drain more easily and thoroughly.
- Turn the engine off and wait 2-3 minutes so oil can settle in the crankcase.
- Park the bike on its side stand, ensuring it’s on a stable, level surface for safe and proper drainage.
Step-by-Step Oil Change Instructions
-
Remove the Oil Fill Cap and Prepare the Drain Pan
- Unscrew and remove the oil fill cap/dipstick on the right side of the engine. This step is key for smooth draining by preventing airlocks.
- Place your drain pan directly under the crankcase, centered on the bike. The skid plate on the CRF125FB has a convenient notch for access to the drain plug.
-
Locate and Remove the Drain Plug
- The oil drain bolt is located on the center bottom of the crankcase, easy to access, and marked out in your owner’s manual.
- Use the 17mm socket and wrench to carefully loosen and remove the drain bolt and its sealing washer.
- Allow all oil to drain into the pan. A warm engine ensures more thorough drainage.
- Check the sealing washer; always replace it to prevent leaks.
-
Reinstall the Drain Bolt
- Once the oil is finished draining, reinstall the drain plug with the new sealing washer. Tighten to 18 lbf·ft (24 N·m, 2.4 kgf·m).
- Wipe up any spilled oil around the drain area for a clean finish.
-
Refill with Fresh Oil
- Insert your funnel into the oil fill hole. Pour in 0.9 US qt (0.85 L) of the recommended oil.
- A slow pour helps prevent overfilling; double-check your measurement if in doubt.
-
Secure the Oil Cap and Check Oil Level
- Install the oil fill cap/dipstick, but for an accurate reading do not screw it in. Simply rest it in the hole, then remove and check. The oil level should be near the top mark on the dipstick.
- Start the engine and let it idle for 3-5 minutes. Shut off and let the bike sit for 2-3 minutes to allow the oil to settle, then check the level again in the same way. Add oil if necessary, being careful not to overfill.
-
Final Checks
- Inspect the area around the drain bolt and oil fill cap for leaks.
- Dispose of your used oil responsibly at an approved recycling facility.
Model-Specific Call-Outs for the 2014 Honda CRF125FB
- This bike does not have a traditional oil filter. There is a small screen strainer inside, but on standard oil change intervals you are not required to service or change a filter.
- Do not over-tighten the drain bolt as the crankcase is aluminum and can strip easily.
- Always replace the sealing washer on the drain bolt to prevent drips.
- Only rest the dipstick on the threads without screwing it in when checking the oil level. Screwing it in gives a false reading and could lead to over- or under-filling the engine.
- The oil fill hole is small, so use a small funnel to prevent spills and make refilling easier.
- The correct oil level should be between the dipstick hash marks. Running the bike slightly low is better than overfilled, as overfilling can cause crankcase pressure issues.
- Stick to regular oil changes; these smaller Honda engines run hotter and work hard, so fresh oil ensures longer life.
Additional Tips
- Keep a maintenance log with dates and quantities used.
- Store your oil in a clean, dry place and keep track of open containers for future use.
- Follow the recommended service intervals in your Honda owner’s manual for best performance and warranty retention.
