Shop parts for a 2017 Honda CRF250L Dirt Bike.

An oil change is one of the most critical maintenance tasks you can perform on your 2017 Honda CRF250L. Regular oil changes ensure your dirt bike runs smoothly, prolongs engine life, and keeps internal components protected against excessive wear and contaminants. Performing this job yourself gives you the confidence to know it’s done right and helps you connect with your bike. Below are step-by-step instructions, tool recommendations, and important model-specific tips to make your oil change easy and effective.

Tools & Supplies Needed

  • Accordion/Oil catch pan (sized for at least 2 quarts)
  • 8mm and 12mm sockets
  • Socket wrench
  • Torque wrench (reads to at least 10 ft-lbs)
  • Funnel
  • Rubber gloves
  • Rags or paper towels
  • Contact or brake cleaner spray (for cleanup)
  • Replacement oil filter (Honda OEM or equivalent)
  • New oil filter gasket (O-ring)
  • New crush washer (for drain bolt)
  • Fresh engine oil (Honda recommends about 1.5L of 10W-30; check manual for climate-specific options)

Step-by-Step Instructions

  1. Preparation
    • Start your bike and let it idle for 3–5 minutes to warm the oil—this helps with complete draining and removes more contaminants from the engine.
    • Shut off the engine. Make sure the bike is securely on a level surface or use a center stand for added stability.
    • If you have a skid plate, remove it for easier access to the drain bolt and oil filter cover.
  2. Drain Old Oil
    • Clean the area around the oil filler cap and the drain bolt with a rag and contact cleaner to prevent debris from falling into the engine.
    • Remove the oil filler cap (top right of the engine) to allow oil to drain more quickly.
    • Position your oil catch pan beneath the drain bolt. Using a 12mm socket, remove the drain bolt and old crush washer.
    • Let the oil fully drain—it may take several minutes and will come out hot, so use caution.
  3. Remove and Replace the Oil Filter
    • Using an 8mm socket, remove the bolts securing the oil filter cover (right side of engine).
    • Carefully remove the cover. Some oil will likely spill at this stage.
    • Remove the old filter and its gasket (O-ring). Take care to note the orientation—flat side usually faces in.
    • Clean the filter cover, gasket seating surface, and install a new O-ring if supplied.
    • Install the new filter in the correct orientation. Reinstall the cover and torque the bolts evenly to 9 ft-lbs.
  4. Install Drain Bolt and Add New Oil
    • Wipe the drain hole clean of any residue.
    • Install a new crush washer on the drain bolt, then reinstall the bolt hand-tight. Tighten with a torque wrench to spec—typically about 18 ft-lbs (consult manual).
    • Add 1.5L (1.6 quarts) of 10W-30 motorcycle oil. Use a funnel to avoid spills.
  5. Final Checks
    • Replace the oil filler cap and clean up any spilled oil.
    • Start the bike and let it idle for 3–5 minutes. Check for any leaks around the oil filter cover and drain plug.
    • Shut the engine off; let the bike rest a minute, then check the oil level with the dipstick. Top off if necessary.
    • Dispose of the used oil and filter properly at your local recycling center or auto parts store.

2017 Honda CRF250L Model-Specific Call-Outs

  • The oil filter orientation is critical: the open side should face out (toward you as you install it), with the flat side in towards the engine. Installing it backward can restrict oil flow and cause engine damage.
  • The recommended oil capacity for an oil and filter change is 1.5 liters. Overfilling can cause excess crankcase pressure and sealing issues, while underfilling can lead to insufficient lubrication.
  • Always use a new oil filter cover gasket (O-ring) and a new crush washer. Reusing them can lead to leaks or improper sealing.
  • Honda recommends the first oil change at 600 miles, and then every 8,000 miles or 12 months thereafter, though extreme conditions may require more frequent service.
  • Consider replacing the OEM drain bolt with a magnetic drain plug for enhanced protection—these collect fine metal particles and give you a "health check" on your engine during each change.

Frequently Asked Questions

  • Q: Do I need special oil?
    Honda recommends 10W-30 motorcycle oil that meets JASO MA standards for wet clutches. Avoid car oils, which may contain friction modifiers that can degrade clutch performance.
  • Q: How do I reset the oil change reminder?
    The 2017 CRF250L does not have an electronic oil change reminder; simply keep a log of your service dates and mileage.
