Changing the oil on your 2004 Honda XR650L is straightforward but includes a few model-specific steps that owners should note. This guide breaks down the task with recommended tools, step-by-step instructions, and important model call-outs for a successful, mess-free oil change that keeps your bike running strong.
Tools and Supplies Needed
- 10 mm wrench or socket (for case bolt)
- 12 mm wrench or socket (for frame drain plug)
- 8 mm or 5 mm Allen key (for oil filter cover, depends on the year)
- Drain pan
- Rags or shop towels
- Long funnel (essential for frame oil fill)
- New oil filter
- Fresh engine oil (high-quality 10W-40 motorcycle oil)
- New sealing washers (recommended, especially for drain bolts)
- Torque wrench (for precise reassembly, optional but recommended)
Recommended Oil – Quantities
- Oil type: High-quality 10W-40 motorcycle oil (brands like Mobil 1, Castrol, Motul recommended)
- Oil quantity: 2.04 US quarts (Honda manual), with many riders using between 2.0 and 2.5 quarts to account for reading variance on the dipstick
- Oil filter: Honda OEM or high-quality aftermarket equivalent
Step-by-Step Oil Change Process
-
Warm Up the Engine
- Run the bike for a few minutes or take a short ride. Warm oil flows better and leaves less residue behind.
-
Secure the Motorcycle
- Park on a level surface and place the bike on its kickstand or a work stand. Turn off the engine and let sit for a couple of minutes for the oil to settle.
-
Locate Drain Plugs and Oil Filter
- The XR650L uses a dry sump system. There are TWO oil drain plugs to remove: one on the bottom of the engine case, and one on the frame under the steering head (down tube drain). The oil filter is housed in a side cover accessed via Allen bolts.
-
Drain the Oil
- Position your drain pan to catch the oil from both drain locations.
- Remove the frame drain bolt (usually 12 mm) first. Oil will flow rapidly.
- Remove the engine case drain bolt (often 10 mm) and let all oil drain completely.
- Be prepared: The majority of oil drains from the frame, but don't skip the lower case bolt as it clears out the remainder.
-
Replace Drain Bolts
- Inspect and replace any sealing washers (crush washers) to prevent future leaks.
- Reinstall both drain bolts after oil drainage and tighten. For best practice, torque frame drain to 40 ft–lbs and case drain to 29 ft–lbs if you have a torque wrench.
-
Replace the Oil Filter
- Remove the oil filter cover with either an 8 mm or 5 mm Allen key (depends on model year and fastener type).
- Pull out the old oil filter and discard. Note orientation before removal: the open end faces out on reinstallation.
- Install a new filter, making sure the O–ring is present and seated properly. Lightly oil the new filter–s seal for best fit.
- Reinstall the filter cover and tighten securely, but do not overtighten to avoid stripping.
-
Add New Oil
- Remove the oil fill cap located at the top of the frame near the gas tank.
- Using your funnel, pour 2.0 quarts initially. Leave the remaining oil aside for final top-off.
-
Start Engine and Circulate Oil
- Start the engine and let it idle for 1 minute, then shut off. This circulates fresh oil and fills the new filter.
- Wait about 2 minutes for oil to settle in the frame, then check level using the dipstick (inserted, not screwed in).
-
Top Off and Final Check
- Add oil until the level is between the marks on the dipstick. Riders typically find total volume between 2.0 – 2.5 quarts is correct depending on residual old oil.
- Check for leaks at both drain bolts and filter cover. Wipe any drips and run the engine again to ensure oil level is stable after warm-up.
2004 Honda XR650L Specific Call-Outs
- Double drain bolts: Many first-timers overlook the frame drain plug—ensure both are removed and reinstalled.
- Frame fill location: Oil is added at the frame's top tube, not directly at the crankcase.
- Dry sump system: The unique oiling layout means oil level checks should always be done with the bike upright and after a warm-up and settling period.
- Oil quantity debate: The Honda manual says 2.04 quarts, but riders often use up to 2.5 quarts for a correct dipstick reading. Do not overfill. Err under, run the engine, then check and top off in small increments.
- Consider a magnetic drain plug upgrade for additional engine protection as suggested by the aftermarket community.
- Replacement of crush washers on drain bolts is good practice each change to prevent slow leaks—these are standard metric sizes and inexpensive to replace.
Final Tips
- Always dispose of used oil and filter responsibly at a proper recycling facility.
- Keep a log of your maintenance with date, mileage, and oil type–amount.
With careful adherence to these model-specific steps, your 2004 Honda XR650L will continue to perform reliably, mile after mile. For OEM Honda parts, maintenance supplies, and more guides, MotoSport.com has you covered.
