The Kawasaki KLX140R L is a versatile bike that requires routine maintenance to ensure optimal performance. In this guide, we will walk you through the process of changing the oil in your 2017 Kawasaki KLX140R L. ### Tools and Supplies Needed To accomplish this task, you will need the following tools and supplies:
  • Ratchet and extension
  • 8mm and 17mm sockets
  • Drain pan
  • Torque wrench
  • Oil filter (Part number specific to your model)
  • Motorcycle oil (10W-40 recommended for most models; approximately 1.22 quarts for the KLX140L)
### Step-by-Step Instructions 1. Warm Up the Engine–Run the engine for about a minute to warm the oil, making it easier to drain. 2. Remove the Dipstick–Pull out the dipstick to vent the crankcase. This helps the oil drain more smoothly. 3. Position the Drain Pan–Place a drain pan under the engine to catch the old oil. 4. Remove the Drain Bolt–Use a 17mm socket to remove the drain bolt located on the lower left side of the crankcase. Be prepared for the oil to start draining out. Remove the crush washer along with the bolt. 5. Allow the Oil to Drain Completely–Let the oil drain completely into the pan. This may take several minutes. 6. Replace the Drain Bolt and Crush Washer–Once the oil has stopped dripping, replace the drain bolt and crush washer. Tighten the bolt to the specified torque setting. 7. Remove the Old Oil Filter–Use a filter wrench to remove the old oil filter. Be careful not to spill any remaining oil. 8. Install the New Oil Filter–Place a new oil filter on the engine and hand tighten it. 9. Refill the Oil–Fill the engine with fresh oil. The recommended oil capacity for the KLX140L is approximately 1.22 quarts. 10. Check the Oil Level–Insert the dipstick into the crankcase without screwing it in, pull it out, and wipe it clean. Insert it back into the crankcase and screw it all the way in. Check the oil level to ensure it is in the middle of the cross-hatch markings. 11. Start the Engine and Recheck–Start the engine and let it run for a few minutes. This will circulate oil into the new filter. Turn off the engine and recheck the oil level. If necessary, add more oil to bring it to the correct level. ### Specific Call-Outs for the 2017 Kawasaki KLX140R L - Oil Capacity—While the KLX140L has a capacity of about 1.22 quarts, it is important to consult your specific model's manual for exact specifications. The KLX140R models may have slightly different recommendations. - Dipstick Screw-in Method—Unlike some other bikes, the Kawasaki service manual advises screwing the dipstick all the way in while the bike is perfectly straight up and down to accurately check the oil level. - Oil Type—Use 10W-40 motorcycle oil for optimal performance across various temperatures. By following these steps and considering the specific call-outs for your model, you can ensure that your 2017 Kawasaki KLX140R L is well-maintained and ready for your next ride.
