Changing the Oil on a Kawasaki KFX450R
Step 1. Warm up and circulate the oil by running the engine for a minute or two.
Step 2. Remove the fill cap, which is located on the crankcase cover.
NOTE: Steps 1 and 2 make draining the engine oil easier.
Step 3. Drain the old oil by removing the drain bolt with a 17mm socket. The drain bolt is located underneath the unit, and also has a crush washer.
Step 4. Use a number 6 Allen to remove the bolts securing the oil filter cover. The cover is located next to the oil fill cap opening from Step 2.
PRO TIP: A small screwdriver can be used to pry the cover off once you remove the bolts.
Step 5. Remove the old oil filter, wipe the old oil from inside the oil filter casing, and install the new oil filter.
NOTE: The rubber grommet on the filter is facing outward. This is important to remember, since the filter is directional.
Step 6. Inspect the O-ring inside the filter cover, and replace it with a new one if it's worn out. Otherwise, reinstall it.
NOTE: These bolts need to be snug, but don’t overtighten them.
Step 7. Replace the drain plug and its crush washer. Use a torque wrench to tighten it to 11 foot-pounds.
Step 8. Fill the engine with 1.3 quarts of 10W-40 oil.
Step 9. Replace the fill cap, then run the engine for a couple of minutes to circulate the oil. Next, check the sight glass to confirm that you have the proper amount of oil in the engine and you're done.
