How to Change the Oil on Kawasaki Bikes

by Contributing Writer; Updated June 12, 2017

The Kawasaki bike is a high-performance all-terrain vehicle--a racing-oriented four-wheeler. The Kawasaki bike liquid-cooled four-stroke engine has a counterbalancer and overhead cams--it's a high-tech piece of machinery that requires ATV oil only for lubrication. Regular motor oil has friction modifiers that can play havoc on the clutch. The brand of oil used isn't important; synthetic oil could be used, as long as it is made specifically for ATVs. The Kawasaki bike uses just over two quarts of oil with a new filter.

 How to Change the Oil in a Vulcan 900

Park the motorcycle on level ground to ensure that the oil drains completely. Place a drain pan beneath the oil pan drain plug, which is on the bottom of the engine.

Use a 17mm wrench to turn the plug counterclockwise to loosen it. Finish unscrewing the plug by hand and remove it from the drain pan. Wait for the oil to stop flowing, then place the bike upright off the kickstand to allow any remaining oil to drain. When finished, replace the drain plug and tighten with the 17mm wrench.

Find the rectifier cover on the front of the engine, just behind the front wheel. It is a flat, square-shaped piece with slots cut into it. Use a 10mm wrench to remove the two bolts that attach the cover to the rectifier, and remove it from the engine. You will now be able to access the rectifier.

Use a 10mm wrench to remove the two bolts that attach the rectifier to its mounting bracket, and rotate it out of the way. It will still be attached to the engine by a wire harness, but it will be out of the way of the oil filter.

Remove the right side bolt that attaches the rectifier mounting bracket to the engine, and loosen the left bolt enough to allow you to rotate the mounting bracket away from the oil filter.

Use an oil filter wrench to loosen the filter, and continue to remove it by hand.

Prepare the new filter by rubbing a few drops of the old oil onto the rubber seal. Screw the new filter onto the fitting, and use the filter wrench to tighten it.

Rotate the rectifier housing back into place, replace the bolt you removed, and tighten the left bolt. Replace the rectifier and insert the two mounting bolts. Replace the rectifier cover and insert the two bolts.

Open the oil filler cap on the top left side of the engine. Insert the funnel and add approximately 3 quarts of oil. Place the bike in an upright position and view the oil level through the sighting window on the left side of the engine. Having an assistant makes this task much easier. Ensure that the oil reaches the level indicated by the two marks on the side of the window. If not, add more oil.

 How to Change the Oil on a 1983 Kawasaki 550

Lift the motorcycle onto its center stand to hold it completely upright and as level as possible. Look under the motor to find the oil drain bolt and the oil filter's housing. The oil filter is held behind a cover near the cross-over tube, between the exhaust pipes. The oil drain bolt is positioned a few inches away from the oil filter, near the junction between the exhaust pipes and the mufflers.

Start the motorcycle while it is on the center stand and let it idle for three minutes. This will warm the motor's oil supply, allowing the oil to drain completely later in the job. Stop the motor after three minutes and let it cool for another five minutes.

Unscrew the oil cap from the right side of the motor by hand. Place your oil pan beneath the oil drain bolt. Unscrew the oil drain bolt with a 17 mm socket and drain the oil into your oil pan.
