Changing the oil regularly is one of the best things you can do to prolong the life of your XS650.


2.02.01 Tools

You will need the following items to change the oil:

  • 2.5 liters of Yamalube or 20W/40 "SE" type motorcycle oil (this is per factory specs, many people have other oils that they like)
  • 1 1/8" (27mm) socket with a long wrench or cheater bar
  • Drip pan to catch the oil (one that holds about 3 liters)
  • Funnel
  • Rags or towel

2.02.02 Measuring the Oil Level

1. Let the engine warm up for several minutes and put the bike up on the center stand.

2. Turn the engine off and wait a few minutes for the oil to settle.

3. Check the oil level by looking through the window on the right side crankcase cover, or by pulling the dipstick.

2.02.03 Remove the Drain Plugs


The drain plugs can be difficult to remove. Here are some options:

1. Warm up the bike to full operating temp, then shut off engine and remove plug using a 1 1/8" (27mm) socket

2. Rap on the drain plug 10 times with the flat side of a 1 lb ballpeen hammer

The drain plug has a magnet on the end of it that collects debris from the oil. When you remove a drain plug, always be sure to clean the gunk off the end before screwing it back in. Make sure you replace the copper crush gasket also.

To make the plugs easier to remove, coat the threads in anti-seize and torque to spec (30.5 ft-lb). Do not overtighten.

2.02.04 Change the Oil

  • Make sure to remove both the oil drain plug and the sump drain plug. Let the oil drain for 10-15 minutes.
  • After the oil has been drained from the bike, check the condition of the oil filter and sump filter for debris, and clean with solvent. See article 2.03._Oil_Filter for more information on how this is done.
  • Replace the drain plugs and crush gaskets. Make sure that you don't overtighten them (torque to 30.5 ft-lbs)
  • Remove the oil filler cap/dipstick from the top of the right side case. Insert a funnel into the hole and pour 2.5 liters of new oil into the case. Screw the oil filler cap back on.

2.02.05 Tricks to removing oil plug

Tricks to removing the XS650 oil plug

1. Run bike until it is good and hot

2. Put bike on center stand

3. Get large breaker bar and a hefty 6 point socket

4. Use small bottle jack to hold socket and breaker bar in place

5. Get a 5 foot piece of pipe to fit over the breaker bar

6. Have some one sit on the bike

7. Remember righty tight lefty loosey.

8. Reinstall drain plug with antiseize

9. Don’t try to crush the copper gasket

You can anneal the old copper gasket and use it over several times. Simply hang the copper gasket on a piece of wire, heat to cherry-red with a Bernz torch (or oxy-acetylene set to a yellow flame 'cos the blue flame will melt it) Drop into cold water. (Fred650)
