How to Change the Oil in a Suzuki M109R

You should change the oil on your motorcycle every 1,000 miles to ensure that the engine continues to run properly. This procedure is relatively straightforward on many bikes, due to the mechanical layout and clearance of the bike off the ground. For the Suzuki M109R, replacing the oil is complicated by the bike's low clearance and the fact that the engine needs to run for a bit before you can get a proper oil reading and adequate oil drainage. But with the proper tools and guidance, you should be able to change the oil in your Suzuki M109R with relative ease.

  1. 1

    Turn on your M109R and let it run for at least 15 minutes. Turn the bike off and let it sit for no more than three minutes. The oil must be warm to get a proper oil reading and let the oil drain completely.

  2. 2

    Drive or wheel your bike up onto a set of bike stands. Because of the low clearance of the M109's oil pan, it is impossible to access the oil pan's drain plug and place a drain tray underneath it without the increased clearance provided by the bike stand.

  3. 3

    Position an oil drainage tray underneath the bike's drain plugs.

  4. 4

    Crack and remove the oil pan's drain plugs with a ratchet wrench. The drain plugs look like a small bolts screwed into a large flat container at the bottom of your bike, between the front and rear tires. Oil will pour from the pan's plug holes as soon as the plug bolts are removed. You may need to adjust the drainage tray to ensure that you are catching all of the oil.

  5. 5

    Replace the drain plug bolts when the oil has completely drained from your M109R.

  6. 6

    Remove the oil filler cap and add clean oil to the oil pan. Your M109R requires 3.4 litres of oil if you are replacing just the oil, and 3.6 litres if you are replacing the oil and the oil filter. Reattach the filler cap.

Tips and warnings

  • Remove your M109's filler cap and dipstick to speed up the drainage.
