Performing regular oil changes on your GS500F is the best way to prolong the engine life of your motorcycle. An oil change requires few tools and very little time. Completing this task on your own will save you money and time over visiting a dealer or mechanic. Change the oil regularly, at least every 4,000 miles as recommended by the manufacturer.
Place your GS500F on its centre stand. Spread newspapers beneath the engine area and place an oil pan or other container under the oil drain plug.
Loosen the bolts on the oil filter cover, just enough to break the seal, but not far enough that oil begins to leak out. Loosen the oil drain plug below the engine, just enough to break the seal but not enough that oil leaks out. You want to loosen these parts so that they are easy to remove once the engine is hot.
Start the engine and let the bike idle for five minutes. Turn the engine off and let it cool for two or three minutes. If you just finished riding your bike you can skip this part since the engine will already be warm.
Remove the dipstick cover on the engine and leave it off until you are finished.
Remove the oil drain plug completely and let the oil drain into the pan.
Remove the oil filter cover completely, starting with the nut located at the bottom of the cover, to allow the oil to flow freely down into the pan.
Remove the oil filter and hold it over the oil pan to allow it to drain completely. Clean the filter with paper towels or replace if overdue. The manufacturer recommends changing the filter at least every other time you change the oil.
Allow the old oil to drain completely. Put the oil filter and cover back into place and bolt the cover back on. Place the drain plug back into the motorcycle and tighten it back into place.
Place a funnel in the crankcase where the dipstick was located and add more oil. Check your owner's manual for the recommendations on the type and amount of oil to use. A GS500F generally needs three quarts of SAE 10W-40 oil, but it can vary depending on the climate.
Replace the dipstick cover and start your motorcycle, allowing it to idle for two to three minutes. Turn it off and check the oil level again, adding more if necessary.
