Ironhead sportsters need to be properly maintained and heave there oil changed regularly, this article will explain how to change the oil in an ironhead sportster.

Step 1

Start your ironhead sportster and let it warm up to its normal operating temperature.

Step 2

Next you want to remove the cap on the oil tank, then remove the drain plug on the bottom of the oil tank and drain it . On ironhead sportsters there is no need to remove the drain plug on the bottom of the engine, they are known to strip and are better left alone.

Step 3

Now replace the drain plug on the oil tank and fill with a quality 50 weight oil until it reads on the dipstick. Replace the cap and take your ironhead sportster for a ride !

Ironhead sportsters did not come with oil filters but there are plenty of aftermarket inline filters available, i would suggest getting one to ensure no debris get into your oil.


  • Be sure to check the drain plug after you ride to be sure it hasn't come loose, old ironhead sportsters are famous for vibrating themselves apart.


  • Be sure to dispose of used oil properly.
