To replace the spark plugs on a Harley Davidson Sportster, disconnect the coils connected to them: these are located on the left side of the bike, just below the fuel tank. Once all the coils are disconnected, you can remove the spark plugs from their housing using an 8 mm socket wrench. The new spark plugs can then be inserted into their housings and connected to the respective coils. After installing the new spark plugs, turn the key to check that the engine starts.
