    Harley Sportster Spark Plugs Replacement

    Bob teaches you how to service the spark plugs on your Harley’s engine. Although you can clean and service your old spark plugs, Bob recommends just buying new ones because they are fairly inexpensive. You should purchase gapped, Harley-only spark plugs which usually come with a gap of 38-43,000th of an inch. After applying some anti-seize to the threads of the new plugs, you can thread them into the cylinder by hand and tighten them with a torque wrench and you’ll be good to go.
