Now that you’ve fully serviced your Harley Sportster, you can take the opportunity to check all of the safety features on the bike. Make sure the lights are working properly, the horn makes noise, turn signals are operational, and all grommets are in place. Then you should check the throttle, add oil and fill the tires to the correct level. Once your finished with the service, get out and ride!
*****The service manual states you should follow your negation cable down from battery and remove nut that secures the connector to ground stud on the crankcase boss behind the starter motor assembly. You will need to do the reverse during installation.
In order to service the fuel filter on your Sportster, you’ll need to drain the fuel tank. Bob demonstrates the best way to do this using a MityVac and a gasoline can. Once you follow his instructions and drain the fuel tank filter, cleaning any dirty parts and tightening any loose bolts, you can refill the tank with fuel and your bike should be good to go.
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.
