If you look at the top of the Induction module, you'll see if it is either black ( single looking tube ) or Silver ( Looks like 2 tubes together ) Single tube is Delphi, Silver Dual tube is Magnetti .

SOURCE: How do I change the oil on a 2002 fat boy?

On the fatboy, the oil drain plug should be on the right side, just under the frame, directly below the oil tank. The primary drain is on the left side under the derby cover on the bottom. The tranny drain is on the bottom towards the rear pretty much centered.
And, as our darlin' little miss piglet said, a maual is worth the investment.

SOURCE: how to change oil on 2002 fat boy

The drain plug is a hose that comes down to a sprung clamp on the frame behind the gear box on the right side of your bike. Remove from clamp then undo the screw-ring round the hose to allow the plug in the hose to be removed, take lid off oil tank and turn engine over a coupla times to clear engine oil into drainage tank. Replace plug- etc before refilling with half the oil, turn engine over coupla times then add remaining top up oil. Drainage for your primary oil is at the rear inside near the gasket joint and can be removed with a Hex spanner, taking the large outside cover off your primary with star drive sockets to allow airflow for drainage and then to pour new oil in through after replacing drainage plug in the bottom. Buy a Manual Mate, its worth it eh considering the value of your bike?

SOURCE: fuel gage not working on harley fat boy

The fuel gauge is really two parts. You have a guage and a sending unit. You must have voltage going to the unit as well. On most models, the wires that supply voltage to the gauge run upwards through a small tube in the tank for the bottom of the tank. There is a connector at the bottom of the tank in most cases.

Using a VOM (volt/ohm meter) unplug the connector beneath the tank and check for voltage with the ignition switch on. You should have approx. 12 volts. Once you've finished this test, turn the switch back to the off position.

Next, you will have to check the sending unit. Remove the gauge from it's rubber gasket that holds it in position on the tank. Carefully work the gauge up and out of the rubber sleeve because the wires are very short. Once you have the gauge out, you'll have to check the resistance of the sending unit with the tank nearly full and then again with the tank nearly empty. If the resistance of the sending unit changes, the problem is probably the gauge itself. If the resistance does not change, the problem is more than likely with the sending unit. Check the sending unit for a good ground as well.

The sending unit is held in the tank by five or six small screws. Remove these screws and lift the unit slightly. Do not attempt to remove the sending unit with the fuel tanks full and the bike on the side stand. Fuel will be all the way to the top of the tank and will spill out when you attempt to remove the sending unit. While lifting the unit, turn it working the float arm out of the tank. Be very careful not to bend the float arm. Once you have the unit out of the tank, you can check the unit's resistance again. When you remove the sending unit, always replace the gasket that goes beneath the unit.

Be very careful, you are working with gasoline and expolsive fumes. Do not smoke or have any open flames near.

I put a heavy breather air cleaner on my 02 fat boy its fuel injected. Now around 30 to 40 mph it sputters and backfires.


If it continues to do this, you'll have to take it to the dealer and have the fuel map adjusted.

Good luck

Fuel injection Harley Davidson 02 Fatboy


System is self bleeding. You may have disturbed some debris that has gotten in the fuel injector/s. Try running some fuel injection cleaner through it and see what happens.
