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.

Do I need to drain the engine case on my 2002 Fat Boy when changing the oil?


Most people don't bother, because if everything is working right, it'll only have 2-3 tablespoons worth of oil, so it's hardly worth it.

2005 fat boy oil change


Stand the bike upright. Remove the dipstick from the oil tank. Remove the drain plug on the bottom right side of the frame. While the oil is draining, replace the oring on the drain plug. Remove and replace the oil filter, after filling the new filter half full of oil. Replace the drain plug. Put 3 quarts of oil in the oil tank. Replace the dipstick. Start the bike and check for leaks. No leaks, you're done! I use HD Syn 3 synthetic oil in my '04 Fatboy, but you can also use a conventional 20w50, as long as it's made for use in and air cooled motorcycle. Don't use car oil!

Where is the oil plug to drain the oil on a 2005 Fat Boy Harley Davidson


The oil drain hose comes of the lower back side of the oil tank on the right side of the bike. It runs down behind the transmission and comes out just in front of the swingarm down low on the frame. It either dead ends there with a plug in the end or it connects to a crossmember of the frame that runs underneath the transmission. If it connects to this crossmember, the drain plug is on the bottom side of the crossmember directly opposite the hose.

Good luck

How do i change my oil in my 1999 Harley fatboy


From the right side of your bike, look for a large hose coming out of the backside of the oil tank at it's lowest point. Follow the hose down behind the transmission on down to a clip on the lower tube of the frame behind the exhaust pipes. There is a metal plug in the hose. Simply take the hose out of the clip and reroute it below the frame. Remove the plug and the oil tank filler cap and the oil will drain out. Refill with three quarts of 20W50 oil.

Good Luck

I am switching from syn oil to reg hd oil on a 1992 flstf. Do I need to drain the engine case? If so, where is the plug located? Is there anything else I need to be aware of? THANKS


I would purchase a Harley Davidson repair manual or get one on CD from ebay not as much as a paperback and just as good. The repair manual is a mechanics best friend. Remember buy one it is the best friend you can have when doing maintenance on you harley.

The drain plug can be hard to find. In the 2001 Fat Boy, it is in front of the back motorcycle tire between the Fat Boy's rear shocks.

To do the oil change you need to warm up the oil so it drains better.

Tilt the motorcycle to its right side and position your oil catchment container under the oil plug.

Use your wrench set to unscrew the oil drain plug. In a 2001 Harley Davidson Fat Boy, you need a wrench that will fit a 1/4-inch screw.

Drain the oil. While oil is draining from your Harley Davidson, use the time to clean out the magnet and rubber ring positioned under the oil drain plug.

Remove and replace the oil filter after the oil has drained. Refill with 3 to 4 quarts of engine oil. Replace all parts, including drain plug.

Remember the HD manual will tell you how to check the level of primary fluid needed. Each HD is different and needs different amounts.

You check your primary fluid level through the inspection cover, which is the oval cover in the middle of the primary cover. You'll need a T25 Torx wrench to remove the bolts. Have a new inspection cover gasket in case you need it.

Add the fluid through the inspection cover. You can use any kind of oil petroleum or synthetic as long as it does not contain friction modifiers.

replace the gasket on the inspection cover if needed. Tighten bolts finger tight; then tighten the bolts at 10 foot pounds. Start with the top bolt and then tighten the bottom bolt. The third bolt is the right one, and the left bolt is last.

I want to do 30000 mile oil change myself. what do i need to look for or change besides the oil change?


There is an oil drain plug on the bottom of the engine. Drain the oil, as well as replacing the oil filter which is usually on the side. Real easy process. The hardest part is keeping from getting any oil on the floor or the engine.

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?
