Can't get my oil port open/off on my Fat Boy....To check it.

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!

I like hd formula + for primary's but any non synthetic is OK 10-30..oil.. spectro makes a good oil for that 2

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.
