Change the oil in a 1998 harley Davidson fat boy?

Many people do this half way. They do not drain the old oil out. Please follow this link....http://www.twowheelsforever.com/how-tos/how_to_do_a_complete_EVO_oil_change_and_flush.html.....or....

How to do a Complete Softail EVO Oil Change and FlushThis how-to is applicable to 1984 to 1999 Harley Davidson Softails, although it may be helpful for other HD Models, especially with Evolution motors. These pictures and steps are from a 1993 FXSTS.

Step 1:Warm up your motorcycle to normal operating temperature. This will help the oil drain easier, and also make sure any contaminants are suspended in the oil. Locate the oil tank drain hose, which is clamped to the frame to the left of the transmission, below the starter.

Step 2:Loosen the hose clamp with a screwdriver or a 1/4" socket, and remove the hose plug.

Step 3:Drain the oil. Once the oil tank has completely drained, replace the hose plug and tighten the hose clamp.

Step 4:Locate the oil filter at the front of the engine. You should be able to twist it loose (counterclockwise) with just your hands, but if the person that installed it overtightened it, you may need a filter wrench.

Step 5:Wipe the oil filter mounting surface clean with a rag.

Step 6:Dump a little fresh oil into the new oil filter, and be sure to lubricate the filter gasket with some of the oil. Reinstall the oil filter, twisting it clockwise until the gasket just touches the oil filter mount, and then tighten another 1/2 to 3/4 turn. Do not overtighten.

Step 7:Add 2-1/2 to 3 quarts of fresh oil to the oil tank, and reinstall the filler cap. Most people stop at this step, and don't flush all of the dirty oil out of their crankcase. It's a little extra effort, but it's worth it.

Step 8:Locate the oil pump return line. This should be the right-most hose (the one closest to you when looking at the oil tank from the right side). Loosen the hose clamp. If you've never had this oil line disconnected from the oil tank, you may still have the stock hose clamp. You'll have to destroy this clamp to remove it, but you can easily replace it with a standard screw-type hose clamp.

Step 9:Once this oil line is disconnected from the oil tank, insert one end of a piece of clear plastic hose into the end of the oil line. Insert the other end into your oil pan (or an empty quart of oil).

Step 9:Start your motorcycle, and open the throttle a little bit to get the oil pumping. You should see dirty oil begin to flow through the clear hose. Let your bike run for about 30 seconds, and then hit the kill switch and add more oil to your oil tank. You may have to repeat this process several times until you see fresh oil start to flow through the clear hose. The advantage of draining the dirty oil into an empty quart container is that you'll be able to measure exactly how much to replace.

Step 10:Remove the clear hose from the oil pump return line, and reconnect to the oil tank. Reinstall and tighten the hose clamp.

Step 11:Start your motorcycle and check for leaks at the oil tank drain hose plug, the oil filter gasket, and the oil pump return line. That's it!

Is a Harley Davidson fat boy too much bike for a first time rider?

Yes. If you are a first time rider and you insist on riding a harley then I would suggest that you get a sportster. But first I would suggest that you take a motorcycle safety course. I have been riding for a long time and I have seen people start out on large bikes. It's not pretty. Start with something that you can handle. A Fat Bob weighs in at around 703 pounds, a Fat Boy around 714 pounds and a sportster around 583 pounds. That's a lot of weight.
