Why did my engine oil level rise on 1996 fatboy 1340 after fresh oil change

SOURCE: need to find engine oil drain plug on 93 fatboy 1340

The engine oil drain plug is on the right side of the bike. Actually, it's a hose with a plug in it. Look just behind the chrome transmission clutch release cover on the right side of the bike. You'll see a large diameter hose that should be held to the frame by a clip with a metal plug in it. Just loosen the hose clamp and drain the oil from the tank. Remove the oil tank dip stick for faster drainage.

I never pull the derby cover unless I have to fix something. I do exactly what you described and have for 20 years. Never had a problem.

SOURCE: 93 Fatboy oil leaking from vent tube at air

On your '93 model, the crankcase vent is down low on the engine behind the oil pump and it runs up to the air filter through a metal and rubber hose. I don't know how many miles you have on your engine but it you're getting any blow-by on the rings, this will increase the pressure in the crankcase. Most people simply re-route the crankcase breather underneath the bike and plug the hole on the backside of the air filter. Replace the metal line with a rubber hose and put a small filter in the end of the hose. Route the hose back behind the transmission and attach it to the transmission mounting plate just in front of the rear wheel.

This was the way the older Shovelheads were done from the factory for years until the EPA made them start running the crankcase vented air through the engine. In 1994, Harley went to the "head breather" system and moved the crankcase vents to the heads. Still, the oil mist in the vented air builds up in the air cleaner on these models as well.

Good Luck

The Oil Capacity is 3.5 qts. (3.3 L) are you sure you pulled the right drain plug, and drained the ENGINE oil? The engine oil drain hex bolt is located on the right side of the motorcycle and is removed/installed horizontally.
Transmission oil drain hex bolt is located on the left side of the motorcycle and is removed/installed vertically.

SOURCE: oil quantity need for oil

The engine take three quarts, the primary takes 38-44 ounces, and the transmission holds 20-24 ounces. Check the oil in the engine oil tank with the bike on the side stand. As long as the oil is between the lines, do not add oil. When you change the oil and filter, start the engine for 15 seconds and then check the oil. On the primary, stand the bike straight up. Remove the derby cover and fill the primary until the oil comes just up to the bottom of the outer clutch shell. Do not overfill. If you do, the clutch will drag and you will not be able to find neutral with the engine running. Check the transmission with the bike straight up as well. There is a dip stick on the plug where you add the oil. Make sure the oil level is between the lines.

Good Luck
