Oil leaking from air filter 2006 sportster - 2006 Harley Davidson XL 1200 C Sportster Custom

Check all your vacuum lines for kinks and/or blockage. Most of the bikes I've had this problem with are due to a blocked vacuum line.

If I understand you, the leak is coming from the inspection cover for the primary chain. There should be an O ring on that plate. If the cover is leaking when the bike is off you have way to much oil in the primary. The primary only takes 1 quart of gear lube, I use Mobile 1.

I think you can find the oil drain on the left side of the bike down low on the frame right behind the engine. It's a large diameter hose that plugs onto a stub on the frame. Some are located just below the battery tray and some are lower on the frame down by the rear of the primary case. Drain the oil, change the filter, refill with oil, and you're ready to go.

If you want to change the transmission oil/ primary oil, the drain is underneath the bottom of the primary at the very rear of the primary.

Three quarts of engine oil and a quart of primary/transmission oil.

This is a common problem since the EPA started requiring that crankcase emissions have to be recycled through the engine. Usually, it's not a lot of oil but if it's real bad, i'd recommend replaceing the umbrella seals in the center piece of the rocker box covers. Take the bolts out of the rocker box covers and look at the corner nearest the carb on the center piece. You'll see an "umbrella seal" in this corner. Simply pull it out and pull a new one in exactly like the old one was in. Replace the rocker box covers.

Now, if you'd rather not have the oil mist in your air filter, there are several aftermarket kits that allow you to re-route the crankcase vents.

Good Luck

Sounds like you're overfilling the oil tank. Always check the oil with the bike on the stand. There are two marks on the oil dipstick. The upper mark is "FULL HOT" and the lower mark is "FULL COLD". Keep the oil level between the two marks and never "top off" the tank when the engine and oil is cold. As long as you see oil on the dipstick, ride the bike until the engine is at full operating temp and the only add oil if it is below the lower mark. Never fill it to the top mark. Your Sportster holds three quarts of oil that is pumped into the engine and then back out. The 1983-1985 XR1000 Sportsters, the hot rod Harleys as they were called, on held two quarts of oil. I've seen hill climbers that had custom oil tanks on them that only held a pint of oil. As long as you can see oil on that dipstick, you have enough oil. If you're getting so much crankcase blow by that your blowing oil out of the tank breather tube, you need to run a compression or leak down test on the engine to check for ring wear. Also, I've seen bikes do that when the needle and seat in the carb was bad or the accelerator pump diaphragm bad. Smell of the oil. Does it smell like gasoline? If so, you have carburetor problems and gasoline is running into your engine diluting the oil and adding volume to it.

Good Luck
