All Harley engines built after 1994 have been what we call "head breathers". In other words, the crankcase ventilation has been routed into the breather through the heads. The requirement of the crankcase pressures being released into the intake system is the results of EPA anti-pollution regulations. Harley moved the vent from the lower crankcase to the heads to decrease the amount of oil blown out by the ventilation system. But, there is a certain amount of oil mist present in the expelled air. The mist will collect in the breather over time and will eventually drip out of the air cleaner. Regrettably, this is a fact of life with a Harley engine and it's design and it is normal.

Now, you can clean the air cleaner on a regular basis to keep the oil out of the air cleaner or you can purchase a kit that exhausts the crankcase pressure (and the oil mist) somewhere other than the air cleaner. I thnk Kuryakin has a kit.

Good Luck

SOURCE: 2003 883 sportster, how do you drain the engine

warm the bike up ,then if you look in between the rear wheel and the engine case on the left hand side of the bike (if you are sat on it ) on the underside you will see a black plate (part of the frame ) and it will have a black hose on it secured by a jubilee clip , remove the jubilee clip place a oil drain pan underneath it and pull the hose away from the frame and the engine oil will drain out .
hope this helps
kind regards

Oil leaking from air filter 2006 sportster

Hi Anonymous, oil leaking from your air cleaner is caused by oil carryover from the engine. For what ever reason the breather system is not seperating enough oil mist and air from the piston downstroke. There are cheap and quick easy fixes and there are more exspensive ones. Start by trying the following:
1. Run your oil level half way between the add and full mark when hot.
2. Run oil breather lines from head into a TEE fitting below carb/induction module then a single line into a mini filter under frame.
3. Purchase Arlen Ness Super Sucker.
4. Replace umbrella valves and realign oil pump
5. Upgrade oil pump and cam plate
Good luck

This 2003 harley sportster has a tilt sensor where is it on the bike and can i disable it?

They used to put those things on the backside of the oil tank and if it's a "normally closed" switch, you should be able to jumper it out. But, I have never disabled one of the switches. I've never had anyone that had a problem with one. As far as I know, it's a safety switch so that the engine does not "run away" if the bike is dropped. I've seen plenty of Sportsters do this back in the days when we rode them in the woods. Drop the bike and the engine would scream wide open for a short period of time before it quit. The old Sportsters (69-70) with the Tillotson carb was the worst about it. That carb had no float bowl and would run in any position. They use the same design on chainsaws.

My 2006 Sportster seems to have excess oil coming from the air filter area, what can I do to fix this problem?

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

Dumping oil out of generator breather tube

Check the oil level, if the fuel runs freely to the carb and runs out it may have filled your crank case with fuel. turning it over with less power than it needs will ruin the starter, battery cables and start relay. Anyhow, if crank case is flooded with fuel clean carb to remove trash,so the float can do its job.Change oil,and air filter,clean sparkplugs. OK if i took a wrong turn stay with me, check pistons for compression.If piston is cracked or the rings are bad or not set,pressure from the piston could escape into the crankcase and blow oil out anywhere.Good luck Mr.Schnot.

2006 sportster xl883r oils plugs and cuts out, no throttle response How can I cure?

I need more information. By "no throttle response" what do you mean? The engine will not rev or it just doesn't respond well when you open the throttle. you could have a hole in the diaphragm in the carb, if it's the stock Keihen CV carb. How many miles on the engine, What type of carb, what type of pipes. I need more information.
