SOURCE: my 04 sportster 883 is a converted 1200, seems to

Unless Harley has changed something, I'm not familiar with a vent tube on the left side of a Sportster. I've always seen the vent tube coming out of the cam chest on the right side of the bike. Even the transmission vent came up and over to just behind the oil tank.

On your Sportster, make sure that you're not overfilling the oil tank. There are two lines on the dipstick. When checking your oil, the top line is 'FULL HOT" and the lower line is 'FULL COLD". Keep the level between the two lines when hot. As long as you can see oil on the dipstick, ride the bike far enough to heat up the oil and then check the level.

Otherwise, trace the hose back to it's source and tell me exactly where it comes from.

Good Luck

2000 wide glide blows oil out the primary case why

Hi, Leighanne you know I was just thinking about you yesterday was going to email you to see how your bike was doing were your ears burning? OK back to your question, the primary case is sealed no vent hose, but there is a transmission vent hose on the left side of the top transmission cover that goes towards the rear wheel for about 4" makes a u-turn and comes back. It only spits oil if the transmission is overfilled.

I have a 1976 Harley fx shovelhead.When I shut my engine off oil will spit out of a hose that is underneath my bike,it does not come out when running just when you shut it down.Does anybody have a clue why...

Basically, it's a crankcase vent line.
While the engine is running, the oil in the crankcase is going all over.
When you stop the motor, the oil suddenly stops and just starts to collect as the crankcase pressure tries to equalize with the outside world.
Kinda simplistic explanation.
I believe your bike vents through the case, rather than through the heads.
One cure is to install a catch can:

Your vent line installs on the 90 degree elbow, the oil collects in the can (which needs to be emptied occasionally), and the filter lookong thing allows the pressure to vent to the atmosphere.

Oil has gotten to my stater and has ran out of the stater plug, How can I fix it

If it is just leaking a little, remove the primary cover. Push the stator plug into the primary housing. Clean the plug and hole it goes into with brake cleaner. Apply black silicone to the outside of the stator plug and push back into the hole. Replace the primary cover, and after the silicone is dry, refill the primary. If oil is leaking alot, and the bike is a Twin Cam, check to make sure vent hose on the trans top cover isn't plugged. Twin Cam primaries vent through the trans and if the vent hose is plugged, oil will be under pressure in the primary and force itself out around the stator plug.

I have 97 custom fxsts S&S cases I tried to start it and all the oil ran from a rubber hose under the frame appears to be a vent

The engine "sumped". This means the oil drained from the oil tank into the engine crankcase.The hose is the crankcase vent. Start the bike with a pan under it to catch the oil coming from the vent hose. Run the bike to operating temp, then check the oil level. Top it off as needed.

Where is the oil drain and how do you refill tranie fluid

The oil drain on your Sportster should be on left side of the bike below the battery around the rear of the primary case. It'll be a short piece of hose with a metal plug in it or a hose that appears to plug onto the frame. Simple pull the plug or take the hose loose and the oil tank will drain.

On the transmission, you remove the top inspection cover of the primary case to add the oil to it. The primary and the transmission share the same oil.

Good Luck

Changing fluids

Trans plug is under the Primary cover ( Left side ) and the Oil line is under the frame on the left side. Look for a oil line with a plug attatched to it. Run the bike up to operating temp. Primary and trans are the same thing ( Sport Trans fluid ) 1Qt in the primary ( fill throught the little cover on the side of the primary, and fill the oil through the oil tank. Put a little oil in the filter too, before installing, this will give the motor a little bit of oil until the rest of it makes it way through. You'll also need 1 p/n 11105 for the drain plug on the primary.

Gear Box oil change How do i do it??

Trans fluid and primary fluid are the same oil , The drain plug is under the laft side primary cover. 1 qt of oil goes in the inspection cover on the top side of the primary cover. The oil drain is a hose under the left side by the frame rail. Look for a oil line with a plug. fill with approx 3 qts through the oil tank. Make sure you get the bike up to operating temp before dropping the fluid.
