This is what I used to fix my 03 883c.

Stock take-off parts from my Nightster.

Works great...no more drips and the filter bolts to this piece instead of just sitting in there.

Awesome lookin Nightster MReed''''glad you found a fix. I don't have the stock carb backing plate deal, I have the SE kit on mine.
It's just odd to me that the new leak started after I installed the 'horseshoe' breather. It's almost like installing it created a pressure build-up on the rear head and now it's leaking.
I am going to try removing the 'horseshoe kit', go back to square one, and see how that goes.
If that doesn't work, whatever I do, I want to be sure it's going to be the fix. The HD dealer guy said the breather kit would work, so i'm not going to him for advice anymore.
Anyone have a similar deal like i've described?
Peace.

I HAD same problem. Mech at the dealership said do NOT use synthetic oil (it is too thin)& be sure NOT to over fill the oil. No more problem.

you have to buy a oil breather kit there is umbrella flapper valves that goes bad every few thousand miles in the rocker boxes harleys answer is to burn the oil in the cylinder but that causes oil to burn and slug up on the valves and pistons and foul out plugs so just spend the money on a oil breather kit ! Harley knows about this problem and would rather you bring the bike into them and tear the whole top end apart for $2000 then install a $25 dollar breather kit from ebay or they charger $130 for it and claim they have no idea what your talking about !

I've tried putting a hypercharger air cleaner with there breather set up. also running my owe breather setup down to the bottom of bike .But i still get alot of oil out of my air cleaner. Right now i have syn 3 oil in it with a hypercharger air cleaner and breather set-up, vance and hines short shots pipes with torque cones, and i rejetted the carb any help would be great!!!

I don't quite understand, you say you also tried "running your own breather setup down to the bottom of the bike" but you are still getting oil in your air filter and on your pipes? Seems to me if that is the case you must have oil leaking from somewhere else. If all your oil was coming from your breather and you tried running it to go out the bottom of the bike there should be no oil in the air filter. I, on my 2007 Sporty Custom, and my son, on his 2006 Sporty Custom installed the V&H V02 Naked air filter system which routes the breather tubes into the intake of the throttle (my bike) or carb (sons bike) and have not had any problem with oil on the filters since. We also don't fill the oil tank more than half way between the add and full lines on the dipstick.

Coincedence? I hate chasing problems and making things worse...shitzkie

Rocker box leaks are pretty common. Mine just started leaking. The gaskets are precisely made with very little squish to them. After a period of time from being squished and then expanding again during heat up and cool down they loose their elasticity and remain squished. Nothing to do but replace them.
I have an S&S carb and had an S&S teardrop AC. The vent tube from the heads dumped any blowby straight in on the filter. I replaced the S&S AC backing plate and AC with a carb breather bracket and K&N filter that breathes through the bracket and doesn't have any hoses. The holes in the breather bracket open up to let the heads breathe on the engine side of the filter so any blowby is sucked into the engine the way it was designed to let the heads breathe. I haven't had any problems with oil outside my engine yet.
