What check ball???

WHAT???

Not my vintage but I expect likely under the seat with the rest of the fuses/relays etc.

I'm thinkin' your problem is bigger than crank case ventilation, sounds more like a broken compression ring in one of the jugs.

Did you just mess with the carb? Could be an intake leak. Adjust throttle cables for correct freeplay. Then turn down idle via idle screw.

This is what we call "oil sumping" around here. On the soft tail line or any other line of Harley where the oil tank is higher than the oil pump, the oil will seep past the check ball in the oil pump and leak into the crankcase of the engine. When the engine is started up, it will "puke" the oil out. Now, up until the introduction of the Evo engine, the engine would puke on the ground under the bike out the breather tube. Now with the Evo engine and the EPA's regulation that crankcase ventilation fumes have to be fed back through the intake, it pukes into the breather. An even bigger mess. So, what we do whenever we think we've got this situation is put a pan under the shovelhead and panhead bikes, On the Evos and Twin Cams, we take the air breater cover and the air filter out before the fire the engine. It's a mess either way you look at it. I don't think the Twin Cams are as bad as the Evo engines due to the different type of oil pump.
