I think if you simply keep the venting as designed you will not find it run any different. IME there’s absolutely nothing wrong with a bit of moisture entering an engine. They even make water injection kits to address high compression and boosted applications.
You are looking at a sitting, developed puddle that would never have happened if the breather tubes were installed into the intakes as designed.
Humidity and temperature differentials create moisture. Collecting and disposing of the moisture rather than letting the engine injest It is simply not necessary because the moisture evaporates instantly from the high heat in the intake ports and valve. And there is so little oil in the brew it it has no affect.

honestly I've never bothered with it and have subscribed to FLTR117 opinion above..I think it's an exaggerated perception and real world non issue, certainly not worth the trouble to me anyway. just not something anyone I know of has ever done and ride with plenty of long time owners with high mileage bikes. as mentioned, the amount we see in these pics would be time released so to speak in small increments and evaporated...is it better to have none than some going into your engine, of course, does it really make a significant difference when it does, I'm not buying into that..not worth the hassle or worry imo..Harley owners are a fickle bunch and fuss over too much stuff..I also think some spend too much time chug a lugging these and need to not be afraid to 'blow the carbon out' often

I run my oil 3/4 low on the dipstick on jiffy stand and I will get a oil mist in the bottom if my stock air cleaner, that's 25 dollars every 1,000 miles give or take plus fuel milage goes down. I know I can get a stage one kit and clean my filter. I'm keeping this bike stock. Catch a can takes care of that problem plus that oily mist is a form of acid you are putting in your combustion. Same reason you change your oil before you put it up for winter.

I've never had a problem with excess dripping oil, I keep the oil level in the middle of the range. I've read some smart guys here and elsewhere, engine builder and tuner types, that don't pay attention to this "issue".
My bike is new now, I'm going to use the stock venting and keep an eye on it. I have an opened mind so if I have this excess dripping problem I'll do the fix. If the engine eats it without leaving a mess, I'll probably never know.
