oil puking ?
I have a 2014 Classic and noticed when I replaced the air cleaner that it had been puking oil. I replaced the air cleaner and continued to keep check on it. I have noticed that it is puking oil out the front head and nothing out the rear head. I have lowered the oil level but have not had the opportunity to give it a ride and check on it. Why would it only puke out the front and not the rear?

That's called blow by.
If you replaced your air filter with a super sophisticated one that flows better, oil will puke out of the crank case breather holes. Maybe the front breather tube is positioned in a way where it craps oil out. reposition it and see if that helps

It's a bug sucker so not able to change the routing of anything. There was also evidence of puking in the stock filter. This was pretty heavy the stock filter was saturated and dripping in the breather housing. I was running 3.5 qts of oil and I lowered it to 3.0 as I read that this is the number one reason for excessive blow by.

^^^^this works. Do not EVER put 4 quarts in. I used to love when I went to the dealer to buy oil. I'd bring 3 quarts up to the parts counter. The parts guy would say aren't you a qt short? I'd say why buy 4 quarts. The last quart ends up saturating the air filter. He would look at me with this blank look like I didn't know what I was talking about.
Yup,on my 09 96' i find even with an ultracool oil cooler that increases oil capacity a bit & still found that 3.25-3.5qts is max crankcase oil lvl i can run.
If i run more then 3.25-3.5qts oil there will be issues with more oil mist & or blowby being vented thru the crankcase breather system into the stock air cleaner assembly soaking the airfilter itself with oil or it's sent out to an aftermarket crankcase breather setup if the motor has one on it like i got from DKCustoms & installed on my bike .
The external crankcase vent system eliminates the motor from ingesting the hot combustion/crankcase gases laden with hot oil mist into the intake increasing engine temp,oil fouling air filter along with also prematurely carboning up the motor more then normal making it more likely to detonate & decreasing its overall perf too.
So i rec the OP go to an external crankcase vent system ASAP to avoid the above mentioned issues.
