At least the 2017 is not directing crank case venting directly to the throttle body. 


TN

    Where else would it be vented?  They can't vent it to atmosphere, since that would be highly illegal.  I remember someone else making that comment before and I looked at a parts catalog listing for the air cleaner and found the same kind of breather connections and tubes we have on the older models.  I just tried to look it up again but the site I'm using for 2017 parts is down,  probably due to too many people like me looking up 2017 changes.
Here's a pic from the 2017 SE Catalog.

States if oil was overfilled it would dribble on a/c. Maybe you don't have to under fill them now.

I don't claim to be smart....but why would you want your "overfilled engine oil" routed through the transmission (case)?

I may delete this post when someone informs me of my lack of brain cells.  Trust me, it's happened in the past!!

Trust me, you are right on the money.  The comment in that article makes no sense.  The best I can figure is that someone either mixed up the information on the breather system with the information on the oil cooled head system, or they were just making stuff up on the fly after looking at that hose that runs from the rear head down toward the trans on the so-called oil cooled model.  Harley can't dump any excess oil into the trans, since that would overfill the trans.  They can't dump the crankcase fumes into the trans, because the trans is vented to atmosphere and it would be illegal to use that vent to dump crankcase emissions to the atmosphere.  If there has been any improvement in oil carryover to the air cleaner, it would have to come from improved oil separators in the breather system.

I’ve never claimed to be the smartest man in the room myself. I do see where they have re-engineered the breathers in the rocker box, took them long enough. Maybe some HD employee reading this could chime in, or will he? Previously you could’t fill the crankcase to the full mark without oil dribbling out on the a/c, in my real world experience.

I won’t have to worry about it, I’ll continue to run mine 1/2 quart low and vent to the atmosphere. Got to use up my carbon credits somehow.

Well..... except that the Twin Cam engines have always vented to the tranny cases.  Primarily for crankcase overpressure but that was never an absolute.  Since the MoCo still likes to prescribe the same fluid for the engine and the transmission one could understand a weird logic that would suggest overpressure or over volume in the new engine be dumped in the tranny.  If for environmental reasons if nothing else.  Ideally one just wouldn't overfill.  But this is the MoCo we're talking about....

My bikes prefer to vent to the atmosphere also.  It helps increase the Global Warming, each of us should do our part.

Many scientists point out that Sun will probably have big decrease in sunspot activity, which will mean less heat coming to Earth.  I can hear the Global Warmists now:  "Yeah, human CO2 caused global warming, which caused the global cooling...just like we said it would."

Took a test ride on a 2017 last week to compare it to my 2016 CVO.  Biggest impression is the lack of mechanical engine noise and smooth idle - definitely an improvement.  Power, however, was about the same as my 110 (my 110 was dynoed after an exhaust change, so I'm getting a little more oomph there).  No change in temperature - my 2016 is a cool running motor, far cooler than my 2008 CVO was.  Oddly enough, the cooling fans ran on the 2017 where my 2016 fans rarely ever run.
Suspension felt no different and handling was the same feel as my 2016.
My biggest concern is HD's record for having problems with the first year motors.  EVOs had leaky cylinder base gaskets, Twinkies had cam bearing failures, the 110s had head gasket issues in the 2007 model year.  So, I'm staying away from them till at least 2018.  At besides, I have a 2016 that has had zero problems in its first 9000 miles.  And, I don't care for the colors on the 2017s.

Rode a 2017 Street glide special yesterday.  It had the HD stage one kit, slip ons, hi flow air cleaner and a HD map.

Motor is very smooth, only a very little harley shake, which I like.  Very little mechanical noise from motor, which I love, no longer sounds like something is soon to fail.  Transmission is smoother.

The power of the 107 with the stage one was very similar if not slightly better than my 15 SERGU with a Fullsac exhaust system, hi flow air cleaner and a TTS tuner with a good tune.  Really impressed with the low end of this new motor.  I'm sure with no cat it will make more power than a stage 1 110.  Really love the new motor, can't wait to try the 114.

Front suspension is a huge improvement.  Much firmer, felt like less flex pushing the curves.  Way less dive under hard braking, felt more planted in the curves.  Rear seamed improved also.

That's kind of what I got out of the ride as well, not sure I would want to pay the difference to the CVO. But I haven't seen a CVO RG yet. Hope its a Hot rod version like the 09. Wish there was one I could rent for the weekend so I could spend more than 10 min on one. My bike at 202/178 is a tough act to follow but it beats you up after a while.

I AGREE THE COLORS ARE VERY UNDERWHELMING

Luckily I have the most reliable, blah, blah, blah.      

I just replaced the noisy lifters and cam in my 22K mile 2015 CVO.  So much for reliable.  At least I wasn't on the road in BFE or some other gosh darn freakin place.

So...I guess my new M8 doesn't have a high bar to exceed, eh?  You definitely need 2 H-Ds to be on the road constantly.

One HD and one K1600GTx would work as well
