I would give them a couple of opportunities to fix it and then I would grenade it. These half-assed fixes don't get far with me. If you blow it they will have to replace with an entire new engine. This is not a new problem. It has been going on now for 24 months. Hundred, maybe thousands of bikes are having this problem. Clearly the MOCO engineers don't know what the cause is or they would have made the necessary changes in design months and months ago. Having a warranty doesn't do much good if they can't permanently fix it.

Dealer had bike for a week... Took a few test rides (abt 20 miles around town) and did not experience sumping. Put it on the dyno Friday and ran if for 45 mins and did not experience sumping. In both of my previous situations, summing occurred following an hour or so of highway/interstate riding.
Yesterday was a gorgeous day here in North Jersey so I took the bike out from the dealer for a few hours to visit a buddy about 65 miles away (mostly highway @ 75 mph / 6th gear at around 3,000 RPMs). As I neared my destination I could sense the condition. Smell of oil burning, loss of power, change in exhaust tone and more and more heat pouring off the motor. Let the bike sit during my 30 min visit and checked the oil - down over a quart. Idled the bike for 5 mins to see if it would scavenge back - checked again - no change.
Called the dealer to let them know "we have a winner" and that I was on my way back to them. They were waiting with an open lift as I arrived. The whole dealership could smell the bike as we watched 2+ quarts of oil pour out of the crankcase. Spent quite a bit of time talking about what might happen next (repair options, escalations, new motor, etc.). It is as it is - I'm not bitching and certainly not beating them up about it. Just talking about expectations and experiences thus far. They've been great to work with and appear just as frustrated with the situation as anyone else.
One thing worth noting - this seems to be a recurring issue with the 117 motor, either stock 117s or 114s that have opted for a 117 kit (so I am told). Not necessarily the smaller motors. Hoping to know more during the week. I was very grateful for the opportunity to get a few hours on the road on a perfect day.

Until they change out the engine case with a recently built engine, the issue wont be resolved. What dealer in Jersey are you working with?

I get this emotional sentiment, just not sure I'd advocate putting one's safety at risk unless you're suggesting some sort of controlled environment on your terms...if that engine blows on the freeway unexpectedly, lots of bad things can happen in a hurry out there...just sayin'

My '17 with 8800 miles had the oil light come on July 8th. Dealership replaced the oil pump and I picked up the bike on the 22nd. The bike ran great until the 26th when it lost power, just would not rev. It is now at the dealer going through all the checks as it is sumping and they cannot get it to stop. The have some revised plate coming that they hope will repair the issue.

sorry to hear of your troubles. Its not the dealers fault. Its just very difficult to make a bike sump without running it on the rosd with different loads, road conditions and rpms. Plus it takes more time than most dealerships will commit. It takes a minimum of an hr of riding and sometimes more. I was down the whole path of various oil pumps, then special cylinders and pistons. It still sumped.

My dealer is Tramontin HD in Hope, NJ. I am fortunate to have walked into a fantastic dealership for my first Harley - Truly great people there and they've been doing everything they can to help me out with this situation.
Got word this morning that a new 2019 is being built for my bike - apparently includes a new performance oil-pump plate / cover (?) that finally addresses the issue with the 117 sumping. I might actually have the bike this weekend.
