WHo Knows?
The only ones that have an idea are the ones in HD's warranty dept. Some just swapped the pump out on their own dime. It's a lot I'm sure and not just reported here. Three of the guys I ride with had theirs sump. 2017 and 2018. Bone stock with 3,000 miles, so the engine kit only bs doesn't hold up. It is acknowledged at the dealer I use also.

Update #8...
Back in the saddle again with a "new bike" smell...
New, complete 2019 motor arrived and installed on Friday. After a few tests run Saturday dealer has me good to go. I picked-up this morning. I'm told the 2019 includes a new oil-pump cover/plate that was not previously part of the design. I've got a few rides planned over this next week that should provide me with over 500 miles of opportunity to put it thorough it's paces... Will report back then - hoping that next "update" will be my last on this topic.

Been a blast. Hoping I'm through here...
Adam Sandoval Sumped his engine
Hey Adam Sandoval sumped his Stage IV 2017 RGU with 3000 miles on it and new factory pump. It kills me because I would like to do a stage on my stock 2017 but hearing that makes me want to leave it stock for now. I know people say just got outside HD for kits or a well reputable machine shop, but I would be paranoid about MOCO not acknowledging the true cause so I would know how to prevent this.

Just information to add. My RGU M8 2017 build date 8/16.. 3000 miles on the oil and just came back from a 1200 mile round trip that I was exceeding the speed limit on 90% of the trip. the bike has 19,000 miles on it. Mine is a stock 107 .
Did the test by the book. drained out 2 1/2 OZ and that took about 15-20 minutes of slow drip , drip to come out

I just wanted to check it. Warranty is up soon and in about 2 weeks a Twin Classic sidecar will be bolted to it. So it seemed like a good idea just to check it .
