Time for the 4th engine in my 2017 CVO Limited... here we go again!

My guess is that it's just a matter of time until all M8's suffer the same fate. I'm only sitting at 2600 miles and I'm wondering if I should just move onto a different bike all together. i was planning a road trip this summer but not sure I want this hanging over my head and getting stranded somewhere.

my dealer and a Harley tech were pretty honest (I hope) before I bought my bike. They said the twin cooled and stage 3-4 kits have seen some growing pains, but the standard 107 (I was looking at road kings and street glides) have been reliable so far. Obviously there is a percentage of failures with anything but you get the drift. Called a random tech in a random state and asked what he has been seeing, same response. Could have been bs, but I decided to get thr extended warranty just in case and have faith that the moco cant afford to have catastrophic failures on every bike sold. Just not doing stage 4 and enjoying it is my plan.

Come on guys, did you learn nothing from the evo and fathead years. Harley builds an engine, sees if it runs then sells the bikes to the customer to do the real world testing. When engins go bad they replace them and send the bad ones back to the mother ship for the post mortums to find out what they need to change for the next model year!

It defies logic. There has to be something specific to these cases that causes this to happen... just has to be. Something different about the particular bike that somehow is affecting sumping (road harmonics? bad oil cooler? Brakes dragging so it's putting unnecessary strain on the engine at all times? I don't know).
The issue also seems related to performance upgrades. Yes, it CAN happen to any M8, but based on the reports we've seen, it seems to happen most to big CVO engines, and to Stage IV. Heatwave had a perfectly running M8 for a while, stock, but once going back to Stage IV it sumped again.
There should be about 250,000 M8s on the road now. Badcooky reported that HD Australia told them that a grand total of 1.2% of bikes had sumped, and that the problem was almost entirely confined to 2017s. We know that it's not exclusive to 2017s. Almost all of the reports are from touring bikes. Most of the reports appear to be from CVO owners, or Stage III/Stage IV owners. So will it happen to all M8s? Theoretically possible, but probable? I wouldn't think so.
For what it's worth, I got concerned enough initially that I put a 4-year Discount ESP warranty on my bike; it was $1000 and kicks in after the factory warranty ends, so six years of coverage. May be a wasted $1000, but then again, maybe not, only time will tell.
