Interesting information.
I have a 2017 CVO with the 114. Just had the 10k service done last Saturday. I have had zero issues to date. The tech spoke with me when he got back from the test ride and said my bike is perfect. I asked him if he checked for sumping still and he said no, not unless the owner complains of symptoms related. He said they had a few early on and it is a non-issue at this point. Don't shot the messenger, simply sharing what I was told.
Not taking any shots, you're just reporting what someone told you. But I hope you understand that just because someone at a dealership tells you something is not an issue it isn't necessarily true. In my experiences it is rarely true. And if it was true, why are we still seeing new reports of failures on recently purchased 2018 models? Dealership people have been telling customers obvious defects are normal, they all do that, I've never heard of that problem, etc., for decades. I've often wondered if that is part of the "factory training" they supposedly receive.
