Every Harley I've had with a built-in system has promised much...and delivered little. They all have been Clunky (capital C intended), loaded with bugs, required torturous levels of work-arounds, are poor quality, break easily and often and cost high prices plus the Harley tax, and are left in the dust by nearly every aftermarket system out there.
When MoCo issues a software update to fix some of those teeth-grinding problems, the result is new problems added on top of the original problems. Eventually you'll pay a tech for 3 hours of diagnostic time/Digital Tech, just to be told "They all do that!"
When you've had all you can take, and drop-kick the bike into the Grand Canyon and buy a new(er) one, you are guaranteed to get a different set of problems...not always better or worse...but at least it won't be the same crank-addicted worm that buzzed around in your brain for the last couple of years.
The best approach is to chit-can the original system and buy whatever quality of off-the-shelf system that meets your needs. Good luck.
