My 2011 lost the crank and required a rebuild. This was back in 2012.
It was under factory at that time. The shop gave me a little crap about not running Harley oil. I explained what Magnuson–Moss was and they stopped giving me chit. LOL
They fixed the bike, but I never rode it again.
I traded it for a new one before the repairs where complete.
I just did not feel like dealing with it after that. It may have went 100 miles or 100,000 before it broke again. I just did not want to deal with it.
Some will say as long as its under warranty, keep it. Makes perfect sense for some. Just not me, I want the bike running and want to feel safe on long trips. With a bike that failed once on me, I can no longer do that.
I know some will say that they can all fail at one point or another. I do understand that, and it is a valid point.
It's just in my head, once it fails on me, I can no longer ride it feeling safe.
Just my thoughts on this.
There are reasons to keep and reasons to not keep.
We can offer all the advice in the world, in the end it will be how you feel about it.
Good luck no matter what you decide.
