My thoughts rather than mechanical advice is: bring it back to the dealer for them to take care of it. I don't know where you live because you didn't include that information in your signature line (you should) so don't know what you mean by "cold"? But when we had 3 to 11 degree weather/temperatures a couple weeks ago my bike started, ran and performed fine. It's a pretty stock 2006.
My body, that's another story after only riding a mile or 2.
This is the second 2019 a new forum member had had issue with, a different issue. How the hell hard is it to for a dealer to prep one of these, they are so simple. It's a solution your dealer should be taking care of. When I do buy something new it isn't so I can learn to make it run. Don't let them off the hook. Concern could be if you do something to the bike and it's the wrong advice you maybe legally cutting them out of the responsibility picture.
If it was a brand-new car would you start working on the transmission yourself?
