As the others said, don't start it with the e-start when it's cold, specially at 30*. Did you ask the dealer to tell you what size jets they used? It's very important that you know what jetting specs the bike is using, so that when the weather gets better you'll have a point of reference if the bike isn't working right. Have you done all the free mods yet? If you haven't, you might want to take the time to do them, and then when the weather improves re-jet the bike so that it runs right. The jetting database thread is really helpful to get the bike running right. I'd say forget the dealer, it's much better to learn how to tune the bike yourself.
