When I had my '03 Vulcan, I started it every two weeks or so, and let it get to operating temp, and nothing ill happened to the bike, same with a Honda 500 Silverwing I had, both carb models. I left the battery in the bikes in both instances, rode the Vulcan three years on the same battery, Silvering on two with this strategy.
Everyone bitches bla bla bla, about using the search tool, and in the time you took to type your subtle little anecdote, you could have answered it without the "SEARCH" reference, as I see no one else had the same break-down as you did...
SO much for a community of people that just want to talk and ask about stuff. SO, I will follow suit, and just tell people to SEARCH from now on, as it is ALL obviously here, somewhere already, right? So there is absolutely no need for anyone to reply with anything OTHER than SEARCH then? SO, please, in the future, no one offer any help, just reply with one word, that being "SEARCH." We do not need any, idle chit-chat, and ANY friendly conversation, ever... No stupid smilies either... Reply with One word, a magic word too, SEARCH
