Seems like we've had more "winter" than usual down here. For the past month, highs have been in the 40's-50's and/or it's been raining. Got to the mid-60's today, took the 1K out for a romp. Next week we are supposed to get lows in the high 20's. Thankfully for only a couple days. I feel sorry for you guys up north.
On a side note, while riding today I could hear an intermittent sucking/whistling sound coming from under the gas tank area.
Could only hear it while going slow or stopped. It would do it for a few seconds, then stop. I let it idle for a few minutes when I got home, but it didn't do it again. My initial impression is that it's cooling system related, but we shall see.
