I only store but one of my bikes in the winter (The little '75 CB200T that I don't ride much.) The fact is that it is better to ride year around if you can. Riding the bike until it is fully warm - 20 miles, 30 minutes every two to three weeks, will keep everything, not just the engine, loosened up.
The traditional advice if you store for over 3 months is to change it, but I do not. Here's why. The primary reasons to change the oil after storage are to get any water out of the system and to drain any sludge that has accumulated. However, if you drain the oil without first running the bike a good long time, and getting it thoroughly hot most of the sludge won't drain. And, if you get it nice and hot and keep it that way for, say, an hour of moderate riding, then you won't have much, if any, moisture left in the system anyway and any sludge will be suspended in the oil. In your case, with only 1000 miles on the oil you won't have accumulated much new sludge anyway.
On the other hand, if it worries you, change it. Sort of like changing oil every 1000 to 3000 miles. I don't; never have, and have never had any adverse effects from my "benign neglect." Others would go nuts worrying about not changing oil by at least 3000 miles. Life is short. Do what makes you feel good, but just don't confuse that with necessity.
Just my opinion.
