Probably the best advice I have read here. After doing a little research, it is the ethanol that is the problem. Gasoline with ethanol absorbs moisture and only has a shelf life of 90-100 days. Fuel without ethanol can last a long time and with the addition of stabilizer it can prolong that storage for well over a year. Gasoline that sloshes around in a tank in hot weather (like a boat fuel tank) can also develop gummy deposits, but not a problem for the Rocket as we know it doesn't have enough time to sit around in the tank for long.
In the future I will be looking for some ethanol free fuel for winter storage making sure I run a couple of tanks through before putting my bike up for the season. I generally use some sea foam and stabilizer as well making sure my tank is full to help prevent moisture from forming in the tank.
As for bike itself, I keep mine sealed in a cargo trailer with a small fan running to circulate air, I keep an infrared heat lamp on, an Optimate to maintain the battery, two or three bags of damp-rid to help absorb moisture and last but not least...a small ceramic heater running on low. The wife does not like the electric bill adding about $250 to our bill for the whole season worth of energy.
The real issue here, aside from gasoline, is the formation of moisture on your chrome and metal surfaces. I have seen the chrome on several bikes develop microscopic pitting from moisture over several seasons. In the spring when I take my bike out for a ride, I find it just as pristine as the day I put it away. No, it's not warm in the trailer, but circulating air around and maintaining the heat lamp prevents moisture from forming on the surfaces. If you really want to go crazy spray some ACF-50 on those surfaces. Here in Michigan we can get some really damp winter and early spring days. What I have described above has been the only effective solution I have found to totally prevent problems at my home storage site.
