Where is your bike being stored? If its garaged kept, you may not want to fill it all the way. That way, when you're ready to ride again, you can top off with fresh stuff. Stabil keeps the fuel from becoming gummy, but still cannot keep fuel "fresh". Combustibility (I think thats a word) will suffer in time so you'll have a tank of bad gas. However, if the bike is outside or in high humidity, fill it up and worry about bad gas later. The bandits only hold just over 5 gal. so not a big deal if you have to empty the tank. The gas in my in-law's motorhome went bad with a 70 gal. tank, that was a problem.
