So after the new year I will be traveling for work for the whole year, my bikes will be left unused in the garage/shed for a full year.

I have a few of them and am curious what type of preventive measure I should take to prevent any issues when I get back. I have toped off the fuel with Sta-bil and Startron (ethanol treatment) and rode it about 60 min before putting them up. I think that the same measure would apply to each one, but here is what I have. If there are any special things to look into for a specific bike, please let me know.

1989 Cafe Raced Sportster
2003 Buell Blast
2006 Buell Uly
2008 1125R
2009 Harley Ultra Classic (daily driver year round)
2014 EBR 1190SX (just purchased 250 miles so far)

By the way I'm in CT and traveling to Florida (Riviera Beach and Panama City) for the year and can't take them with me. I am actually looking to buy something while I'm down there and will sell when I leave if anyone knows of a good bike for a good deal (does't have to be a Buell/EBR/Harley). I am looking around craigslist and have seen a couple Street Triples, V-Strom, or FJR's that are enticing.

Cross posting to BadWeb for input also.

Thanks for all replies
