its been a while, back for questions!!

hey fellas its been a while since i been on the forums, once i got the new meanstreak a few months ago, i havent gotten off it until now, already racked up 5,500 miles!!! Everyone on this forum is very informative and respectful(not like many other forums i belong to audiworld cough cough) both bikes we bought were great and recommend them- 2007 meanstreak & 2007 900 custom. But now in the northeast it is getting cold(snow actually falling right now) and want to know the best option for the bikes over the winter..we are putting them down in the spare part of our basment which is heated, but what steps shoudl we take to protect the bikes over the cold season. Thanks again to everyone here!!
