airbags

Gotta 2001 w900. Seems like when I get in cold weather my airbags deflate. I've changed out the leveler valve only to have it happen again. Any suggestions?

I blew two airbags on my trailer yesterday. I have a couple of questions. I haven't crawled under the trailer yet. Some of my questions may be answered when I do. How are the airbags attached? Are the straightforward as far as taking them out and installing the new ones? Are airbags...
