I ended up just getting two extra sets of outerwear prefilters... When it seems like the prefilters are getting wet or frozen I just swap in a new set. One extra set would be fine for any normal day of riding even in deep snow, but I take a third set just in case.... Nice to just have them tucked in my pocket and takes only a minute to swap.
I also wanted to add to this thread that I ended up taking out the glasspack and swapped it with an R1 muffler.... The R1 muffler is oval in shape and with a few welds fits great under the tunnel.... Also the sounds is great, just like a street bike. I think I got the stock R1 muffler off ebay for 15 bucks.
