I did it the first winter I got my 09 Ultra... I bought the PDF version of the manual ($8), no special tools ($0), and had the inner off in about 4 hours... I took my time and it was over the course of a weekend. Got the inner back, and it took about 2 hours to put everything back on. I expected it to be so much more difficult, but it was an easy task if you have just a little bit of mechanical abilities. Oh did I mention I took pictures of everything I removed and needed once or twice when putting it back together, and I bagged everything in regards to the specific area in the manual... not bad to be honest whicha
