I found this and wanted to share. I also have the book but the pdf has come in really handy when doing searches and finding the page of the paper manual. I have used it to search "loctite" to see the different loctite numbers that the bike uses so that I could order them as well. You could also search the pdf to see how many times the manual says "serious injury or death". It's got a million uses. You can get it here: http://www.carlsalter.com/motorcycle-manuals.asp
Just go down to:Harley Davidson FLHRC 2006 Maintenance & Repair Manual Full

Price is: FREE

I can't see the pdf replacing a book, but it is a nice adjunct.
Hope this helps someone.
I meant to put this thread in the touring section but it went here accidently.
