When I purchased my 2004 Varadero last week the seller included the Haynes manual, which is a useful tool in terms of photographs, etc. However, there are some specifications which I find better organized in the official Honda service manual, as well as a better documentation of the "correct" procedure for certain things. I searched on here and was unable to locate a PDF copy, and various internet searches revealed lots of French and Italian versions.
Finally after 2 days of searching, I found an English version and now have a very good quality PDF of the 2003 Varadero Service Manual and the 2004 Varadero ABS addendum. If anyone else is searching, please send me a PM and I can save you quite a bit of time.
