I have an '04 Mastiff. I also have the factory manual, and in my opinion, you can "source" them in the nearest garbage can. It is a TOTAL waste of money. It covers topics like "lefty-loosey, righty-tighty", proper tire inflation procedures, etc. If you're trying to accomplish a task that actually requires you to have a tool in your hand, the manual tells you to take your bike to the nearest authorized Big Dog service center. Your best bet is to do a search on this site for maintenance and repair posts, they're much more helpful. Gasman used to post a ton of really good "how-to's". There is also some very good info on the s&s website. If you're looking for torque values or anything like that in particular, pm me and I'll grab my manual out of the toilet and try to find it for you.
