I am the new owner of a '99 Polaris Sport 400. I am going over the whole machine right now. I want a good maintenance guide, but nothing that I find seems to cover the '99 Sport. The ones I find are very general, and cover many years and many models. Is there anything better than the Haynes and Clymer manuals? For my cars I have the service cd's that the shops use. Is there anything like this for us?
