Chain adjustment is a personal thing. Everybody has a different way of doing things. Factors that enter in to setting chain are Chassis type>>Rear suspension design>>placement of front counter sprocket (Varies from engine to engine) and the use of chain tensioner or not. Maybe if you specified your chassis type and engine type and year you are using. someone with the same set up might jump on.
As far as the book Bob I would recommend it to anyone getting into this particular class of racing, it is a bit old but except for some suspension changes the info is very relevant to anyone getting into this racing class.
Mr Smith does not give me a commission on sales and I very seldom do anything for free, but I know that I have personally given away several of his books to teams I have believed to need help. I also still keep a copy on hand for my brain farts.

TQ You will also need a good heavy duty (Motion Pro) chain breaker and rivet spinner to work on your chain. Most motorcycle shops can get you one. Also over the years I have learned not to use or depend on master links (they come undone at the most in opportune times.) If you will be spending most of your time at one track one chain is enough, if you will be touring you will probably want 2 other chains of different lengths to make gear changing easier.
