This book covers the small Honda single cylinder OHC bikes from 1965-1999...therein lies the problem. There is not enough detail on anything to really do the job well. If you don't have any experience working on these types of engines I would not recommend this as your only guide. Find someone with experience to help you along because you won't find all the information you need here. It tries to cover too much information in a small amount of space and it really doesn't go over any of the gotchas you are going to run into. The procedures are intentionally vague because they are trying to create a one size fits all shop manual. The specifications are pretty reliable, but the exploded views again are only representative of the type and do not cover all the different configurations you are going to run into. I would not rely on this book to get me through the restoration I did, nor the one I am currently doing. Get detailed diagrams parts fiches etc. on your specific bike and use those instead of the drawings here and make sure the procedures this book tells you to do actually apply to what you have in front of you.
