I am on my 5th bike and just bought my first wing last month. I saw a clymers manual while shopping for some lights and picked it up for $30 bucks. I should have known better but was in a hurry to start tearing into my project. A week later I found a clean service manual on Ebay for $35 plus 7 for shipping. It is by far the best I have seen for any bike or truck.
It also has all the electrical schems in the back with a troubleshooting guide.
There might be someone here that could tell you that there is some info in the clymers book that isn't found elsewhere but I have stripped off 126 pieces off mine so far and the few times I couldn't wrestle something off, the service manual showed me the reason and solution.
If you search here, I think you can also find it on cd but I am old fashioned and still like to see it on paper. I have 2 computers but not willing to sacrifice one to the grease in the garage either.
Either way, you can find a lot here and maybe better ideas than mine.
