HondaMan,
I'm a printer and just want to throw my $.02 in. I bought just about every CB750 manual I could get my hands on when I got started. I definitely prefer spiral or 3 ring binders, and color pictures are far more helpful than black and white. But one thing no one has brought up that always bothers me is getting my shop manuals all greased up when turning pages back and forth while working on a bike. I would like to suggest printing your book on a synthetic paper and possibly clear coating the pages as well. Synthetic paper is very tear resistant and is also oil, dirt, and grease resistant. Clear coating the pages would make them even more so. Just wipe the page off with a rag. If you'd like, I can even give you a price on printing the project for you. I'm really looking forward to seeing the finished product!
