I find reading the Honda, Haynes, clymer and Pittman manuals each give differing advice as do the articles in the Brooklands gold portfolio and personally I find each has it's strengths and weaknesses depending on the job I am doing. For setting points I actually favour an article by Rod Gibson in one of my old bike magazines, I just find following these instructions easier. Part of that is if the instructions rely on you having kit you either do not have or that's not easy to get to in the lock up at the time. One thing without doubt is that if things are not seeming straightforward the stopping to read how it's done is better than getting out a hammer to fix it, then buying new bits, or doing the job twice.
