I do understand what you mean. I am in a highly technical field and spend inordinate amounts of time writing up software-related information that obviously people don't read but expect me to explain in person.
I think, though, the question might not have been motivated by ignoring the manual but by asking people on the site their opinions and how they might vary from the manual. I have gleaned very good information off the site that either was not covered in the manual, was covered in a cursory fashion in the manual, or was contradictory from the manual. In this case, I wonder (as I am not a mechanic) if the maintenance schedule might vary from what the manual says based on people's opinions or based on riding/environmental/seasonal conditions. Probably not, but perhaps that was the motivation for the question?
I trust there are no dumb questions on this board!
