To your private driveway mechanic YOUR bike is a $200 bike.
A lot of mechanics at shops are no different. Even dealers aren't much better; they're just armed with factory service manuals.
So where's YOUR factory service manual? Get one if you're going to keep the bike and work on it. If you have enough faith that team of engineers designed the bike well you should at least get the proper documentation that states what is what and where it goes and how it gets there.
Notice how I wrote factory and NOT haynes or chilton.
Working in a bike (especially a fast one) isn't supposed to be a puzzle. Puzzles are games: this is way more serious.
