Congratulations! There is an old cliche', "If you want something done right, do it yourself."
Now in the mechanics/dealers defense.
1. There is a thing called a PDI (Pre Delivery Inspection). I don't know what Kawasaki pays the mechanic/dealer to do this service, but usually it is minimal. Mechanics are paid by a system called flat-rate.
Say for instance the PDI pays 1 hour. The mechanic has to go get the paperwork, find the bike, bring it in, get the parts and do the job. Say it takes him an hour and fifteen minutes. He doesn't get paid for that fifteen minutes. None of us likes to work for free and this is a profession. He has a wife and children to feed, a mortgage, car payment. You get the picture. Corners do get cut and most like to stay ahead of the game.
This can be a problem when there is a warranty involving a complicated diagnosing issue. Say he spends 3 hours trying to figure out the problem. He may only get paid by the factory for 1 hour.
2. Services are the bread and butter for the mechanic/dealers. They are usually simple and straight forward. From experience a decent mechanic will know what he has to watch out for on a paticular bike. They know they will lose on another job, so they can make it up on services.
It is a delicate balance between quality and earning a living.
