Hi, welcome to the forum, and thanks for your service. I also looked at the Honda CB500, but eliminated it after seeing the Z650 and impossible, labor intensive valve adjustment procedures (only because of time getting to the valves, the Z is easier to get to).
The valves don't need any adjusting until 15,000 miles and everything else is doable by the owner, just keep receipts of oil and filters. I have always printed out the maintenance schedule and mark on it in red what and when I do them. There is no reason to see the dealer until 15,000 miles, legally. I am not even having them do the 600 mile service. Like you, I can do it all. If you log on to kawasaki.com, you can download the owner's manual in a pdf for free and peruse. Ebay has the factory service manual for $50.00, a $25.00 savings from dealer.
