Mike you really need to let off some steam! Have a fun ride.
I had valves tight at 600. I probably could've done them later, but I did a pretty hard break in. Of course if things need tightening up before 16k I will jump in and do them, but I doubt I'll need to.
Not needing to remove the cams will make this so much better than my old Ninja 250. That was a PITA to do. Everything was tight come adjustment at 7500 miles.
For those that ask if they should do themselves and are new riders. It may be better for you to fork over the money for the first service. Why? Well in the next 16k(if you even put on 16k before "downgrading") you will learn a lot about how your bike works and may have to "get your hands" dirty doing relatively simple things like oil, chain, brake pads, and other maintenance items. By then you may be willing to try the valve adjustment. It helps to understand what you're doing in there before you do it.
Also buying a service manual is a good idea if you plan on doing maintenance such as a valve adjustment. Hopefully by the time you reach 16k more of us will have done it and can give some insight and maybe some pictures. It's not something terribly hard if you've done it before, but the first time can be a daunting task.
