Bill, if you are thinking of going with Scooter's advice, it would be good for you to get, in writing, his guarantee that he will pay for a valve job on your engine, IF it should ever be required. I stress again, that these are exhaust valves, which run hotter than intakes and yes, maybe you do have some carbon build up, but that makes the situation even worse, as the carbon on the valve seats will act as an insulator, restricting heat transfer from the valve to the seat even more. That carbon can also become super heated and contribute to blowing a hole in the valve face.
Not every ST1300 owner in the world is on this site, so to say that it is unheard of here means very little. Also, there are those that play roulette with things like this and then are rather reticent about admitting their errors on a forum.
If Honda thought .007 was OK, it would be spec'd as such. Are you going to wait until the measurement reads .006? If a valve has gotten tight, it isn't going to loosen up again.
If they are within spec, leave 'em alone. If out of spec, they need adjusting.
