A valve check is relatively easily accomplished, and really ought to be done at this time. Most checks at this stage are either good, or some may need to be re-shimmed. But once it is set at around 15-16,000 miles you should be good to go for 30 and 45,000 checks.
There is a lot of 650 valve check info both here and on VSRI. Get a service manual if you don't have one already, and combine it with the tribal knowledge...you can't go wrong.
The most important application of a torque wrench is on the cam covers; too little and they'll loosen up, too much and they shear the bolts when you start it.
If you have to adjust shims, make sure you pull one cam at a time. There is a neat trick to trip the cam chain tensioner without having to remove it (the rear cylinder tensioner is pretty inaccessible), so that you can lift out one cam at a time if needed. Secure the cam chain to the other cam gear with a small tie-wrap, just to make sure it doesn't move. Get the intakes set and reinstall the cam, then tackle the exhausts if needed or vice-versa.
Besides any shims needed, you'll need a gallon of coolant to replace what you drain out. For the shims, I signed up for a loaner program on VSRI; a small fee for shims used and shipping to the next person.
I've done 2 DL650's and my DL1000, and it's not a bad job at all. Just read the manual before, during and after the check.
And save the beer for when she's buttoned back up!
As for other maintenance, a throttle body synch and throttle position sensor adjustment is also easily accomplished on an 06 and earlier 650. And you should be due to replace stock plugs; I went with iridium.
I'd offer to come down and help, but TPA is a bit of a haul from here!
