Do your own work and you'll be a better rider for it. You know exactly what was checked, the condition of the bike on a personal level and no the price isn't worth it.
What needs to be done:
Change oil and filter
Clean and recondition the air filter.
Every nut and bolt you can get your hands on needs to be removed and have blue loc-tite put on them.
Check chain slack and adjust if needed, tho I doubt it will.
Buy a can of Chain Wax from the dealer,"others have great success with other lubes", and keep the chain lubed. About every 400-500 miles. It should be cleaned when it looks extra dirty.
Some say to check your valves at this point, but I waited till the 1000 mile mark and my valves were fine. I did have to replace the shims for the valves at the 6000 mile mark.
Here is a great link with a lot of mods and every day procedures for doing many of your own maintenance items.
Also the factory batteries are known for boiling away the fluid, so check your battery two or three times a year and keep it filled to top level. I suggest purchasing a good maintenance free battery for worry free service.
We also bought a tube of Di-Electric grease and pulled every electrical connection we could find and filled them with the grease. Especially those back under the rear fender.
It sounds like a lot of work, but you can break it up into several sessions over a couple of weeks.
