Isn't there a checklist of scheduled maintenance stuff in the owner's manual? Maybe it's in the shop manual, tho - I know I saw one somewhere.
Honestly: if you're able to do oil changes, remove the tires, and adjust the chain, most of the stuff is "DIY-able." You don't really need to pay someone to lube your lever pivots and set your throttle cable free-play, do you? How about pulling the calipers to check the brakes - it's only two bolts?
Understanding that you're going to be on the road and assuming you don't tow a garage behind you, tho - 25k is just a milestone. That is, if you do your "25k maintenance" at 28k, I don't think the motorcycle gods are going to rain lightening on you and the bike isn't likely to just start flying apart. You say it's running great and apparently have already put a bunch of miles behind you. Tires, oil, and chain/ sprockets is all I'd worry about on the road.
I'm always a little leery after doing maintenance: if something is going to leak, shake loose, or otherwise not "take," seems more likely to happen after it's been fiddled with than just randomly. I'd rather have major maintenance done close to home.
