130 miles one-way? When I saw "roadtrip" I was thinking iron butt, not daytrip. I did 230 miles round trip last Saturday just to ride up to the Iron Horse Saloon in Ormond Beach to get lunch, and my only "preflight" checklist included tire pressure, oil level, lights test, and lubing the chain. Of course, I keep mine in a good state of tune, and I know my charging system is working like it should, and It's got a new battery. 130 miles won't even burn a full tank of fuel, and should get you near halfway home before you even have to stop for gas.
Like Stev-o says, go through the 3000 mile tune up (unless it's already been done recently), lift the front wheel, check for "notchy" or "grinding" of the wheel bearings. Do the same for the rear. Check the chain and sprockets for excessive wear if you are unsure of their mileage. The front sprocket wears faster and will show greater signs of wear as they rack up the miles than the rear sprocket will. I've ridden chain and sprockets until the teeth on the front sprocket were actually starting to bend over at the tips (of course I was young and dumb and broke).
Unless your cables are sticking (which might indicate frayed cables) all you should have to do is lube the cables. I've got 60,000 on my cables and had no reservations about the 3000 mile "roadtrip" I completed last June from Central Florida to Ohio and back.
Testing the charging system is easy, there's a good write up for diagnosing a 750 charging system (not familiar with the 550, but imagine they are similar) in my signature.
Make sure wheel/axle bolts are tight, handlebar clamps are tight (pucker factor increases when you try to stand up on the pegs while rolling down the road and the handlebars rotate under the force of pulling your self up on the pegs), make sure you don't have any spokes loose to the point of rattling, drive chain lubed and tensioned properly and not excessively worn, tires aren't more than six years old and properly inflated and not excessively worn, nothing else dangling or grossly out of place. You've left out a lot of details about the condition of the different systems on the bike so it's difficult to know what you've done or what you might have neglected. If you've covered everything I've listed here then you should have a bike that I would have no reservations about taking on a 260 mile "daytrip".
Last spring I did a 500 mile "daytrip" (round trip) up to Savannah, GA and back, again just to get lunch.
Jerry and Sean have good points as well.
