I just got my 8000 mile service, too. I had to put on new tires though. The previous owner had Bridgestone BT014's and they're just way too soft for sport-touring/two up. I went with the Pirelli Diablo Strada and so far I love it. I put on about 600 miles this weekend alone and the tires are great.
So far everything is good with my '03 also.
