I have an 02-RT and did the valves myself and it was the first time I had taken the right side fairing off. Glad I did.
The return line disconnect was broken and not latching, the alternator belt needed to be replaced, found some wires that were starting to chafe and the valves were too tight the the idle too low.
A dealer had done the valves last year and a TB sync. Just setting the idle correctly made the bike so much better.
I am all thumbs but besides saving money I now know where stuff is, how things are connected and how the dealer screwed me. (They closed right after the service which may explain a lot).
