I also have an '05 Rocket. I bought it second hand and have not had problems with it. It had undergone the 500 mile scheduled maintanence (maybe a little late) but I have had no problems issues with idle or how it performs. It had the final drive issue addressed before I purchased it. I am so giddy every time I climb on board & fire it up. I plan on getting the PCIII or the Tumeboy next spring to see what extra reponse I can acquire from a good throttle "whacking" but I could not be any happier, unless I had 2 Rockets.
See ya.
