You might give Roger a call at On Road/Off Road. He is south of the Y. I was most impressed with the work he did rebuilding the FD on my 1100RT....very upfront/no BS kind of a guy. He's a Monster owner and a real enthusiast. We struck up quite a conversation about Ducatis when I picked up my final drive. He has not worked on my Ducati personally but will definitely give him consideration come time. I hear he is one hell of a suspension guru as well. Maybe someone can speak from first hand experience.
http://www.ororcycle.com/Don Lackey is also one hell of a mechanic and did the 12k mile on my 748S. He's up on Nameless Rd in Leander. Very fair price and the bike ran like a top when I picked it up. Don is also a Ducati owner (996S I believe) and knows his stuff. Georgetown Powersports may have his contact info. I will have to dig to get it...been a while since he did the work on my bike.
These of course or independent mechanics if you feel comfortable with that. For belts and valves I don't think you could go wrong with either one but YMMV.
