Lupe,
Mine is a 2000 so I still have to adjust the valves, no big deal, it takes about 15 minutes and a hell of a lot easier than a vintage Triumph. They started hydraulic valves in the EV1100's in 2003 I believe and there were some issues and recalls from 03 to 2005. if you are looking at those years make sure the recalls were done and Moto Guzzi is still honoring them even today. The bike sounds and rides like a garden tractor, I can't really describe the attraction, other than the **** thing is fun........
