I own a 2003 Monster 800. I went on a 4000 mile gorgeous solo journey this summer, my litlle monster was like a perfect pony. Awesome. I wore out a set of tires and when I returned to LA, I brought my baby in for tires and routine service. That was in September. When I got the once perfect Monster back, it felt all wrong. Undescribable vibration of unknown origin, fuel mixture problems, rough, and ugly and very far from from perfection. It was Never the same again. It has been back in service since Sept. 26, and no one, including Ducati North America's top guys can get it to run right. No longer under warranty. what do I do? I want my perfect little monster back. But if it will never be able to run right again, who's responsible? Less than 14000 miles. Sad in California.
