"bypassed a torque switch"--- :strokin: Go to a different dealer. Otherwise maybe you stretched your timing chain beating on her out in the dunes. Kind of tough to call with out riding her. I want to say carb, but you said it ran great for two days first. It's possible you got some junk in the carb and it's clogging up the one or more of the jets. Have you taken it apart and cleaned it? That would be my next step or go to a different dealer.
