The bike had been running good for the first 500 miles, but started to cut out and stall on last Sunday's ride. Mostly happened on tight, bumpy trails. The bike ran perfectly on the pavement, so I suspect that there might be a bad connection or a loose wire somewhere. Since it's under warranty, I dropped it off at the dealership. I can't wait to get it back and install my new Guts Racing saddle on it. It's got standard height soft foam, which is what I run on all my other Husqvarnas, and they are very comfy. This Seat Concepts saddle is literally giving me a butt ache!
