Here is one, I purchased a 07 Dragon last January and put 1200 problem free miles on it. This year after about 20 miles it stopped coasting. We stopped and upon starting the drive train was completely locked up. Got it freed and after the run, (100 miles), I checked the track to find out it was super tight. Loosened the track and test drove it, all good. The next morning we left for the return trip. Again after a few miles I could feel the power being sucked up by the drive. Finished the trip and returned home. The next morning the track is again so tight that I could hardly pull it from the skid. It is in the shop now, still under warrenty, waiting to see what they find. Any ideas or similiar occurances?
