Went to the dunes for a day of riding, swimming and eating. Weather was perfect, and sand was nice and tight due to the rain the night before. Got to run the Tri-z hard, but came away a bit disappointed at power output. It runs extremely well, and is the smoothest 2502t engine ive ever had. But WOT power is soft..........imo. But everyone came home in one piece, and all machines ran well. The QR500 suffered the only failure at the end of the day. Think the big pin bearing failed due to age. Slowly got very loud in the bottom end and it was shut down before complete failure. Gonna git back out there Sep 17.
