Interesting. I recently searched all over for gears for my Sport and none were available. Fortunately I found a guy, locally by my good luck, who specializes in fixing motorcycle transmissions. He welded up the rounded dogs on four of my gears and then re-cut them. Did a beautiful job and charged me $340. 30 years in the motorcycle transmission business.
