So i changed my chain and sprockets and noticed that my sprocket cover had a very small crack on it by the clutch slave, so i orderd a new one rode about 20 miles no problems then my spedo stoped working got home and my new sprocket cover was toast major crack on it all the way down. So i figure i need the support piece and order one along with a new sprocket cover. While I was sitting in the garage staring at the busa dreaming of riding it again one day if the parts ever get here, I started to look at the sprocket cover that just broke and seen that the bolt that holds the sprocket on some how wore a grove into the cover and im assuming that it caught the cover and cracked it? but how? the bolt is tight as can be sprocket is installed correctly. Any ideas?
