+  * It's very important to hold the crank still from the cam side (not the primary side) when torquing the pinion nut. ((aswracing of the XLFORUM http://xlforum.net/forums/showthread.php?t=1666277)) \\ If you for example put the bike in gear and hold the rear brake and torque on the nut, you run the very real risk of knocking the crank out of true. \\ It's not designed to transmit torque from one side to the other and it tries to twist the crankpin connection.
+  * In respect to the key shearing, it's a very common issue particularly when heavy valve springs are used. \\ However, it shouldn't be the one thing that keeps the gear from spinning. The clamp load should do that. \\ The caption in the second pic below describes the fix: \\ Loctite red and 70ft-lbs instead of the factory specified 50ft-lbs. You won't have this issue again. \\
