the key is just a reference,the trick is to make sure the taper is smooth with no high spots(valve grinding compound will help with this).Again make sure its tight.

put some on the crank taper and twist the flytwheel back and forth a bit to remove any highspots,i usually do a dozen twists or so.clean off and put some loctite on the shaft and install flywheel,i can ALMOST guarantee your days of shearing keys are over..at least with that bike.
