Use the 5mm allen tool to remove the stator cover (left side of bike)
Remove the bolt in the middle of the flywheel (you may need a breaker bar)
Screw in the flywheel puller (tighten to around 20 Nm or so, as long as its not loose)
Take a hammer and whack the flywheel puller (Careful, don't damage the flywheel)
It may take a few whacks for the flywheel to loosen, it should then just slide right off
After removing the flywheel there should be a flywheel key (a little half moon shaped bit of metal ) that holds it in place, don't lose this.
