Replacing the stator is a pretty standard procedure regardless of the sled make or model, so you should be able to find plenty of info on replacing the stator in a snowmobile. It’s pretty easy.... Pull the exhaust, pull the starter off, remove the flywheel cup, remove the flywheel and the stator is underneath the flywheel. You will need a flywheel puller or some type of harmonic balancer to get the flywheel off. I bought a universal flywheel puller from Dennis Kirk for about $30 but I hear you can use a harmonic balancer or steering wheel puller available at an auto parts store. Plenty of people to help you here, so ask any questions and good luck.
