You can do it....
You have to dis-assemble the clutch side, which is a simple job, take out a couple phillips screws and thats it. I would get a flywheel puller (like 15 bucks from FAST) to get the flywheel off so you can get the stator off. To get the gear off the crank you take the clutch gear out by taking the clutch out, and then taking the nut off the crank and grabbing the gear with your hand and jerking if off of the crank. Very easy stuff. if you take your time, and use common sense, you will have no problems doing it yourself. Call Jeff at FAST, and get new gaskets, some case sealer, and a flywheel puller and you should be good to go.
