Pop the masterlink off. Put in neutral. Pull the chain out. You'll have to fish it back over the sprocket to put it back together, but it'll be easier than taking it all apart.
If you want to get at the sprocket you have to remove the hi/lo assembly, Pull start, then the stator plate. Its not that bad, just time consuming. Its in the 200e manual.
