Should be a piece of cake if you've done two strokes before. The Magnum looks just like an OS to me and there is a great video on youtube.com on the disassembly and reassembly of an OS on there. You basically just have to watch your cam timing, make sure it is exact, and your valve clearance. Really not that much to it, Shoo
Here's the youtube link to disassembly, the reassembly videos are there too:
