go to google and search 400cc stroker kit, it should pop up with an alba kit, its awesome, it tells you everything you should do and have to run that kit, my buddy and I just finished putting his together and it was all pretty easy, no case mods required, if yu dont bore your stock cylinders with this kit it about a 375cc, if your going to put a stroker in you'll need new pistons, you should also get a pro design cool head and you have to get the domes cut to where the piston doesnt smack the top, you'll need new carbs i suggest 34 mm pj's or 35 mm pwk. v force 3 reeds, if you live in the san diego area, I could probably help you out.
