Assuming your using a manual so you know you have all the correct bolts out. Find any space that has a good amount of meat (Cast) and whack it with a rubber mallet. As long as you dont whack a thin spot dont be afraid to hit it good.

Make sure you have the clutch assembly out and just keep working it don't pry on it to get it open if you do this and pry to hard the cases wouldn't set, rubber mallet and just keep working it you can take a very thin knife or blade also and put it between the classes.

DO NOT DO what this person is telling you. Dont shove any piece of metal or anything for that matter between cases. Rubber mallet is all you need.

Why would you chance fucking up the surface of that soft aluminum by prying the cases apart with a harder metal?

It's not prying it's losing up the gaskets with I thin metal blade
There is no gasket between the case halves. It's metal on metal with a sealant. Shoving anything in there can cause problems with the cases leaking forever. O.P. please post some pictures of what you've got right now. Show all sides, top and bottom. There are people on here who've split these cases and can doublecheck to make sure you're not missing anything.

I know what you're saying, but a beginner shouldn't have tools of destruction anywhere near a machined surface. I'm just trying to save everybody a headache.

Everyone always wants to take the ez way out. Exactly why i said do not listen to other poster. Good luck with a little stone rub.

using a thin sheet of brass or copper as a "knife", or some really hard plastic generally prevents that.

You didn't by chance buy that from a guy in Bradenton, FL. selling it as "stripped" for like $1000 did you? If so I was gonna buy that bike. Would have only offered him $500 though.
