Splitting crank case

Can anyone tell me how to split the crankcase? I took out the bolts at each back corner and the top bolt for the waterpump or somethin idk dont remember what it was. I couldnt see anybolts on the front of the engine that looked like they needed to come off. I also have the flywheel/stator and the gaurd around the outside removed. Is there something im missing or do i just have to break the seal now. What is the best way to do that.?

First think I would do is to make sure I have an exploded parts diagram of the engine block. that way you know how it comes apart and how it goes back together.

The cases are sealed with basically thin silicone so they're stuck together pretty well. What I've done in the past is thread in a few of the bolts and tap on those with a rubber mallet (or dead blow hammer) and separate the cases.

The manual actually says..."separate the crankcase halves by installing to of the cap screws in opposite corners...using a plastic mallet, tap on each cap screw until the halves separate."

hope that helps! good luck
