Cracking apart the case halves

1981 KZ1000J, I think I have all the bolts removed around the perimeter, but the case halves aren't releasing and I don't see any good spots where I could try to pry them apart to get the seal to pop. So first off, are there any bolts other than the obvious 10mm and 12mm ones that might also be holding it together? I've removed side covers, the plate over the transmission area, and popped the housing around the ignition area, however I have NOT removed the bottom pan (was hoping to avoid that since there still seems to be some oil in the case). And second, if I do in fact have all the bolts removed, are there any suggestions for breaking the seal?

Yes you have to remove the pan, there are case bolts under it. Two under the oil pump and two opposite. There are four in the middle for the crank bearing, those do not have to be removed to split the cases

Correct, remove the pan. Nice pic Greg. No pry screw bosses and oil scavenge plates cast in?

Well crap, that certainly explains why it didn't want to pop apart easily. Got a storm moving in tomorrow, maybe I can find a big pan to flip the engine upside-down onto so the rest of the oil can drain out until I have another chance to work on it. Thanks for the info, this is why I didn't try to force it.

The early engines have three threaded bolt bosses so you can use the crank bolts to pry the cases apart. Trouble is if you don't get all the bolts you could crack the cases. Make sure you get the few bolts on the top and all the bottom ones. The pan has to come off and the oil pump should be removed.
Do you have a manual?

Well I'm getting closer... got the oil pan off tonight and those four internal bolts removed, still not budging though. I don't see anything else on the underside, so if I get a chance tomorrow I'll flip it back over and re-check the top to make sure I didn't miss anything else.
