How to split kx crankcase?

[kwacker]

Hi!
I have a KX 80 ´84 and trying to split the crankcase in order to renew crank main bearings.By now I have removed clutch,kickstarter and every other component(including bolts),that hold the tranny together.Two halves have already splitted about 3mm,but that's where it seems to wanna stop :think: .How should I continue??I don't wanna break anything!

how did you get them to split the first 3mm? ONCE all the bolts are out, you need to tap around the case with a plastic hammer
