Im sure there are many threads about this already but. . . . . . I have all the screws out of my crankcase and im trying to figure out how to get the case apart. I watched fred chelminski video on youtube about taking the case apart. Ive done everything he did except take the actual case apart. In the video he says he has had that specific case apart numerous times. So i guess thats why he made it look so easy. . . Any tips?
