Motorcycle Repair: cylinder removal, helpfull tips, doesnt work

Question
I have an engine that is locked up, I've removed the heads but the cylinders won't budge. I'm trying to locate the problem and do a top end rebuild.  Any suggestions or helpfull tips?

Answer
Sounds like you seized a piston. Pull the cylinder up as far as you can and having somebody holding it or put somthing under it, use a block of wood and drive the piaton out of the cylinder. If that doesnt work then you will have to drill alot of holes in it around the edge of the piston and then try to drive it out.
Good luck and happy riding
