I have a seized engine, I have removed the bolt to the base of the jug and tried to rock it back and forth get it loose, this thing is pretty stuck, I rebolted the jug and I would like to use some kind penetrating oil to free this thing, I was thinking of adding some WD-40 to the cylinder let it soak overnight and trying to use the kickstart to free it. I have hear mystery oil and other oils, If i can get some ideas or suggestions to removing this piston. thank you =)
 
So how should I turn the motor then to free it up? I've heard rocking it back n forth in gear will that work?
 
Penatrating oil might work, but if it's stuck that bad I doubt it. I would make a puller simular to a harmonic balancer puller. This will give you a idea : harmonic balancer puller - Google Search
using two or three of the head studs and a jack bolt in the center.

If the engine is out of frame you could caveman it, one guy hold cylinder and another tap the piston with hammer and block of wood.
