You might want to take the carb(s) and bodies and exhausts off and spray oil below the piston(s) as well if you can to try and free the bottom of the cylinder. Like mentioned keep putting oil in very day for a week and leave standing, it may free up then. If not you're gunna have to strip it down to get the con rods off the crank to take the top end off. Good luck
