Ok my motor is locked up. Tried to turn it over with the kick start and it wouldnt budge. Tried rocking it back and forth only to.notice the chain was broken. So at this point i have taken out the old spark plugs and poured marvel mystery oil down the cylinders. Before i go romping on it again does anyone have any thoughts on what it could be or if the motor is even worth rebuilding.
 
I'd do more than pull the plugs. Take the head off and get a better idea about what's going on.
 
Thats the problem with seized motors.... you dont know till you open them up. Look on CL and see if you can find a replacement for cheap. also, check the oil on your motor, check the level see how much is in there and the color/texture/smell. then drain the oil and check for aluminum/metal in the old oil.

How did it seize? was it a barn find that sat for 10+ years or overheating?
 
The bike to my knowledge sat in the barn for years and years. The one owner it had was some guynthat moved away and left the bike in his parents barn. Shows to have about 700 miles.on.it.but im not sure how true that is.
 
Pray the rings rusted and frozen, as stated previously, I'd pull the head and see what ya got goin in the piston and cylinder department.
 
yeah don't go crazy trying to kick it over and break that off or do anything else to the bike. definitely change/check the oil and doesn't hurt to take the valve cover off. mine had a bent valve and the tappet was bent. also the marvel mystery oil is good too
