By taking it apart and put it back together you have to be sure the sleeve is located in the right way. Sometimes the center pin is lost or what I have seen with non listed Novarossi products they have put 2 slots for the center pin into the sleeve. Also be sure the piston/rod is placed in the right way.
And if you did remove the main bearing putting it backwards in you also will face some binding issues.
Yes made sure the cylinder was placed correctly, only goes in one way really. Same goes for piston, I identified the exhaust port side and installed it as such. I did not remove the bearings as I do not have the proper tools to press them back in.
