Default what piston size for re-sleeved cylinder?

     

I'm currently rebuilding my 98 cr125 that I just bought and I put a new piston and ring on the top end. When I took the cylinder off, I noticed that the cylinder was re-sleeved. I put the new OEM Honda piston and ring and new bearing and clips in. I tested the compression and all I got was a max of 60psi. I'm assuming that the piston isn't the right size for the cylinder cause I thought there was too much play between the piston and the cylinder. So now how do I find out which size piston I need to get?

go to a shop which repairs or re-sleeves car engines and let them measure the bore. With that value you look for a almost as big piston. A little smaller like 0.05mm
