I got the cases back from being helicoiled and stuff. Good clean up, nicely assembled. Now the oil pump is super tight. I completely dismantled it and cleaned it. theres no sign of distortion. The pump is so tight it hinders the rotation of the crank. Also somebody cut the cylinder head steady mounting ear off the head, so no mounting point for a head steady. BSA M20 M33 B33
