Was thinking of just putting a new piston and sleeve and orings in it, maybe a new crank. It was measured and did show signs of wear but with in tolerance. What's the plus and minus besides cost? The piston and sleeve cost is a non issue. I already did new bearings, block is still nice, head is nice still, button is good. I was told to just paper weight it because it'll never be the same. I was thinking it would be at least a good practice/club race motor....
