A few years ago I bought a cyl/piston assembly as a spare for my 2 K&B 28 Sportster engines. I now have need of it but when I came to fit the wrist pin I found that there was no blind hole in the piston. It has somehow not been machined at the factory. How can this situation be resolved without me having to buy another cyl/piston assembly.
