Installation Notes:
- Deglaze Cylinder When replacing a piston with the same stock bore size as the original factory stock size you do not need to have your cylinder modified. We do recommend that you deglaze the cylinder. This involves running a hone through the cylinder to remove glazing and provide the best possible surface for piston ring seal. This will improve power and piston and ring life.
- Bore and Hone Cylinder When installing an oversize, big bore piston, the cylinder must be bored to the correct new bore size to allow installation of your oversize piston. The cylinder then must be finish honed to provide the proper surface for your piston and rings to work in, and provide best power and longevity.
