Choosing the Right Size
Each cylinder is stamped with a size code (A/B/C/D) to indicate precise internal diameter.

• When new: match piston and cylinder codes (e.g. “A” piston for “A” cylinder)
• After wear: move to the next size code (A → B → C → D)
• After final size: re-plate or replace the cylinder

⚠️ Always check your cylinder’s size code before ordering. Using an incorrect piston size can cause poor performance or engine damage.
