OEM Yamaha reference for Cylinder/Piston sizes and piston-to-cylinder clearance.
Warning- If you are reusing your cylinder, measure the diameter of the cylinder in order to match the correct piston size for optimal performance. Over time, the cylinder diameter will increase as it is being used. If the cylinder is over the maximum diameter size, it is highly recommended to either replate the cylinder or purchase a new one.
