NOTE: S&S 41/8" pistons are machined to such close tolerances that it is not necessary to<br />
measure the piston. Additionally, the low friction coating on the piston skirt makes taking<br />
measurements very difficult. Therefore, hone cylinders to nominal diameter +/- 0.0005"<br />
for correct clearance.<br />
