S&S 41/8" pistons are machined to such close tolerances that it is not necessary to measure the piston Additionally, the low friction coating on the piston skirt of early production pistons without micrometer window makes taking measurements very difficult Therefore, hone cylinders to nominal diameter +/- 0 0001" for correct clearance Current production pistons have micrometer windows in the coating on the piston skirts that allow accurate measurements to be taken These pistons may be installed by honing cylinder to nominal diameter +/- 0 0001" or by measuring piston and honing cylinder to achieve 002"– 0025" close clearance for street applications or 0032"– 0045" loose clearance for immediate competition use
