Piston: Service and Repair
Pistons, Oversize
Standard size pistons and rings are color coded red or blue and oversize pistons and rings have .004 OS stamped on their dome. Piston to bore
clearance should be .0012---.0020 in. on 1982 models and .0018---.0026 in. on except 1982 models. Measure cylinder bore and select a piston to ensure
proper clearance. When the piston to bore clearance is in the lower {1-3} of the specified range, a red piston should be used; in the middle {1-3} range a
blue piston should be used and in the upper {1-3} range a .004 OS piston should be used. Piston pins are not available in oversize.
