After we receive your cylinders we will inspect them and determine what oversize pistons it will take to make the cylinders straight. Then bore the cylinders on a boring bar, final size with a precision hone, followed by chamfering the ports and a final hone.

Our strict quality control policy ensures specifications will be met. The cylinder is bored, sized, and followed by a three stage chamfer to ease the rings back in and increase engine life, and final hone for the proper cross hatch.

Send your piston and we will bore your cylinder up to 0.040" oversize to fit.
