Frequently Asked Questions

What valve sizes suit the larger lapping stick?

The double-ended stick has 1-1/8 and 1-3/8-inch suction cups for compatible larger valve faces.

How should the cup size be matched to the valve?

Choose a cup that grips the cleaned valve face securely while remaining inside the valve's outer edge. A cup overlapping the edge will not seal or control the valve correctly.

What must be done after valve lapping?

Inspect the contact pattern and seat width against the engine specification, then clean all abrasive compound from the valve, seat, guide and cylinder head before assembly.
