1983 Honda CB1000C · Valvetrain Buying guide
A clearance adjustment and a cylinder-head rebuild call for different parts. Use the CB1000C inspection results to build the order rather than replacing valves, seals or spring hardware simply because the head is accessible.

The box supplies two each of 2.30, 2.40, 2.50, 2.55, 2.60, 2.70, 2.80, 2.90, 3.00 and 3.10mm thicknesses. It is a selected assortment, not every 0.05mm step. Honda’s original CB1000C manual describes a broader 2.30–3.50mm shim range; that factory range is not the contents of this kit.
Honda’s original CB1000C valve procedure says the valves cannot be ground and calls for replacement when their faces are rough, unevenly worn or contact the seats improperly. Have the head specialist distinguish valve replacement from valve-seat work before ordering. This original-valve instruction does not establish the reconditioning limits of every aftermarket valve.
No. The required thicknesses and quantities depend on the clearances and shims already fitted. Several valves may need the same thickness, or a size absent from the assortment. Compare the completed measurement sheet with the box contents before choosing the kit or individual replacements.
No. A seal set does not restore the fit between a worn valve stem and its guide. Honda’s cylinder-head procedure checks that clearance separately, so have the valve and guide condition assessed before treating a seal-only purchase as the repair.
