1981 Honda CB750F · Engine Buying guide

Build a parts list for the engine work ahead

Start with the repair you have identified: oil service, gasket work, valve-shim selection or a more extensive rebuild. Compare the actual contents of each selected product before combining purchases across these jobs.

Parts to consider

Match the purchase to the job

For routine oil service, establish whether the factory-type paper-element housing is still fitted. The chrome spin-on conversion 15-1006 is listed as replacing the housing, filter bolt and paper element. For gasket work, compare the named joints in the overhaul and top-end sets with the scope of your repair.

Treat measurements as buying information

The valvetrain selection includes a shim assortment and individually sold sizes; neither tells you which shim your engine needs. Piston rings also have standard and oversize choices. Keep the old parts, measurements and repair scope together so a convenient bundle does not replace a decision about the actual engine.

Common questions

Do I need separate rings and pin clips with the standard piston kit?

Piston kit 07-0184 lists a piston, rings, pin and a pair of clips for one piston. The separate ring sets supply rings only, and the loose 15mm pin clips come in a two-pack. Check the chosen package before adding duplicate rings or clips.

Does the Athena overhaul set already include exhaust gaskets and the camshaft-holder seal?

Yes. Overhaul set 18-0109 lists a four-piece exhaust-headpipe gasket set and camshaft-holder rubber seal 18-7066. Check those inclusions before adding the same loose parts to a gasket order.
