1977 Honda CB750K · Engine Buying guide

Find the right starting point for your engine repair

Sealing an external leak, replacing a filter and rebuilding a cylinder call for different parts. Use the repair area to narrow the choice, with particular attention to late-model seals and piston packages.

Parts to consider

Late-model seven-piece oil seal kitSeven oil seals, including the countershaft seal listed as 29.8 × 62 × 7 for the 1977–78 CB750K application.View part

76 CB750F / 77-78 CB750K Piston Kit ~ 61mm Standard Bore

61mm standard-bore piston kitAftermarket 61 mm standard-bore kit replacing 13101-392-020: one piston, pin, clips and five-ring set for one cylinder.View part

Start with the assemblies being opened

List the repair locations before adding a broad rebuild package. The overhaul gasket set covers multiple engine joints but excludes engine oil seals and cylinder head nut covers. A cylinder-only job may call for the top-end package instead. Read both contents lists to avoid missing pieces or unnecessary duplicates.

Keep late-model choices separate

The featured piston kit and seven-piece seal kit explicitly list the 1977–78 CB750K. If the engine has been exchanged or its cylinders have been bored, those details need checking against the installed parts. Model-year fitment does not establish the current bore size or the contents of an earlier rebuild.

Common questions

Does an overhaul gasket set replace the separate oil-pump service kit?

The overhaul set includes an oil-pump gasket, but the eleven-piece pump kit also lists stopper and relief-valve springs, seals and O-rings. Compare the diagnosed pump repair with both contents lists; a shared gasket does not make the packages equivalent, and neither is a complete pump.

Why compare the piston-only listing with the piston kit?

Both standard-bore products use replacement reference 13101-392-020. The piston-only listing excludes rings, pin and clips, while the piston kit supplies those pieces. Choose the package around the parts needed for each measured cylinder rather than the shared reference alone.

How does an exchanged engine affect cam-chain-guide selection?

The featured guide lists the 1973–78 CB750K and also a restricted 1972 application above engine serial 2200000. Identify the engine actually fitted before relying on a 1977 frame year; the listing’s condition belongs to the 1972 engine application, not a general frame-number cutoff.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
