1978 Honda CB750P · Engine Parts

Choosing engine parts for the 1978 Honda CB750P

Start with the job you are doing: fixing an oil leak, servicing the top end or rebuilding the engine. Compare each listing’s stated model and year with your 1978 Honda CB750P, especially if a previous owner fitted a replacement engine. An OEM or reference number can help identify a part; also check its dimensions and application notes.

For pistons and rings, confirm the measured cylinder bore and the listed size before buying. A standard-bore part and an oversize part are different choices. Check whether a gasket set covers the work planned or whether you need separate oil seals, O-rings or other service items.

Read the supplied contents and quantity on each product page. A kit may cover one cylinder, one assembly or a specific repair rather than the whole engine. Follow the workshop manual for inspection limits, clearances, tightening sequence and torque values.

Engine Parts buying questions

Can I choose pistons or rings by model year alone?

No. Confirm the bore size and condition as well as the product’s stated application. Previous machining can change the size your engine needs.

Does a gasket set include every oil seal?

Check the product’s contents. Gasket sets and oil-seal sets can cover different items, so match the supplied pieces to the repair you are doing.
