1974 Honda CB750K · Engine Buying guide
An oil change, an external leak and a top-end rebuild need different parts. Choose the repair area first, then use the listing details and engine measurements to build a suitable parts list.

Oil seepage, noise and low compression need different checks. Establish which assembly needs repair before selecting a gasket set, piston kit or timing-drive part.
Routine filter service and internal engine work have different requirements. For a rebuild, compare the complete gasket list with the assemblies being opened, then account for seals, rings and hardware supplied separately. Check each product’s quantity so a one-cylinder item is not mistaken for a complete engine set.
The featured overhaul set lists its gaskets, valve stem seals and other contents individually. Engine oil seals and cylinder head nut covers are excluded. Compare that contents list with your repair plan before adding separate items.
The eight-piece kit lists the 25 × 62 × 8 mm countershaft seal for 1971–76 CB750K applications. Its second countershaft seal, 29.8 × 62 × 7 mm, is listed for 1977–78. Select the appropriate alternative for the fitted assembly rather than installing both.
One cylinder: it contains one piston, pin and two clips, with rings sold separately. The matching standard ring set also covers one piston. Order each required one-cylinder item for the number of cylinders being rebuilt.
