The overhaul set names clutch, shift, alternator, oil-pan, oil-pump and starter-cover gaskets alongside its top-end items. The Athena set concentrates on the top end. Mark the repair’s opened joints against those lists rather than assuming the larger-sounding name includes every sealing piece.
The separate shift-shaft seal is marked 14 × 28 × 7 and replaces reference 91206-286-013. The engine oil-seal kit also includes a shift-shaft seal. Compare the repair location and the kit contents before buying both.
The Athena top-end set contains six head nut covers. The overhaul set expressly excludes them, so this is worth checking before adding a separate cover pack.
No. Two are alternative countershaft seals. The contents specify the 25 × 62 × 8 version for 1971–76 CB750K applications and a separate 29.8 × 62 × 7 version for 1977–78.
Both featured gasket sets list a cam-cover gasket. Add the separate cam-cover product only when the repair needs it independently or you have a specific reason for another one.
