The Athena overhaul set already lists eight cylinder stud packings and a cam-cover gasket. Those individual products are useful for narrower repairs, but check the broader set before adding duplicates. Its oil-pan contents also name both early and late gasket references; identify the pan fitted rather than assuming every supplied gasket belongs on one engine.
The economy kit lists a 25 × 62 × 7.8 countershaft seal and a 13.7 × 24 × 5 clutch-arm seal. The eight-piece kit lists 25 × 62 × 8 and 14 × 24 × 5 for those entries. These are the sellers’ stated replacement dimensions; compare the exact references and fitted seals before choosing a kit.
The Athena overhaul set includes six. The separate standard overhaul set expressly excludes head nut covers; both sets exclude engine oil seals. Check those differences when comparing total package coverage.
No. It supplies two alternative countershaft seals for different applications. Its 25 × 62 × 8 entry is assigned to 1971–76 CB750K models, while the 29.8 × 62 × 7 option is assigned to 1977–78.
Compare reference 91201-300-003 as well as the listed 30 × 42 × 8 size and the actual sealing location. The listing warns that some covered models use different crank seals, so its broad application range alone should not decide the order.
