Mounting and sealing the tank

The front and rear tank cushions have different references. The emblems and their clamp nuts are also individual products, so match the fitted tank and hardware before ordering.

Badges for the Supersport

The emblem is listed for the 1975–76 CB750F, with 110 mm post spacing and 175 mm overall length. Its separately sold clamp nut replaces 87311-634-600 and 87311-516-000 and explicitly includes the 1976–78 CB750F. Both are sold individually.

Petcock thread size

The supplier asks buyers to compare the tank thread, sealing arrangement, outlet direction, hose size and lever clearance with the original valve before ordering.

Tank questions

Can I choose the later CB750F petcock instead?

The selected 20-8038 petcock replaces 16950-341-671, uses an M20 × 1.5 thread and lists the 1975–76 CB750F. Petcock 20-8037 replaces 16950-393-015, uses an M16 × 1.5 thread and lists the 1977–78 CB750F with a right-facing outlet. Its listing does not confirm 1976 CB750F fitment; match the actual tank connection rather than assuming interchangeability.

Is the emblem clamp nut an ordinary threaded nut?

No. The listed clamp nut is a push-on retainer for the matching emblem stud. It replaces 87311-634-600 and 87311-516-000 and is sold individually. Confirm the stud diameter and retainer style before choosing replacement hardware.
