The F tank emblem

The emblem is listed only for the 1975-76 CB750F Supersport and matches OEM 87122-392-000 and 87121-392-000. It measures 110mm between posts and 175mm overall. Order the clamp nuts too if the old ones are corroded.

Petcock thread check

The petcock uses an M20 x 1.5 thread and replaces OEM 16950-341-671. Its listing asks buyers to verify the thread before ordering. Drain the tank and fit a new seal so the joint does not weep.

Tank questions

Is the tank emblem specific to the F?

Yes. Its fitment names only the 1975-76 Supersport, and it matches OEM 87122-392-000 and 87121-392-000. The description says it follows factory sizing for correct placement on the tank.

How many rear tank rubbers are used?

One per bike, according to the rear holder rubber description. It replaces OEM 17613-399-000 and covers the Supersport from 1975 to 1978, so it suits this bike.

What thread does the petcock use?

An M20 x 1.5 thread, replacing OEM 16950-341-671 on the 1975-76 Supersport and some smaller Honda fours. The description asks you to confirm the thread on your tank before ordering.
