1978 Honda CB750K · Gaskets & Mounting Hardware Buying guide

Check sealing pieces and mounting hardware separately

The gasket listings identify exhaust port sealing pieces, while studs and flange nuts are supplied together in one set. The flange clamp is sold individually. Read each selling unit before planning the quantity for your repair.

Use the selling unit to plan the order

The stud set lists eight studs and eight flange nuts. The flange clamp and headpipe gasket listings describe individual items, not equivalent complete sets. Inspect which pieces need replacing and count them separately; buying a set of studs does not add sealing gaskets or stock-type clamps to the package.

Compare the connection that is actually fitted

A motorcycle with an aftermarket exhaust may have different connection hardware from the stock-type product photographs. Identify the installed flange, studs and sealing joint before choosing parts. Match the missing or damaged piece to its own listing rather than treating a model-year tag as proof that the installed system uses it.

Common questions

What does the exhaust stud set include?

Its listing specifies eight exhaust studs and eight flange nuts. It does not name gaskets or flange clamps as contents. Match those listed pieces to the work planned and inspect the separate gasket and clamp products where they are needed.

Is the flange clamp sold individually or as four?

The listing describes four used per bike and says the clamp is sold individually. Those statements distinguish the bike requirement from the selling unit. Count the clamps needed for your repair and order that quantity rather than assuming one purchase contains four.

Are the two gasket listings part of the stud kit?

The headpipe gaskets have separate product listings and are sold individually. The stud kit describes studs and flange nuts. Compare each gasket’s stated reference with the installed joint and order only the sealing pieces needed for the exhaust repair.
