[René 衛星の]

Hi, I am looking for the sizes of 18391-392-000, muffler gasket foer the CB750F1 and CB750a (76) models, large one.

Anyone has these available?

This part is no longer available from HONDA, as you will know. Trying to fin an aftermarket one.

There is a company here called McMaster Carr that offere a graphite tape that can be wrapped around the  header several times to recreate this gasket. I have used it on my GoldWing  after mounting some aftermarket mufflers. It comes in different widths and is about .020 inch thick so 10 layers is close to .2 inch or 5mm. I can look up the Part number if this helps.
