CB77 Exhaust Copper Crush Gaskets

Post by dragonfly888 » Thu Mar 18, 2021 7:17 pm

Wondering if anyone knows the size of these gaskets?
And where to get them?
I have tried a search here, but received errors.
Thanks very much!

I just measured the outside diameter of a pipe with its collars. It is 45 mm. Inside diameter is about 32 mm. Hope this helps.

Part # 18291-254-000

They fit many different models, should be able to get them at any honda dealer or parts outfit.
