I've just removed 98's from my 500 carbs to fit 105's. If you drop me your address you can have them.
I don't think that's correct, never seen or heard of a #78 main jet on any Honda, let alone a CB500/4 🤔🤔🤔🤔

Again, see the parts lists. Also Honda listed the #78 main jets as a possible alternative for the standard #75 on the CB400F.

It was a simple thread that has got stupidly complicated for no reason.
...So, a 1971 500/4 has 627A, a 1972 CB500/4 has 627B's...
