Quote from: Nurse Julie on November 20, 2019, 06:47:28 PMI don't think that's correct, never seen or heard of a #78 main jet on any Honda, let alone a CB500/4 🤔🤔🤔🤔 Except for France, all CB500s on continental Europe had the #78 main jets. Again, see the parts lists. Also Honda listed the #78 main jets as a possible alternative for the standard #75 on the CB400F. See the CB400F parts list, p.17 http://www.honda4fun.com/pdf_parts_list/pdf_spac400/CB400F-F1-F2/CB400F-F1-F2.pdf

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...
I just checked, I actually have two sets of 4 carbs. The ones on the bike are 087A and the others I have are 069A. The plot thickens!
... An indication also is that this F2 had a fast cam and the chokeknob on the handlebars...
