1969 CA77 Float Valve Set

[quidger]

I own a 1969 CA77. I want to order an OEM float valve set but I’ve run into an issue identifying the part #. All of the Honda dealers’ parts fiche’s only show part #’s for the “early models”, 1961-1963. The 1964- 1969 models are considered “late models “. The part # that in find online for the early models is 16011-375-004 and it’s available through my Honda dealer. Bill Silver’s Parts List shows the round bowl Keihin , which would be from early models, as #16125-259-004. I assuming that Silver’s part number is correct so I’m wondering if the 16011-375-004 is actually the correct part for the late models. The 16011-375-004 replacement part is 2.5 mm and the seat in my 1969 carb is marked 2.5. It makes sense to me that if parts for early models with fewer years of production are available that the late models with more years of production would also be available.
If anyone can chime in with information that might be helpful, I would appreciate it.
