Hello everyone. I have a Honda s90 that I'm need if trying to obtain the correct year of. I know they are from 1964 to 1969. I've been told I have a later year as mine has the Mikuni II carburetor. I have the frame number and trued contacting Honda about this and they said they couldn't access any information on it. The correct year would be great to know as I don't want to order parts for my restoration and have to keep returning them. Sny help would be greatly appreciated. Thanks in advance.
