Posting this here as it seems the appropriate place
Kawasaki owners/restorers place emphasis on correct date codes. I've posted previously about date codes but I want to stress how important it is to keep original parts where possible. Nearly everything has a date code on early Honda machines. This includes such insignificant items such as rectifiers and coils
The following are the codes to look for
44 = 1969
4 = 1969
5 = 1970
9 = 1969 or September or 9th day. Depends on the location of the code so 999 (90909) could mean 9 Sept 1969
A, B, C = Oct, Nov, Dec
X, Y, Z = Oct, Nov, Dec
You may also see symbols on parts which at first sight are meaningless but in fact are Kanji or Katakana symbols which can represent numbers as date codes. I'm not about to list these as there are hundreds so google Katakana to see the numerous symbols. Often seen on early rod ends and engine parts
Here are some coils with date codes often missed by restorers. If the coils are beggared then not a lot you can do Even later manufactured coils have a code 1x could be Oct 81 or 91
