Dear all,
My name is Patrick, living in Lyon - France, now retired and spending a lot of time in restoring Hondas from the 60's and 70's.
I am sorry to say that I have no sandcast in the garage, my collection has a CB750 for sure but a K1 1971.
Other bikes : CZ100 1964, CF50 1967, PF50R 1973, ST70 Dax 1974, SL125 K1 1974, CB350 K2 1971, CB450 K2 1970, CB500 Four K1 1974, CB750 Four K1 1971.
Otherwise I am co-founder of the French Honda forum cb500four.com and by the way I have many contacts with French amateurs. I was very interested by your forum and I signup as I have some information to add.
