Your good self and your kind self were friendly usages, not deferential. They were most frequent in the 18th century and largely died out by the early 20th century. As you may see from the Google Ngram below, neither was ever very common: your good self peaks at about one hit for every 1600 hits on the usual deferential form sir, and its rise is mostly to be attributed to decline in the use of sir.
If you follow up recent uses you will find that almost all the valid hits occur in reprints, historical novels, or works in the English of former colonies. I advise you to avoid these phrases in contemporary Anglo contexts, and stick to sir.
